Get an EIN Without an SSN: A Complete Guide for International Founders

An Employer Identification Number (EIN) is one of the first records many foreign founders need when starting a U.S. business. If you do not have a Social Security Number (SSN), you can still obtain an EIN by using the IRS process designed for applicants without an SSN.

This guide explains why an EIN matters, when international founders need one, how the application works without an SSN, and what to avoid along the way.

What an EIN is and why it matters

An EIN is a federal tax identification number issued by the IRS. It is used to identify a business for tax and reporting purposes, much like an SSN identifies an individual.

For many U.S. business activities, an EIN is more than just a tax number. It may be required to:

• Open a business bank account
• Hire employees
• File business tax returns
• Register for sales tax accounts in some states
• Work with payment processors and marketplace platforms
• Separate business and personal financial records

For foreign founders, an EIN also helps establish a U.S. business identity even when the owner does not live in the United States.

Can you get an EIN without an SSN?

Yes. The IRS allows non-U.S. residents and other applicants without an SSN to request an EIN.

The key difference is that you cannot use the online EIN application if you do not have a qualifying U.S. taxpayer identification number. Instead, you usually apply by submitting IRS Form SS-4 through fax or mail, or by calling the IRS if you are an authorized third party.

That means the lack of an SSN does not block your business formation plans. It only changes the application method.

When international founders usually need an EIN

An EIN is commonly needed in situations such as:

• Forming an LLC or corporation in the United States
• Opening a U.S. business bank account
• Hiring U.S. employees
• Filing federal tax forms
• Registering for state tax accounts where required
• Selling on platforms that request business tax information
• Importing goods into the United States
• Building a formal business profile for vendors and partners

Even if your company has no U.S. office, an EIN may still be necessary if your business activity touches the U.S. market.

How to get an EIN without an SSN

The process is straightforward, but the details matter.

1. Form your business first

In most cases, you should establish the entity before applying for the EIN. For example, if you are forming an LLC, make sure the state filing is complete and approved.

You will need the exact legal name of the entity, the entity type, and the responsible party details before filling out the IRS form.

2. Complete IRS Form SS-4

Form SS-4 is the application for an EIN. It asks for basic information about the business, including:

• Legal entity name
• Trade name, if any
• Mailing address
• Entity type
• Reason for applying
• Responsible party information
• Principal business activity

If you do not have an SSN, you should leave the SSN field blank unless the form instructions indicate an acceptable alternative. The IRS provides specific guidance for applicants without a taxpayer identification number.

Accuracy matters here. Small errors can delay processing or cause the IRS to reject the application.

3. Choose the correct submission method

If you do not have an SSN, the usual methods are:

• Faxing Form SS-4 to the IRS
• Mailing Form SS-4 to the IRS
• Calling the IRS if you are a third-party designee authorized to apply on behalf of the business

Fax is often faster than mail. Mail can take longer, especially if the IRS requests clarification or correction.

4. Wait for the EIN confirmation

Once the IRS processes the application, it issues the EIN assignment notice. Keep this notice in a secure place. You will use it for banking, tax filings, and other business records.

Common mistakes to avoid

Many EIN delays happen because of avoidable filing issues. Watch for these problems:

• Using the wrong legal name for the entity
• Mixing up the responsible party and the entity name
• Leaving required fields incomplete
• Choosing an incorrect entity type
• Entering an address that does not match official records
• Applying before the business is properly formed

If you are a foreign founder, another common mistake is assuming the online application is available without an SSN. In most cases, it is not.

Why the EIN matters for a U.S. startup

For a founder outside the United States, the EIN is often a practical bridge between entity formation and operating the business.

It can help you:

• Set up banking and accounting workflows
• Separate business operations from personal finances
• Prepare for tax registration and compliance
• Onboard platforms, vendors, and service providers
• Present a more credible and organized business profile

When handled correctly, the EIN process supports the next steps in your U.S. business setup rather than slowing them down.
