How to Get an EIN Without an SSN (Foreign Founders)

Why does the online application reject foreign founders?

The IRS online EIN tool requires the responsible party, the person who owns or controls the entity, to enter a valid SSN or ITIN, and it verifies the name and number pair in real time. No number means no way through: the tool simply has no foreign path. That is a limitation of the website, not an eligibility rule. Founders outside the U.S. are fully entitled to an EIN for their U.S. LLC or corporation, and a faxed or mailed SS-4 is how the IRS takes those applications.

The 3 myths that cost founders weeks

• “Get an ITIN first.” Backwards, and expensively so. You do not need an ITIN for an EIN, ITIN applications take weeks, and they require a tax filing reason. Founders who follow this advice stall their bank account and Stripe onboarding for a month chasing a number their EIN never needed.
• “You need a U.S. address.” Form SS-4 accepts a foreign mailing address. A U.S. address (commonly your registered agent’s) is fine if you have one, but its absence blocks nothing.
• “You must be a U.S. resident.” Line 7b of the SS-4 exists precisely for you: where the form asks for the responsible party’s SSN or ITIN, a foreign responsible party writes “Foreign.” That single word is the whole mechanism.

The SS-4, line by line: what foreign founders get wrong

• Line 1 (legal name): exactly as registered with the state, including the “LLC” or “Inc.” suffix and punctuation. Mismatches here cause silent delays.
• Lines 4a and 4b (mailing address): U.S. or foreign, both accepted. This is where the IRS sends correspondence, so use an address someone actually monitors.
• Line 7a (responsible party name): passport spelling of the individual who controls the entity. It must be a person, not your other company.
• Line 7b: write “Foreign”. Do not leave it blank (that is an incomplete form rejection) and do not invent a number.
• Line 9a (entity type): for a single member LLC owned by a foreign individual, this interacts with tax classification in ways worth getting right the first time. “Other” plus “disregarded entity” versus a corporation election changes your future filing obligations.
• Line 10 (reason): “Started new business” with a one line description is the clean answer. “Banking purposes” is also valid for holding structures.
• Signature: the responsible party (or a designated third party; that is what the Third Party Designee block is for) must sign. Unsigned faxes bounce.

Route 1: Fax (about 11 business days)

1. Complete the SS-4 as above.
2. Fax it to the line for the business’s location, not the owner’s: 855-641-6935 if the LLC’s principal place of business is in one of the 50 states or DC; with no residence, business or office in any state, 855-215-1627 from inside the U.S. or 304-707-9471 from outside it. And include a return fax number. That is how the EIN typically comes back in about 11 business days, sometimes longer. An online fax service works, and its inbound number is a perfectly good return line. Without a return fax, the answer goes to international postal mail and the wait becomes weeks.

Route 2: Phone, only for a company organized outside the U.S.

The IRS international line, 267-941-1099 (not toll free), runs Monday to Friday, 6 a.m. to 11 p.m. U.S. Eastern, and the IRS manual tells its agents to check first where the business was created or organized. A corporation or LLC organized in the United States is a domestic case, and the caller is told to apply by the other methods. So for a U.S. LLC with a foreign owner, the phone line is not a route; the fax is. Where the line does apply, to an entity organized abroad, the agent goes through the completed SS-4 and an authorized person can receive the EIN during the call.

What about mail?

Mailing the SS-4 to Internal Revenue Service, Attn: EIN Operation, Cincinnati, OH 45999 works but takes about four weeks plus international postage time. It is the route of last resort.

After the EIN: banks, Stripe, and the paper letter

• The number is usable immediately. Mercury, Relay, Wise Business, Stripe, and Amazon all accept a fresh EIN the day it is issued.
• Keep the faxed assignment notice. For phone and fax applicants that document plays the role of the CP 575 letter online applicants download, and platforms occasionally ask for it during verification.
• The mailed confirmation follows in 4 to 10 weeks to the address on line 4. It is a formality; nothing waits on it.

Quick answers

Can a non U.S. resident own a U.S. LLC at all?

Yes. There is no citizenship or residency requirement to own a U.S. LLC or corporation. S corps are the exception, since those require U.S. persons as shareholders. The EIN is the step that makes the entity financially operational.

Do I need to visit the U.S.?

No. Formation, the EIN, and most modern banking (Mercury, Wise, Relay) are fully remote. Traditional banks are the one thing that may want an in person visit.

How long does the whole process take from abroad?

For a U.S. LLC or corporation with a correctly prepared SS-4, fax is about 11 business days and mail about 4 weeks. The same-day phone route is only for a company organized outside the United States. The multi week horror stories almost always trace back to an incomplete form, a missing return fax number, or the ITIN first myth above.

Does the EIN create U.S. tax obligations?

The EIN itself does not; it is an identifier. What you owe depends on your entity type and activities. A foreign owned single member LLC has an annual Form 5472 information filing, for example. That is a question for a cross border tax professional, and having the EIN is prerequisite to nearly every answer.
