How to Apply for a U.S. EIN as a Foreign Entity (2026 Step-by-Step Guide)
If you are a non-US ecommerce seller in South Africa, the UK, the EU, India, Australia, or Canada, your U.S. Employer Identification Number is the single piece of paperwork that unlocks everything else: payment processing, U.S. bank accounts, Amazon FBA tax interviews, marketplace facilitator settings, and every state sales tax registration. The catch is that the IRS’s fast online EIN system is closed to you, because it requires a Social Security Number that you do not have and cannot get. This 2026 guide walks you through the exact international pathway, line by line, phone number by phone number.

Why Every International Seller Needs a U.S. EIN
For a non-US ecommerce seller, the U.S. Employer Identification Number is the federal tax identification number that gates almost every commercial step you take inside the United States. It is a nine-digit identifier in the format XX-XXXXXXX, issued free of charge by the IRS, and it follows your entity for its lifetime.
Once you start selling into the United States, you will hit walls without one. Amazon’s W-8BEN-E and tax interview will ask for it. Stripe, Mercury, Wise Business, Payoneer, and most U.S. business bank accounts require it before they will activate your account. Every state sales tax registration form has a field for it. If you plan to register for sales tax without a U.S. address, the EIN is the one piece of ID you cannot work around.
I’m Paul le Roux, a Chartered Accountant with the ICAEW and CA(SA), and over twenty years of cross-border tax practice we have walked South African, UK, EU, Indian, Australian, and Canadian sellers through this exact process hundreds of times. The good news: it is genuinely straightforward when you follow the international procedures the IRS has built specifically for foreign applicants. The bad news: most online guides describe the U.S.-domestic online EIN application, which is closed to you, and following that advice ends in rejection.
The Single Biggest Misconception About EINs for Foreign Entities
The most common myth we have to debunk in the first ten minutes of a client call: you do not need an ITIN before you can apply for an EIN. Many cross-border sellers are told (often by U.S.-based forum posts written for resident immigrants) that they must first file Form W-7 for an Individual Taxpayer Identification Number, wait three to four months, and only then apply for the EIN. That advice is wrong, and following it can delay your business launch by an entire quarter.
The IRS Internal Revenue Manual is explicit: “foreign individuals are not required to have an ITIN in order to receive an EIN.” The EIN belongs to your business entity. The ITIN, if you ever need one, belongs to you personally for filing a U.S. individual tax return. They are separate systems serving separate purposes.
When your responsible party (the human in charge of the entity) does not have an SSN or ITIN and is ineligible to obtain one, you enter the literal word “Foreign” or “N/A” on Line 7b of Form SS-4. That is the correct answer. The IRS designed this pathway specifically for cross-border applicants like you. Apply for the EIN first. Only file Form W-7 later if your specific tax facts require it.
Step 1: Confirm You Qualify as a Foreign Applicant
The IRS draws a sharp line between domestic and foreign applicants because the application channels are different. You are a foreign applicant if your legal residence, principal place of business, principal office or agency, or principal office of operation is located outside the United States and its territories.
Notice this is determined by business location, not by nationality. A U.S. citizen running an ecommerce business from a flat in London is a foreign applicant for EIN purposes. A South African passport holder who has relocated to Florida and opened a Wyoming LLC is a domestic applicant. Get this classification right because applying through the wrong channel ends in rejection.
For nearly every cross-border seller we work with, the answer is obvious: you are based in South Africa, the UK, an EU country, India, Australia, or Canada; your principal place of business is your home or office there; you are foreign. That means the IRS’s online EIN application at irs.gov is closed to you (it requires a U.S. SSN or ITIN for the responsible party), and you must use the international pathway: phone, fax, or mail.
Step 2: Pre-Fill Form SS-4 With Your Formation Documents in Front of You
Form SS-4 (Revision December 2025) is the IRS application form for an EIN. It has 18 numbered lines, a signature block, and an optional Third Party Designee section. You can download it from irs.gov, but do not type anything into it until you have your formation documents in front of you.
