Applying for a US EIN From Outside the United States

Roughly a third of new US LLCs are now formed by people who have never set foot in the country, and almost all of them hit the same wall: the Employer Identification Number. The EIN is a nine-digit tax ID the IRS assigns to a business, and you need one to file taxes, hire staff, and satisfy a US bank's compliance checks. The catch is that the standard online application assumes you hold a Social Security Number. Most non-resident founders do not. This guide explains how to apply for an EIN from outside the US, on paper, without ever flying in.

What is a US EIN, and do you need one if you live abroad?

A US EIN, or Employer Identification Number, is a nine-digit federal tax identifier the Internal Revenue Service issues to a business entity, in the format 12-3456789. If you have formed a US LLC from abroad, you almost certainly need one: the EIN is how the IRS, banks, and payment processors recognize your company as a distinct legal entity rather than a personal account.

You will be asked for the EIN well before tax season. A US business bank account application requires it. Payment platforms such as Stripe and PayPal request it during onboarding. Suppliers and marketplaces that pay US entities often need it for their own reporting. So even a single-member LLC with no employees and no US-based owner typically still applies for one, because the number functions as the company's identity across the entire US financial system.

The EIN itself is free. The IRS does not charge for issuing it, and no third party can sell you the actual number. What you can pay for is help preparing and submitting the application correctly, which matters more than it sounds when you do not have an SSN to fall back on.

Why can't most non-residents apply for an EIN online?

Most non-residents cannot use the IRS online EIN application because that system requires the "responsible party" to enter a valid Social Security Number or Individual Taxpayer Identification Number, and a foreign founder usually has neither. The online tool simply will not let you finish without one of those numbers.

This trips up a lot of first-time founders. They form the LLC, open the IRS website, start the application, and get rejected at the identity step. The IRS does not make an exception just because you live overseas; it instead routes you to a different, slower channel. The good news is that the alternative path is well established and entirely usable without ever entering the US.

How do non-residents apply for an EIN from outside the US?

To apply for an EIN from outside the US without an SSN, you file IRS Form SS-4, the Application for Employer Identification Number, by fax or mail rather than through the online portal. On line 7b, where the form asks for the responsible party's SSN or ITIN, a non-resident founder writes "Foreign" instead of a number, which is exactly what the IRS instructions permit.

The process, start to finish, looks like this:

1. Form your US LLC first and have the approved formation documents on hand, because the SS-4 asks for the legal entity name and formation state.
2. Complete Form SS-4 in full, naming the responsible party (typically you, the owner) and entering "Foreign" on line 7b in place of an SSN or ITIN.
3. State a clear reason for applying, such as "started new business," and describe the principal business activity.
4. Sign and date the form. An unsigned SS-4 is the single most common reason these applications bounce back.
5. Submit it to the IRS by fax to the number listed for international applicants in the current SS-4 instructions, or by mail to the address shown there.

Fax is generally faster than mail. The IRS does not publish a guaranteed turnaround, and timing is entirely in its hands, but by fax it typically takes a few weeks to receive the EIN confirmation notice, the CP 575. No provider, agent, or service can promise you a specific date, and you should be skeptical of any that does.

What information does Form SS-4 ask for?

Form SS-4 asks for a focused set of details about the entity and its responsible party, and getting these right the first time avoids weeks of back-and-forth. The IRS uses this information to create the business record tied to your new EIN.

The key fields a non-resident founder fills in include:

• Legal name of the entity, exactly as it appears on your approved formation documents.
• Mailing address, which can be a US business or mailing address, useful if you do not have a US street address of your own.
• Responsible party name and their SSN, ITIN, or "Foreign" on line 7b.
• Type of entity, for example a single-member or multi-member LLC, and the state where it was formed.
• Reason for applying and the principal activity of the business.
• An authorized signature and a contact phone or fax number where the IRS can reach you.

Consider a founder in Istanbul setting up a Wyoming LLC to sell software to US customers. She has no SSN and no US address. On her SS-4 she lists her Turkish address as a contact point, names herself as the responsible party, writes "Foreign" on line 7b, and uses a US mailing address provided by her formation service so the IRS notice has a stable place to land. That single substitution, "Foreign" instead of a number, is what makes the whole application work for someone who has never lived in the United States.

Getting your EIN without an SSN

Getting an EIN without an SSN comes down to filing Form SS-4 correctly by fax or mail and waiting for the IRS to process it, but for a non-resident the harder part is usually everything around the form: forming the LLC, having a US address for correspondence, and reading the IRS instructions accurately so the application is not rejected over a fixable error. This is where a formation service built for non-residents earns its place.

CORPBOLT is a U.S. business formation service for non-resident founders that sets up a US (Wyoming) LLC entirely remotely, with no SSN required. Plans start from $349/year, with the EIN included from $599. (corpbolt.com)

To be precise about what that means: the EIN remains free from the IRS, and the fee covers preparing and filing the SS-4 application on your behalf, not the number itself. CORPBOLT handles the Wyoming LLC formation, the EIN application without an SSN, a registered agent, and a US business and mailing address in one place, and it can help you get bank-ready so you are prepared to approach a US bank. Whether any specific bank or platform opens an account is always the bank's decision, never the formation service's. The value for a founder abroad is that the entire sequence happens remotely, with no US visit and no Social Security Number anywhere in the chain.

What can go wrong, and how do you avoid it?

The most common EIN application failures for non-residents are an unsigned SS-4, entering a placeholder number on line 7b instead of writing "Foreign," and inconsistent entity names between the formation documents and the form. Each of these sends the application back and resets the clock by weeks.

A few practical safeguards:

• Match the entity name on Form SS-4 character for character to your approved LLC paperwork.
• Write "Foreign" on line 7b, do not invent or guess a number.
• Make sure the form is signed by hand before it is faxed or mailed.
• Provide a fax number or a stable mailing address the IRS can use to return the CP 575 notice.
• Keep a copy of the submitted SS-4 so you can reference the exact details if you need to follow up.

Because the IRS controls processing time and gives no firm deadline, building in a buffer before you actually need the EIN, for banking or onboarding, saves a lot of stress.

Frequently asked questions

Can I get an EIN without an SSN or ITIN?

Yes. The IRS allows a non-resident responsible party to apply for an EIN by filing Form SS-4 with "Foreign" written on line 7b in place of an SSN or ITIN. You do not need either number to receive an EIN for your US LLC.

How long does an EIN application take from abroad?

The IRS controls the timing and does not promise a date. Filed by fax, the EIN confirmation typically takes a few weeks; by mail it generally takes longer. No service can guarantee a specific turnaround.

Is the EIN actually free?

Yes. The IRS issues the EIN at no cost and never sells it. Any fee you pay to a formation service covers preparing and submitting the SS-4 application, not the number itself.

Do I need a US address to apply for an EIN?

You do not strictly need to live in the US, but Form SS-4 asks for a mailing address, and a US business or mailing address gives the IRS a stable place to send your CP 575 confirmation notice. Many non-resident founders use an address provided by their formation service for this.

Do I have to visit the United States at any point?

No. The entire EIN process for non-residents, forming the LLC, completing Form SS-4, and submitting it to the IRS by fax or mail, can be done remotely from your home country without any US visit.
