Here’s the key fact up front: without a U.S. Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), you cannot use the IRS online EIN application. Foreign founders must file IRS Form SS-4 by fax or mail — typically a 4 to 6 week wait. The good news: the EIN itself is completely free, and once you understand the process, it’s just paperwork and patience.

If you’re a non-U.S. resident forming a U.S. LLC, the EIN step is where most people get stuck: the online application rejects you, shady sites try to charge you for something the IRS gives away free, and conflicting blog posts leave you unsure what to put on the form. This guide covers the whole process — what an EIN is, why you need one, how to fill out Form SS-4, and what to do during the 4–6 week wait.

What Is an EIN (and Why Your LLC Can’t Function Without One)

An EIN — Employer Identification Number — is a nine-digit tax ID the IRS assigns to your business (formatted XX-XXXXXXX). Think of it as a Social Security Number for your company. Despite the name, you need one even if you never hire anyone.

  • Opening a U.S. business bank account. Every U.S. bank — and most fintech alternatives like Mercury or Wise — requires an EIN before they’ll open a business account for your LLC.
  • Filing U.S. taxes. A foreign-owned single-member LLC must file Form 5472 with a pro forma Form 1120 every year. You can’t file without an EIN, and the penalty for skipping that filing is a brutal $25,000.
  • Hiring employees or contractors in the U.S. If you ever bring on U.S.-based help, you’ll need the EIN for payroll tax reporting.
  • Building business credit and working with payment processors. Stripe, PayPal Business, and similar platforms typically ask for an EIN during verification.

In short: your LLC legally exists after state approval, but it can’t really do anything — bank, get paid, stay tax-compliant — until the EIN arrives.

Who Needs an EIN?

Every foreign-owned U.S. LLC — yes, including single-member LLCs

There’s a persistent myth that a single-member LLC with no employees doesn’t need an EIN. For foreign-owned LLCs, it’s not a real option. You need an EIN to:

  1. Open any U.S. business bank account
  2. File the mandatory annual Form 5472 / pro forma 1120
  3. Be taken seriously by payment processors and business partners

If you’re a non-resident founder, just assume: you need an EIN. Full stop.

What about multi-member LLCs or corporations?

Multi-member LLCs (taxed as partnerships by default) and corporations also require an EIN. The process in this guide works the same — only a few lines on Form SS-4 differ.

Why Foreigners Can’t Use the IRS Online EIN Application

The IRS online EIN application is instant — U.S. residents get their number in minutes. So why can’t you just use it?

Because the online system requires the “responsible party” (the person who controls the business — that’s you) to have a valid SSN or ITIN, validated in real time. No SSN or ITIN, no online application. There’s no workaround and no alternative portal.

This is also where scams thrive. You’ll find websites offering to “get your EIN online in 24 hours” for $50–$300. They’re either faxing the same Form SS-4 you’d fax yourself (and pocketing the fee), or doing something shady you don’t want attached to your business. The EIN itself is always free from the IRS. Never pay the IRS for an EIN, and never — under any circumstances — use someone else’s SSN or a fake SSN on a federal tax form. That’s a serious federal crime.

Your legitimate options as a foreigner are exactly two: fax Form SS-4 to the IRS, or mail it. That’s it. Let’s walk through how.

What You Need Before You Apply

Don’t start the EIN application until these are in place:

  1. Your LLC must already be formed. The IRS needs the LLC’s exact legal name as approved by the state — apply with a mismatched name and you’ll create a bureaucratic headache. File your Articles of Organization first, wait for state approval, then apply.
  2. Your information as the responsible party. Your full legal name (as on your passport) and your foreign address. No U.S. address needed.
  3. A fax number or mailing address where the IRS can reach you. The IRS sends the EIN confirmation letter (CP 575) by fax or mail — never by email. Free online fax services work fine for receiving.
  4. Decide on a third-party designee (optional). Form SS-4 lets you authorize someone — like a formation service — to receive the EIN on your behalf.

How to Get an EIN as a Foreigner: Step-by-Step

Here’s the full process, start to finish.