Pull the official paperwork that created your entity: Articles of Organization for an LLC, Certificate of Incorporation for a corporation, partnership agreement for a partnership, or the foreign equivalent (the UK Companies House certificate of incorporation, the Indian Certificate of Incorporation from MCA, the South African CIPC registration certificate, the German Handelsregister extract, etc.).
The IRS database performs exact-match validation between Form SS-4 Line 1 and these formation documents. “ABC Trading Company Ltd” is not the same as “ABC Trading Co. Ltd”. A missing comma, a swapped suffix, or an extra space causes rejection. Copy the legal name precisely, including capitalization, punctuation, and any corporate suffixes. Do not abbreviate, do not modernize, do not “clean up” the name.
Step 3: Identify Your Responsible Party (and Why It Must Be a Human)
Line 7a asks for the responsible party, and the IRS is uncompromising on this point: the responsible party must be a natural person, never another entity. You cannot list “Acme Holdings Pty Ltd” or “BrightCorp Ventures Limited” as the responsible party. The IRS requires a specific human being who can be held personally accountable for the accuracy of the application and the entity’s ongoing tax compliance.
The responsible party is the person who ultimately owns or controls the entity, or who exercises ultimate effective control. For a single-member LLC it is the owner. For a multi-member LLC it is typically the managing member or the highest-percentage member. For a corporation it is usually the president or principal shareholder. For a partnership it is typically the general partner.
If you have a layered international structure where a foreign holding company sits above the U.S. entity, you still pick a human from that structure: the CEO of the parent, the director, the executive who actually signs decisions. That individual becomes the responsible party for U.S. EIN purposes, even if they are not the ultimate equity owner. Make sure their full legal name, date of birth, and passport details match what you provide on the form, because the IRS may verify these during a phone call.
Step 4: Handle Line 7b Correctly (the “Foreign” or “N/A” Entry)
Line 7b is the line that trips up the most cross-border applicants and causes more avoidable rejections than any other field. It asks for the responsible party’s SSN, ITIN, or existing EIN. If your responsible party has none of these and is ineligible to obtain them, the correct entry is the literal word “Foreign” or “N/A”.
This is not a placeholder, not an abbreviation, not a typo workaround. You write “Foreign” or “N/A” exactly as shown. The IRS instructions are explicit: “Enter ‘foreign’ or N/A on line 7b if the responsible party doesn’t have and is ineligible to obtain an SSN or ITIN. An entry is required.” Leaving Line 7b blank causes rejection. Entering zeros, dashes, all-nines, or a foreign tax number causes rejection.
This entry signals to the IRS database that your responsible party is a foreign national without a U.S. tax identification number. That is a normal, valid, and routine situation in the international EIN pipeline. It does not delay your application, raise red flags, or trigger any extra scrutiny. It is exactly what the IRS expects to see from a Cape Town, London, Mumbai, or Berlin applicant.
Step 5: Pick the Right Entity Classification on Line 9a
Line 9a is where you tell the IRS what kind of entity you are, and it drives how your business is taxed federally. Pick wrong and you will spend the next two years untangling tax classification mistakes. The boxes that matter for international ecommerce sellers:
- Sole proprietor (SSN) — rarely appropriate for organized foreign entities, and requires an SSN. Skip this.
- Partnership — for multi-member LLCs and partnerships taxed as partnerships.
- Corporation — for C corps and S corps. Enter the corporate form number on Line 9b (1120 for C corp, 1120-S for S corp).
- Other — the right answer for foreign-owned single-member LLCs and disregarded entities.
If you are a foreign individual who owns 100% of a U.S. single-member LLC (the most common cross-border structure we set up for our clients), check “Other” on Line 9a and write “Disregarded entity” in the space provided. By default, the IRS treats a single-member LLC as a disregarded entity, meaning the LLC itself does not file its own income tax return; the activity flows up to you.
If that same single-member LLC has any reportable transactions with related foreign parties (which includes, for nearly every cross-border seller, paying yourself, lending money in or out, or transferring goods between the LLC and your home-country entity), you must instead write “Foreign-owned U.S. disregarded entity-Form 5472”. This triggers an annual Form 5472 filing attached to a pro-forma Form 1120, due each April. Missing this filing carries a $25,000 minimum penalty, which is why we strongly recommend professional help with this step.
