How to Get an EIN Without an SSN (2026 Guide)
Forming the company is the easy part. For most non-residents, the EIN is where things stall — because the fast online route is closed to anyone without a US Social Security Number. Here is the route that actually works, how long it really takes, and what makes an application fail.
Why non-residents get stuck at the EIN step
An EIN — Employer Identification Number — is the federal tax ID for your company, the business equivalent of a personal Social Security Number. You need it to open a US bank account, run payroll, file federal returns, and pass verification on marketplaces like Amazon. Forming the LLC itself takes only a passport and a few business days; no SSN, ITIN, or visa is required to own a US company. The EIN is the first place the process trips up, because the IRS's quick self-service tool assumes something a foreign founder does not have.
The IRS online EIN assistant issues a number instantly — but only to applicants who already hold an SSN or ITIN to enter as the "responsible party." With no such number, that door is simply closed to you. That is not a bug or a workaround waiting to be found; it is how the system is built. The correct path is a paper form, and knowing that up front saves weeks of hunting for an online shortcut that will never appear.
The Form SS-4 route: the only door open to you
The application for an EIN is Form SS-4. A non-resident with no SSN or ITIN files it directly with the IRS rather than through the website. On the form you name the entity, its US mailing address, the responsible party (typically you, the owner), and the reason you are applying. Where the form asks for the responsible party's SSN or ITIN, a foreign individual who has neither writes "Foreign" in that field — this is the specific, expected answer for an applicant abroad, and it is what unlocks EIN issuance without a US personal tax number.
Because you are filing on paper, accuracy matters far more than it would online, where the system catches obvious errors as you type. A paper SS-4 that contradicts itself, names the wrong responsible party, or leaves a required box blank does not bounce back with a helpful message — it goes into a queue and comes back weeks later as a rejection or a request for more information.
Fax vs mail: the timing difference
Once the SS-4 is complete, it reaches the IRS one of two ways, and the choice affects your timeline more than anything else. Fax is the faster channel: the IRS processes faxed international SS-4 applications and faxes the EIN back, typically within a couple of weeks. Mail is the slower channel and can take considerably longer once international postal time is added to IRS processing. As a practical matter, plan on roughly 10 to 14 days or more from a clean fax submission to an issued number, and longer by mail — these are ranges, not promises, because IRS throughput is outside anyone's control and varies through the year (as of 2026).
The honest takeaway is to build this waiting period into your plan. If your goal is to be selling by a certain date, the EIN — not the company formation — is usually the critical-path item, and it cannot be rushed by paying more. It can only be shortened by submitting a correct application through the faster channel the first time.
What the IRS actually requires
The requirements are narrower than the anxiety around them suggests. You need a formed US entity (or, in some cases, you can apply as it is being formed), a responsible party the IRS can identify, and a US mailing address for correspondence. You do not need a US Social Security Number, a US visa, US residency, or a US phone number to be issued an EIN. The "Foreign" entry in place of an SSN or ITIN is the mechanism the IRS provides precisely so that foreign owners can comply.
One point worth internalizing: the EIN is tied to a responsible party, and that should be a real person who genuinely controls the company — normally you. Naming someone else for convenience, or letting a service insert its own details, creates a mismatch you will have to untangle later, especially when a bank or marketplace cross-checks who controls the entity.
Common reasons an SS-4 gets rejected or delayed
Most delays trace back to a handful of avoidable mistakes:
- Inconsistent names. The entity name on the SS-4 must match the name on your formation documents exactly — punctuation, "LLC" suffix, and all.
- A responsible party the IRS can't reconcile. Wrong person, wrong country, or a field left blank where "Foreign" belonged.
- Applying before the entity exists in a way the IRS can verify, or with a state filing that hasn't finalized.
- An unreliable return path. A fax number that fails or a foreign address that stalls correspondence turns a two-week wait into a lost application.
- Duplicate applications. Sending the SS-4 twice because the first felt slow can create conflicting records and set you back further.
None of these are exotic — they are ordinary paperwork errors that a paper process punishes more harshly than an online one. Getting the number is rarely the hard part; getting a clean number, tied to the right party, on the first attempt is.
Why the EIN has to be right the first time
The EIN is not a box to tick and forget. It flows into everything downstream. You cannot file Form 5472 — the annual return most foreign-owned US LLCs owe — without it, so an EIN problem quietly becomes a compliance problem. And the exact name and details attached to your EIN have to line up with your bank records and your marketplace account, or verification stalls. This is why founders who cut corners at the EIN stage often hit a wall later at Amazon seller verification, where every record is expected to match. An EIN issued to the wrong responsible party, or under a slightly-off entity name, is a problem you carry forward.
How we handle it
We prepare and file the SS-4 for foreign owners, name the responsible party correctly, submit through the faster channel, and monitor the application until the EIN is in hand — then make sure the number matches the records you'll use to open a bank account and pass marketplace checks. It is part of our US market-entry work and our e-commerce and Amazon practice, so the EIN is set up in the context of everything that depends on it, not in isolation. If you're forming a US company from abroad and want the EIN done right the first time, talk to us before you file.
