Getting an EIN Without a Social Security Number

Your LLC exists, the state confirmation is in your inbox, and now you need the one number that turns a shell company into an operating business: an EIN, the Employer Identification Number. It's the federal tax ID, the company's equivalent of a social security number, and nothing downstream works without it. No bank account, no Stripe, no Wise, no tax filing. Every service you're about to sign up for will ask for it.

And here's where founders without a US social security number hit a wall of bad information. Search around and you'll be told the online EIN application requires an SSN (true), and — repeated confidently across dozens of guides — that the IRS discontinued the fax channel, leaving you no way in (false). That myth has sent people scrambling for expensive workarounds they don't need. Let's clear it, then walk the actual process, because the whole thing comes down to filling out one form correctly.

The fax-is-dead myth, corrected

The claim goes: "As of recently, the IRS retired fax-based EIN applications — phone or nothing." It's wrong, and it matters, because fax is one of only two realistic routes for a founder without an SSN. The IRS's own guidance on how to apply for an EIN still lists fax as a valid submission channel. It was never discontinued. People conflate "the online tool needs an SSN" with "the only channel is online," and the fax myth grows from there.

Without an SSN you lose the online instant-issuance tool — but you keep the phone and you keep the fax. Both are fully valid, and one of them gives you the number on the same call.

Here are the routes that actually work when you don't have an SSN or ITIN:

The phone route is fastest — you hang up with an EIN in hand. The international fax route is the fallback if you'd rather not do a live, all-English call with an IRS agent. Mail exists but four weeks is a long time to wait for something you can get in twenty minutes. Most people should aim for the phone and keep fax as the backup.

The form is the whole game: Form SS-4

Every route submits the same document — Form SS-4, the EIN application. Whether you're reading answers to an agent over the phone or faxing the sheet, the form is what gets approved or bounced. Four fields cause virtually every rejection, so prep them deliberately.

Line 7b — the SSN/ITIN field. This is the one that stops people cold on the phone. Line 7b asks for the Responsible Party's SSN or ITIN. You don't have one. Write "foreign" in this field — do not leave it blank. A blank Line 7b reads as an incomplete form and the agent can't proceed; the literal word "foreign" tells the IRS you're a non-US person applying without a US tax ID, which is a valid, expected case. This single word is the difference between an approved application and a confused agent telling you to call back.

Line 11 — the formation date. This must match the date on your state formation certificate exactly. Not the day you started the project, not the day you decided to incorporate — the date the state stamped your LLC into existence. If your Articles of Organization say the company formed on one day and you tell the IRS a different day, even by 24 hours, the application gets rejected for mismatch. Pull up the state confirmation and read the date straight off it.

Line 15 — the business description. Line 15 asks what your business actually does, and vague answers invite follow-up questions you don't want during a phone application. "Consulting" is the classic trap — it's so generic the agent will probe further. Be specific about what and to whom. Strong descriptions read like:

• SaaS: "We develop and sell software tools to small businesses in the US."
• E-commerce: "We sell consumer goods to US customers through online marketplaces."

The pattern is concrete product plus concrete customer. Specificity here isn't just about approval — it's the same description your bank will later want, so getting it sharp now pays off twice.

Responsible Party — a natural person, never the company. The form asks for a Responsible Party, and this must be a human being — you, by name. A common mistake is entering the company's own name here, which is invalid: an entity can't be its own responsible party. Put your legal name. The IRS wants to know which actual person controls the company, and for a solo founder that person is you.

Running the phone application

If you take the phone route, a little logistics prep saves you a wasted call:

• Mind the hours. The international EIN line operates on US Eastern time, Monday through Friday, roughly 6:00 a.m. to 11:00 p.m. If you're calling from another timezone, do the math before you dial — the line simply won't answer outside those windows.
• Have the completed SS-4 in front of you. The agent walks the form line by line and you read your answers back. Fill it out fully beforehand so you're never improvising, especially on Lines 7b, 11, and 15.
• Expect an all-English call. The conversation is in English, it's a government call, and the agent moves briskly. If that's uncomfortable, the international fax route removes the live pressure entirely.
• Write the number down immediately. On a successful call the agent reads your new EIN aloud once. Capture it on the spot — you'll need it within the hour for the next step.

If the live call feels like too much, fax the SS-4 to the international number and wait your ~4 business days. It's slower, but it's the same form, the same four critical fields, and no one talking back at you in real time. Either way, the form — not the channel — is what determines success.

What this unlocks, and what to sidestep

An EIN is the key that fits the next several locks. With it in hand you can open a US business bank account, register for Stripe or Wise Business, and file the tax forms your LLC owes. Without it, the company is inert. So treat the SS-4 as the highest-leverage twenty minutes in the whole formation process — the fields above are genuinely all that stand between you and the number.

Two things to carry forward. First, ignore anyone who tells you fax is dead or that you need a paid third-party service to get an EIN without an SSN — the phone and fax channels are free and open, and the IRS's own pages confirm it. Second, the specific business description you write on Line 15 is worth getting genuinely good, because it reappears on your bank application, where a vague answer is one of the top reasons accounts get declined.

The EIN gets you a working company. The next challenge is keeping it compliant — and that's where the numbers stop being $100 fees and start being five-figure penalties most guides never mention.