Step 6: Choose Your Filing Channel — Phone, Fax, or Mail
The IRS provides three application channels for foreign applicants. They differ in speed, cost, and confirmation:
| Channel | Contact | Hours | Processing Time |
|---|---|---|---|
| Phone (international line) | +1 267-941-1099 | Mon-Fri, 6:00 a.m.-11:00 p.m. ET | Same call |
| Fax (from outside the U.S.) | +1 304-707-9471 | 24/7 | ~4 business days |
| Fax (from inside the U.S.) | +1 855-215-1627 | 24/7 | ~4 business days |
| IRS, Attn: EIN International Operation, Cincinnati, OH 45999, USA | N/A | 4-6 weeks |
The phone line is by far the fastest. The IRS agent issues your EIN verbally during the call. The fax channel is the best second option if you cannot or would rather not call. Mail is the slowest and offers no real advantage unless your other options are blocked.
The international phone line (267-941-1099) is not toll-free, so use Skype, Google Voice, or a similar VoIP service to keep international calling costs manageable. The IRS Business and Specialty Tax Line for general inquiries and 147C requests is 1-800-829-4933, which operates Monday through Friday, 7:00 a.m. to 7:00 p.m. local time for the caller.
How to Fill in Form SS-4 Line-by-Line as a Foreign Entity
| Line | Field | What a Foreign Applicant Enters |
|---|---|---|
| 1 | Legal name of entity | Exact legal name from formation documents, including suffixes (Ltd, GmbH, Pty, B.V., Inc.) |
| 2 | Trade name (DBA) | Only if you trade under a name different from Line 1; otherwise leave blank |
| 3 | Executor / “Care of” name | Usually blank; complete only for trusts, estates, or correspondence directed to a specific agent |
| 4a-4b | Mailing address | Your foreign address. Full country name spelled out: “United Kingdom”, “South Africa”, “Germany”, “India” |
| 5a-5b | Physical street address | Actual business location (home office, warehouse, co-working address). No P.O. boxes |
| 6 | County and state | “N/A” if your business is entirely outside the U.S., or “Foreign: South Africa, Western Cape” |
| 7a | Responsible party name | Full legal name of the natural person who controls the entity, exactly as on their passport |
| 7b | Responsible party SSN/ITIN/EIN | “Foreign” or “N/A” if no SSN or ITIN. This is the critical line. |
| 8a | Is the entity an LLC? | Yes for U.S. LLCs and foreign LLC equivalents; No otherwise |
| 8b | Number of LLC members | 1 for single-member, otherwise the actual count |
| 8c | LLC organized in the U.S.? | Yes for Wyoming/Delaware/etc. LLCs; No for foreign LLCs |
| 9a | Type of entity | For foreign-owned single-member LLC: “Other” with “Disregarded entity” or “Foreign-owned U.S. disregarded entity-Form 5472” |
| 9b | State / foreign country of formation | Full state name (Wyoming, Delaware) or full country name |
| 10 | Reason for applying | Usually “Started new business” with “Electronic retail business” or “Banking purpose”. Never “N/A”. |
| 11 | Date business started | MM/DD/YYYY format. The date you began or will begin U.S. sales |
| 12 | Closing month of accounting year | December for calendar year; otherwise your fiscal year-end month |
| 13-15 | Employee info | “N/A” if no U.S. employees |
| 16 | Principal business activity | “Retail trade” or “Other” |
| 17 | Specific activity description | “Electronic retail sales of [product category]” — NAICS code 454110 |
| 18 | Prior EIN? | No, unless your entity has previously held an EIN |
Processing Times: Phone vs Fax vs Mail
Phone (267-941-1099): Same call. The IRS agent issues your EIN verbally during the conversation, usually within 20 to 40 minutes from when you connect. You write it on the top right of your Form SS-4, sign and date the form, and keep it. The CP 575 confirmation letter follows by mail in four to six weeks.
