If you're a non-US founder trying to open a US business, one question comes up almost immediately: how do you get a US EIN if you don't have a Social Security Number? The IRS's online EIN application, the fast, free, same-day option most guides point you to, requires an SSN or ITIN just to start. If you don't have either, you hit a wall in the first five minutes.
The good news is that not having an SSN doesn't block you from getting an EIN. It just means you can't use the online form, and the process takes longer. Here's exactly how it works.

Why You Need an EIN Even Without a US Business Presence
An EIN (Employer Identification Number) is essentially a Social Security Number for your business. You need it to:
- Open a US business bank account
- File US taxes for your LLC or C-Corp
- Get approved by most US payment processors (Stripe, PayPal Business, etc.)
- Sign contracts with US clients who require a US tax ID
- Hire employees or contractors in the US
If you've formed a US LLC as a non-resident, an EIN isn't optional. Almost nothing else on the list above works without it.
Can You Actually Get an EIN Without an SSN? (Yes)
Yes. The IRS allows non-US residents without an SSN or ITIN to apply for an EIN. The catch is that you can't use the instant online application, that option is restricted to applicants with an SSN or ITIN acting as the "responsible party." Everyone else has to apply manually using Form SS-4, submitted by fax or mail.
This is a genuinely different process from the one most "how to get an EIN" guides describe, because most of them are written for US residents with an SSN already in hand.
The Manual Route: Filing Form SS-4 Without an SSN
Form SS-4 is the IRS's official EIN application form. For a US applicant with an SSN, it's usually filed automatically behind the scenes through the online tool. For a non-US applicant, you fill it out yourself, leave the SSN/ITIN field blank or marked as "Foreign," and submit it directly.
You'll need:
- Your business's legal name (matching your Articles of Organization/Incorporation exactly)
- Your name and title as the "responsible party" (this can be a non-US person)
- Your foreign address
- Your business's US formation state and formation date
- A brief description of your business activity
Step-by-Step: How to Complete Form SS-4 as a Non-US Resident
- Download Form SS-4 directly from IRS.gov, not a third-party site.
- Complete Line 7b (SSN/ITIN field) by writing "Foreign" instead of leaving it blank, this is a common point of confusion, and an unmarked blank field is more likely to get flagged.
- Fill in your foreign address in the mailing address section, since you don't have a US address to provide (unless you're using a registered agent's address, which many non-US founders do).
- Choose your fax or mail option. Fax is significantly faster, current IRS processing for faxed SS-4 forms from international applicants typically runs a few weeks, while mailed applications can take 8-12 weeks or longer.
- Fax to the IRS's international EIN unit (the number is listed in the Form SS-4 instructions and changes occasionally, so always check the current version on IRS.gov before sending).
- Wait for your EIN confirmation letter (CP 575), which the IRS will fax or mail back once processed.

How Long It Actually Takes
This is the part most guides gloss over. Realistic timelines for the manual SS-4 route:
- By fax: Typically 1-2 weeks for a response, sometimes longer during high-volume periods
- By mail: Commonly 8-12 weeks, sometimes stretching further
- Compare to the online tool: Instant, for applicants with an SSN or ITIN
If you're planning to open a US bank account or sign a client contract on a deadline, this timeline needs to be built into your planning from day one, not discovered halfway through.
Common Mistakes That Get Applications Rejected or Delayed
- Leaving the SSN/ITIN field completely blank instead of writing "Foreign." The IRS sometimes rejects blank fields as incomplete rather than reading them as "not applicable."
- Formation details not matching your Articles of Organization exactly. Even small discrepancies (a missing "LLC," a different address format) can trigger a request for correction, adding weeks to the timeline.
- Using a CPN or SPN in place of an SSN. These are not valid IRS tax identifiers, using one will get an application rejected, and can create bigger problems.
- Faxing to an outdated number. The IRS's international unit fax number has changed before. Always confirm the current number on IRS.gov rather than reusing one from an old guide or forum post.
- Applying before formation is fully approved. Your EIN application needs your approved formation details. Applying too early with unconfirmed details is a common cause of rejection.
The Faster Alternative: Formation Services Built for This
The manual SS-4 process works, but it's slow, and mistakes are easy to make on a form most people only ever fill out once. If speed matters, or you'd rather not navigate IRS fax procedures from another country yourself, this is exactly the kind of problem specialist formation services exist to solve.
doola is built specifically for non-US founders in this situation, EIN application without an SSN is a core part of their formation service, not an afterthought bolted onto a product designed for US residents. They handle the SS-4 preparation and submission on your behalf, alongside LLC formation, registered agent service, and US bank account setup, which matters because these pieces usually need to happen in the right order.

What an EIN Unlocks Once You Have It
Once your EIN confirmation letter arrives, you can:
- Open a US business bank account (most banks require the physical CP 575 letter, so keep it somewhere safe)
- Apply for a Stripe or PayPal Business account
- File your annual US tax obligations (Form 5472 and 1120 for foreign-owned single-member LLCs, in most cases)
- Sign contracts with US clients who require a valid US tax ID
- Register for state-level tax accounts where applicable

FAQ
Can I get a US EIN with no US address at all? Yes. You can use your foreign address on Form SS-4, or a registered agent's US address if you already have one set up as part of your LLC formation.
Do I need an ITIN before I can get an EIN? No. An EIN and an ITIN are separate, and you don't need one to get the other. Many non-US founders get an EIN for their business first and apply for a personal ITIN later, if they need one for personal tax filing.
Can I use someone else's SSN or a CPN instead? No. A CPN (Credit Privacy Number) is not a valid IRS tax identifier, and using one on an EIN application is not a legitimate workaround. It gets applications rejected and can create bigger compliance problems.
How much faster is using a formation service compared to filing SS-4 myself? It varies, but specialist services generally cut meaningful time off the process since they know the current fax numbers, formatting requirements, and common rejection triggers that individual applicants often discover the hard way.
Does my EIN expire? No. Once issued, an EIN doesn't expire and doesn't need to be renewed, even if your business is inactive for a period.