Step 1: Download the current Form SS-4 and its instructions

Get the current Form SS-4 (Application for Employer Identification Number) and its instructions from IRS.gov. The instructions contain the current fax number and mailing address for international applicants — these change, so never rely on a fax number from an old blog post. Always verify on IRS.gov.

Step 2: Fill out Form SS-4 — line by line

Below is a plain-English walkthrough of the key lines. This is general guidance, not tax advice — always double-check against the current IRS instructions, which are updated periodically.

  • Line 1 – Legal name of entity: Your LLC’s exact legal name as approved by the state. Copy it precisely from your Articles of Organization.
  • Line 2 – Trade name: Only if you operate under a DBA (“doing business as”) name. Most new LLCs leave this blank.
  • Line 4a–4b – Mailing address: Where the IRS should send correspondence. Your foreign address is fine — a U.S. address is not required.
  • Line 6 – County and state: The U.S. state where your LLC is formed.
  • Line 7a–7b – Responsible party: That’s you (or whoever controls the business). Enter your full legal name as on your passport. For the SSN/ITIN/EIN field, follow the current instructions for applicants without a U.S. tax ID — the exact entry the IRS expects has been updated over the years, so verify on IRS.gov.
  • Lines 8a–8c – LLC information: Indicate the entity is an LLC, the number of members, and the state of organization.
  • Line 9a – Type of entity: Check the box matching your tax classification (e.g., disregarded entity for a single-member LLC).
  • Line 10 – Reason for applying: Typically “started new business.”
  • Line 11 – Date business started: The date your LLC was legally formed.
  • Line 13 – Number of employees: Zero if you’re not hiring yet — be honest; you can update it later.
  • Third-party designee section: Optional. Complete this if you want someone else (like a formation service) to receive the EIN on your behalf.
  • Signature and date: Sign and date the form. An unsigned form will be rejected.

Take your time here. A sloppy or inconsistent form is the #1 cause of delays.

Step 3: Fax or mail the signed form

By fax: Send the completed, signed SS-4 to the IRS fax number in the current instructions for international applicants. Keep your fax transmission confirmation as proof of filing date.

By mail: Send the signed original to the address in the current SS-4 instructions for applicants outside the U.S., using trackable international postage.

Step 4: Wait — typically 4 to 6 weeks

Processing usually takes about 4 to 6 weeks, with mailed applications on the slower end. There’s no online tracking for fax/mail applications. The IRS will send your EIN confirmation letter (CP 575) by fax or mail.

Step 5: Safeguard your EIN confirmation letter

When the CP 575 arrives, save it like a passport. Banks often ask to see it, and replacing a lost letter is its own bureaucratic adventure. Keep a digital scan in at least two places.

Fax vs. Mail: Which Should You Choose?

Fax Mail
Typical processing ~4 weeks (sometimes faster) ~4–6 weeks
Proof of submission Fax transmission report Postal tracking receipt
Cost Free–cheap (online fax services) International postage
Risk Faxes can fail silently — confirm transmission Mail can be slow or lost — use tracking
Best for Most foreign founders If you can’t access a fax service

Our recommendation: fax if you can. It’s generally faster, you get a transmission confirmation, and free online fax tools make it easy. Just confirm the fax actually went through — a “transmission OK” report matters.

What to Do While You Wait (4–6 Weeks)

The waiting period is frustrating, but it’s not dead time:

  1. Draft your Operating Agreement. Banks and payment processors almost always ask for it. Get it signed and matching your LLC’s details.
  2. Set up business basics. Build your website, set up professional email, and organize your formation documents in one folder.
  3. Research banking options. Compare requirements for Mercury, Wise Business, Relay, and traditional banks, so you can apply the day your EIN arrives.
  4. Plan your tax calendar. Mark the annual Form 5472 + pro forma 1120 deadline and your state’s annual report due date. Missing the 5472 carries a $25,000 penalty — put it in your calendar now.
  5. Don’t try to shortcut the wait. Resist “expedited EIN” sellers — they’re either faxing the same form or running a scam.