Fax (304-707-9471 from outside the U.S., 855-215-1627 from inside): Approximately four business days. The IRS Fax-TIN program runs 24/7, so you can send the form any time, and the IRS faxes your EIN back to the return number on your cover sheet. Use an eFax service with a U.S. fax number for the most reliable round-trip, since some international fax services have delivery issues with the IRS systems.
Mail (Cincinnati, OH 45999): Four to six weeks from when the IRS receives your envelope. International mail from South Africa, the UK, the EU, India, or Australia adds another 7 to 14 days of transit time, so plan for eight to ten weeks end to end. For sellers who need their EIN to launch on a marketplace, mail is almost never the right choice.
For phone applications, call early. The 6:00 a.m. Eastern opening converts to 11:00 a.m. in Cape Town and London, 12:00 p.m. across continental Europe, and 4:30 p.m. in India. Tuesday through Thursday calls tend to have shorter waits than Monday or Friday.
Common Rejection Reasons (and How to Avoid Them)
EIN applications from foreign entities are rejected for a small, predictable set of reasons. Knowing them in advance saves weeks of rework.
1. Legal name mismatch. The number-one cause of rejection. The name on Line 1 must match your formation documents character for character. “ABC Trading Company Ltd” rejected because the Articles read “ABC Trading Co. Ltd”. Print your formation documents and copy the name letter by letter.
2. Line 7b left blank or filled with placeholder numbers. Write the literal word “Foreign” or “N/A”. Not zeros, not dashes, not a passport number, not your home-country tax ID.
3. Entity listed as the responsible party. The responsible party must be a natural human person. Holding companies, parent corporations, and trusts cannot fill this role. Pick a human.
4. Wrong entity classification on Line 9a. Selecting “Sole proprietor” when you have an LLC, or missing the “Foreign-owned U.S. disregarded entity-Form 5472” notation when it applies, causes downstream tax filing problems even if the EIN itself issues.
5. Duplicate applications. Submitting the same application by phone and fax simultaneously, or resubmitting because you were impatient, can trigger duplicate EIN issuance and create permanent confusion in IRS records. Apply once, wait the stated processing time, and only then call to check status.
6. Foreign address improperly formatted. Spell out the country name fully. “UK” gets rejected; “United Kingdom” goes through. The IRS database does not recognize country code abbreviations.
What to Do With Your EIN Once You Have It
The moment you have your EIN, write it down in three places: your Form SS-4, a secure password manager, and a permanent business records folder. Then move quickly on the downstream steps it unlocks.
Request a Form 147C verification letter. Call 1-800-829-4933 and ask the IRS to fax you a 147C letter. This is the legal equivalent of the CP 575 confirmation letter and arrives the same day on the call. Because the IRS only issues the CP 575 once and international mail loss is real, the 147C is your insurance policy.
Open your U.S. bank or fintech account. Mercury, Wise Business, Relay, and Payoneer all accept the EIN and 147C as proof of federal tax registration for foreign-owned entities. Most U.S. brick-and-mortar banks still require an in-person visit, which is why most cross-border sellers go fintech-first.
Complete your marketplace tax interview. If you sell on Amazon, your W-8BEN-E and tax interview both require the EIN. The same goes for Stripe Atlas accounts, Shopify Payments for U.S. dollars, and TikTok Shop seller verification.
Register for state sales tax. Every state sales tax registration form has an EIN field. The EIN is also the link between your federal return and your state filings, so getting it before you trip a state’s economic nexus threshold matters. See our guide to whether non-US sellers need U.S. sales tax for the nexus rules and our Amazon FBA sales tax guide for international sellers for marketplace-specific rules.
Done-For-You: How We Handle EIN Acquisition for Cross-Border Sellers
Most service options in this space hand you a software platform, a template form, or a webinar and tell you to do it yourself. That works if you have time to learn IRS procedure, sit on hold to the international line, and troubleshoot rejections when they come. For most of the founders we work with, time spent on a 90-minute hold to the IRS at 6:00 a.m. Eastern is time not spent on selling.
