How to get an EIN without an SSN

By the Zipple team · Updated October 28, 2026

An EIN is your company's federal tax number. You need it for a bank account, Stripe, payroll and every tax return. Founders outside the US can get one without a Social Security number.

Why the online application doesn't work

The IRS online EIN application asks for the SSN or ITIN of the company's "responsible party". If that person doesn't have one, the online tool isn't an option, and the IRS says international applicants can't use it. You apply on Form SS-4 instead.

Three ways to apply

MethodHowTiming
PhoneCall the IRS international line at 267-941-1099 (not toll-free), Monday to Friday, 6 a.m. to 11 p.m. Eastern. Have a completed SS-4 in front of you.EIN given during the call
FaxFax the signed SS-4 to 304-707-9471 from outside the US.Usually about 4 business days
MailInternal Revenue Service, Attn: EIN International Operation, Cincinnati, OH 45999.Allow 4 to 5 weeks

Phone numbers and fax lines change from time to time. Check the current Form SS-4 instructions on irs.gov before you call or fax.

Filling in Form SS-4

Order matters: form the company first, then apply for the EIN. The name on the SS-4 must match the state filing exactly, or the bank will ask questions later.

After you get it

The IRS sends a confirmation letter, CP 575, by mail. Banks and payment processors often ask for it. If you lose it, the IRS can send a replacement letter (147C) when you call the business line.