Common Reasons EIN Applications Get Rejected or Delayed

Most delays are self-inflicted. Avoid these:

  • Name mismatch. The LLC name on Form SS-4 doesn’t exactly match state records. Copy it character-for-character from your approved Articles of Organization.
  • Applying before the LLC exists. If the state hasn’t approved your formation yet, wait — the IRS verifies the entity.
  • Missing signature or date. An unsigned SS-4 goes straight to the rejection pile.
  • Responsible-party line errors. The IRS has specific expectations for foreign applicants without an SSN/ITIN — follow the current instructions exactly.
  • Illegible faxes. Use a clean scan, not a phone photo of a crumpled page.
  • Outdated fax number or address. Always pull current contact details from the latest SS-4 instructions on IRS.gov.
  • Duplicate applications. Don’t refile just because you haven’t heard back — duplicates can create conflicting records. Wait the full processing window first.

If your application is rejected, the IRS will state the reason. Fix that specific issue and refile.

The Easier Route: Let a Formation Service Handle It

Let’s be honest: between forming the LLC in the right state, getting the SS-4 lines exactly right, finding a working fax solution, and waiting over a month with no tracking — the EIN process is the most annoying part of starting a U.S. business as a foreigner.

That’s why many non-resident founders hand the whole thing to a formation service. The service forms your LLC, completes and submits the SS-4 correctly as your authorized third-party designee, receives the EIN on your behalf, and delivers everything as a tidy package.

If you’d rather not wrestle with IRS fax forms, formation services like Registered Agents Inc handle the paperwork as part of formation ($100 + state fee), which includes your state filing, a domain name, a website, and a full year of registered agent service.

Whether you DIY or delegate, the important thing is that it gets done right — because everything downstream (banking, taxes, getting paid) depends on those nine digits.

FAQ: EIN for Foreigners

Is the EIN really free?

Yes. The IRS never charges for an EIN. Anyone charging you “for the EIN itself” is marking up a free government service. (Paying a service for their time to handle the paperwork is different — and legitimate.)

Can I get an EIN without an SSN or ITIN?

Yes — that’s what this guide covers. You can’t use the online application, but you can apply by faxing or mailing Form SS-4, following the current instructions for the responsible-party line.

How long does it take to get an EIN as a foreigner?

Typically 4 to 6 weeks from when the IRS receives your Form SS-4. Faxed applications tend to be faster; mailed ones slower. Plan your launch timeline around this.

Do I need a U.S. address to get an EIN?

No. Your foreign mailing address is fine on Form SS-4. (You do need a U.S. registered agent for the LLC itself — that’s a separate state-law requirement.)

Can I open a U.S. bank account without an EIN?

No — not a business account. Every U.S. bank and reputable fintech requires an EIN. That’s why the EIN is on your critical path.

What if I lose my EIN confirmation letter (CP 575)?

You can request a replacement (Form 147C letter) from the IRS, but it’s another slow process. Save the original in multiple places and skip the headache.

Should I get an ITIN just to apply for the EIN online?

Usually not worth it — the ITIN application (Form W-7) takes 6–11 weeks, longer than just faxing the SS-4. Only pursue an ITIN if you need one for other tax reasons.

Can a formation service get my EIN faster than I can?

They use the same IRS process, so IRS processing time is identical. The advantage is accuracy: they complete the SS-4 correctly and submit it as your authorized designee — eliminating the most common causes of delays (errors and refiles).

Conclusion: Your Next Steps

Getting an EIN as a foreigner without an SSN boils down to three things: form your LLC first, file Form SS-4 by fax or mail, and wait 4–6 weeks. The EIN is free and no U.S. address is required.

Your action plan:1. ✅ Form your LLC and get your approved Articles of Organization
2. ✅ Download the current Form SS-4 + instructions from IRS.gov
3. ✅ Fill it out carefully (or authorize someone to do it for you)
4. ✅ Fax it (preferred) or mail it with tracking
5. ✅ Use the waiting period to prepare your Operating Agreement and banking applications

And if you’d rather skip the paperwork entirely, Registered Agents Inc handles formation plus the EIN paperwork for $100 + state fee — state filing, domain, website, and a year of registered agent service included.