Sales Tax Compliance USA is built differently. Our team of cross-border accountants, led by Paul le Roux (CA(SA), ICAEW), prepares and files your Form SS-4 end to end. We confirm your entity classification, complete every line correctly the first time, file via the fastest available channel for your situation, secure the CP 575 and a 147C backup, and hand you everything you need to open bank accounts, complete marketplace tax interviews, and register for state sales tax. One payment, one team, one inbox. We do it for you.
Frequently Asked Questions
1. Do I need an ITIN before I can apply for an EIN as a foreign person?
No. This is the single most common misconception, and following it can cost you three to four months of delay. The IRS Internal Revenue Manual states explicitly that foreign individuals are not required to have an ITIN in order to receive an EIN. The EIN belongs to your business entity. The ITIN belongs to you personally for filing a U.S. individual tax return. If your responsible party has no SSN or ITIN, you simply enter the literal word “Foreign” or “N/A” on Line 7b of Form SS-4, and the application proceeds normally. Apply for the EIN first. Only file Form W-7 for an ITIN later if your specific facts require it — for example, if you personally need to file a U.S. individual return to claim a treaty benefit or report U.S.-source income. For most cross-border ecommerce sellers operating through an LLC or corporation, an ITIN is never needed at all.
2. How much does the IRS charge for an EIN?
Nothing. The IRS charges no fee for an EIN application, regardless of your country, citizenship, entity type, or application channel. Phone, fax, and mail are all free. If a website is asking you to pay the IRS for an EIN, that is a third-party service charging for the work of preparing and filing the application, not an IRS fee. The only direct costs you might incur are international calling charges if you phone the 267-941-1099 line from outside the U.S. (which a VoIP service like Skype or Google Voice keeps to a few dollars), or international postage if you mail Form SS-4 to Cincinnati. Be wary of websites that advertise “IRS EIN application” with high fees but no advisory work behind them. You are paying for either professional help or nothing of value.
3. Can I apply for an EIN before my LLC is officially formed?
Yes, you can, but in practice we recommend forming the entity first. The IRS will accept Form SS-4 based on the entity you are forming, but the EIN application asks for the legal name exactly as it appears on your formation documents. If the formation paperwork is still in flux (the state has not yet issued your Articles of Organization, or a name change is pending), you risk filing the EIN under a name that ultimately differs from your registered entity, which creates a permanent mismatch in IRS records. The cleanest sequence is: form the LLC with the state, receive the stamped Articles of Organization (typically within a few business days for Wyoming or Delaware), copy the exact legal name onto Form SS-4, then apply for the EIN. The entire start-to-finish timeline from state formation to EIN in hand is usually under two weeks if you use the phone channel.
4. What is Form 5472 and when do foreign-owned single-member LLCs need to file it?
Form 5472 is an information return that reports transactions between a U.S. business and its related foreign parties. If you are a foreign individual who owns 100% of a U.S. single-member LLC, and that LLC has any reportable transactions with you, your home-country company, or other related foreign parties, you must file Form 5472 attached to a pro-forma Form 1120 each year, due in mid-April. Reportable transactions are very broadly defined and include funding the LLC, paying yourself, moving inventory in or out, paying for services, or making loans. Almost every cross-border seller running products through a U.S. LLC will have reportable transactions. This is why, on Form SS-4 Line 9a, foreign-owned single-member LLCs should generally check “Other” and write “Foreign-owned U.S. disregarded entity-Form 5472”. The minimum penalty for missing Form 5472 is $25,000 per year per entity, so this is not a filing to overlook.
5. How long does the EIN phone application actually take in real time?
The call itself usually runs 20 to 40 minutes from the time you connect to a live agent, plus whatever you spend on hold. Hold times vary widely depending on when you call. If you dial the 267-941-1099 line at 6:00 a.m. Eastern (which is 11:00 a.m. in South Africa and London, 4:30 p.m. in India), you typically get through within 10 to 15 minutes. Mid-morning U.S. time (10:00 a.m. to 12:00 p.m. ET) can stretch hold times to over an hour. Tuesday through Thursday calls tend to be faster than Monday or Friday. The agent works through every line of your completed Form SS-4 with you, verifies the responsible party’s identity, and issues your EIN verbally on the same call. Have your form, your passport, your formation documents, and a pen ready when you dial.
