How to Get an EIN Without an SSN (2026 Guide)
Forming the company is often the easy part. For many non-residents, the EIN is where the timeline stretches because the IRS online route is not available when the applicant is outside its eligibility rules. International applicants can use the current phone, fax, or mail routes. Here is how those routes work and what commonly delays an application.
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. Banks, payroll providers, tax returns, and marketplaces commonly ask for it. A non-resident can own a US company without an SSN, ITIN, or visa, but formation timing, EIN processing, licensing, and banking are separate steps with separate requirements.
The IRS online EIN assistant is available only when its eligibility conditions are met, including a legal residence, principal place of business, or principal office or agency in the United States or a US territory and a valid taxpayer identification number for the responsible party. Applicants outside the online rules may use fax or mail. Telephone assignment is narrower: the IRS limits it to international applicants with no legal residence, principal place of business, or principal office or agency in the United States or its territories. There is no need to force an ineligible application through the wrong channel.
The international Form SS-4 routes
The application for an EIN is Form SS-4. An applicant outside the online assistant's rules files directly with the IRS using an eligible fax, mail, or—in the limited international case described below—telephone route. The form identifies the entity, its mailing and physical addresses, the responsible party, and the reason for applying. A foreign mailing address is permitted. If the responsible party has no SSN or ITIN and is ineligible to obtain one, the current instructions allow "Foreign" or "N/A" on line 7b.
For the telephone route, the applicant must have no legal residence, principal place of business, or principal office or agency in the United States or its territories. An authorized caller should have a completed Form SS-4 in front of them and be ready to answer the form's questions. The current IRS instructions list 267-941-1099, Monday through Friday from 6:00 a.m. to 11:00 p.m. Eastern time; it is not a toll-free number. The caller must be authorized to receive the EIN and answer questions about the application. Confirm the current eligibility rule, number, and hours in the IRS instructions before calling.
For fax or mail, accuracy matters because there is no interactive form to catch obvious errors. An SS-4 that contradicts itself, names the wrong responsible party, or leaves a required box blank can return as a rejection or request for more information after it has entered the processing queue.
Phone, fax, or mail: how the channels differ
Once the SS-4 is complete, the delivery method affects the timeline. The current IRS Form SS-4 instructions say a fax application can generally receive an EIN within four business days when a return fax number is provided. For mail, the IRS says to apply four to five weeks before the number is needed and describes receipt by mail at approximately four weeks. These are agency estimates, not promises; incomplete applications and IRS workload can extend them.
The honest takeaway is to choose the channel for which the applicant is actually eligible and submit a consistent application the first time. The IRS controls assignment and processing; a formation provider's “expedited EIN” fee does not change the agency's rules or guarantee a date.
What the IRS actually requires
The requirements are narrower than the anxiety around them suggests. You need an eligible entity or tax reason for the number, a responsible party the IRS can identify, and accurate mailing and physical-address information; the addresses may be foreign when that is the truth. A foreign responsible party who is ineligible for an SSN or ITIN does not need to invent a US personal tax number. Follow the current SS-4 instructions for the applicant's facts and filing channel.
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 an incomplete mailing address can turn an agency processing estimate into a lost response.
- 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. If Form 5472 is required based on the entity, foreign ownership, and reportable transactions, the filing uses the company's EIN, so an EIN problem can become a compliance problem. The exact name and details attached to the EIN also need to align with bank and marketplace records. This is why founders who cut corners at the EIN stage can hit a wall later at Amazon seller verification. An EIN issued to the wrong responsible party, or under a slightly different entity name, is a problem you carry forward.