6. Can I use a foreign address on Form SS-4 or do I need a U.S. address?
You can absolutely use a foreign address. The IRS explicitly permits foreign mailing addresses on Form SS-4 for international applicants, and you do not need a U.S. mailing address, U.S. phone number, or U.S. registered agent address to obtain an EIN. On Lines 4a-4b, enter your foreign mailing address with the full country name spelled out (“South Africa”, not “RSA”; “United Kingdom”, not “UK”; “Germany”, not “DE”). On Lines 5a-5b, enter your foreign physical address if it differs from your mailing address. The IRS will mail your CP 575 confirmation letter to whatever address you provide. That said, for downstream U.S. business operations (state sales tax registrations, bank accounts, marketplace verifications), a U.S. business mailing address — typically provided by your registered agent — is often required. The EIN application itself is not where you need to solve that problem. For the broader question of operating without a U.S. address, see our guide to U.S. sales tax registration without a U.S. address.
7. What if I lose my CP 575 confirmation letter in international mail?
It happens more often than you would think — international mail from Cincinnati to Cape Town, Mumbai, or rural UK addresses gets lost or delayed regularly. The IRS will not reissue a CP 575. Ever. There is only one original. Instead, you request a Form 147C EIN Verification Letter. The 147C is the legal equivalent of the CP 575 and serves every downstream purpose: opening bank accounts, completing marketplace tax interviews, registering for state sales tax. To request it, call the IRS Business and Specialty Tax Line at 1-800-829-4933 (Monday to Friday, 7:00 a.m. to 7:00 p.m. local time). The agent verifies your identity, then either faxes you the 147C on the same call (the fastest option — use an eFax service with a U.S. number) or mails it to your address on file. As a routine matter, we request a 147C for every client immediately after their EIN is issued, well before the CP 575 has even left Cincinnati. That digital backup eliminates the cross-border mail risk entirely.
8. Can a non-US person be the responsible party for a U.S. LLC's EIN?
Yes. The responsible party requirement is that they be a natural person (a human, not an entity), not that they be a U.S. citizen or resident. A South African, UK, Indian, German, Australian, or Canadian individual is perfectly eligible to be the responsible party for a U.S. LLC. The only operational requirement is that you handle Line 7b correctly by entering “Foreign” or “N/A” when the responsible party has no SSN or ITIN. You will need to provide your full legal name (exactly as it appears on your passport), date of birth, and possibly passport number for IRS identity verification, particularly on phone applications. There is no requirement to ever travel to the United States, hold a U.S. visa, or have any U.S. physical presence. Millions of foreign individuals have been issued EINs for U.S. entities under this exact pathway.
The Bottom Line
An EIN for a foreign entity is far more accessible than the U.S.-domestic-focused internet would have you believe. The IRS has built a dedicated international pathway with its own phone line (267-941-1099), its own fax numbers (304-707-9471 from outside the U.S., 855-215-1627 from inside), and its own form completion conventions designed specifically for applicants who do not hold a Social Security Number. The fastest channel — phone — issues your EIN verbally on the same call, free of charge, usually inside an hour from when you dial.
The mistakes that block people are predictable: applying through the closed online channel instead of the international pathway, leaving Line 7b blank instead of writing “Foreign”, listing a parent company instead of a human as the responsible party, mistyping the legal name, or thinking they need an ITIN first. Get those right and the process is mechanical.
For South African, UK, EU, Indian, Australian, and Canadian ecommerce sellers, the EIN is the first step in a longer compliance chain that runs through U.S. bank accounts, marketplace and payment-processor W-8 tax interviews, state sales tax registrations, and (for most foreign-owned single-member LLCs) annual Form 5472 filings. We handle every step of that chain end to end for our clients at Sales Tax Compliance USA. If you would rather hand it to a cross-border accounting team than spend your Monday morning on hold to the IRS, book a free consultation and we will take it from here.
