If you’re a non-resident planning to do business in the United States, getting an Employer Identification Number (EIN) is a key step. An EIN identifies your business for tax purposes. It is also required for opening a US bank account, registering with Stripe, and filing your business tax returns.
In this 2025 guide, we’ll walk you through how non-residents can get an EIN without stress, what’s changed this year, and how to avoid the most common mistakes. This post is up to date with the latest IRS procedures and best practices for global founders, freelancers, and entrepreneurs.
What is an EIN and why do non-residents need one?
An Employer Identification Number (EIN) is a 9-digit number issued by the IRS to identify a business for tax purposes. It is similar to a Social Security Number (SSN), but for companies.
While you’ll need to form your US LLC or C Corporation first, an EIN is required soon after to handle key business activities.
Common reasons non-residents apply for an EIN:
- Opening a US business bank account
- Registering with Stripe, Amazon, or PayPal
- Filing taxes with the IRS
- Hiring US-based employees or contractors
- Complying with state and federal reporting requirements
Importantly, you do not need to be a US citizen or resident to obtain an EIN.
Can a non-resident get an EIN without a SSN?
Yes. As a non-resident, you can apply for and receive an EIN in 2025, even if you don’t have a Social Security Number (SSN) or US address. The process involves submitting IRS Form SS-4 by fax or mail (since the IRS online application is still restricted to individuals with an SSN or ITIN).
Step-by-step: How to apply for an EIN as a non-resident
1. Form your US business entity
Before you apply for an EIN, you need a legal entity, typically a Limited Liability Company (LLC) or C Corporation. This includes choosing a business name, state of formation, and registered agent.
Tip: Our firm handles the full company formation process, including EIN filing and assistance with bank account opening, in one bundled service.
2. Gather the required information
To apply for an EIN, you’ll need:
- Legal name of your entity
- Business description
- US mailing address (a registered agent or virtual address is acceptable)
- Entity type (LLC, corporation, etc.)
- Name of the “responsible party” (must be an individual, not a company)
- Reason for applying (e.g. starting a new business)
3. Complete IRS Form SS-4
Download the latest version of Form SS-4 from the IRS website. Fill it out carefully. Many people make mistakes that can delay processing. Key details for non-residents:
- Line 7a: Responsible party name
- Line 7b: Put “ForeignUS” for SSN/ITIN
- Line 9a: Check your entity type
- Line 10: Reason for applying: “Started a new business”

4. Submit the form to the IRS
As of 2025, non-residents still cannot apply online. You have to submit the form the old-fashioned way by:
- Fax: +1 855-641-6935 if you already have an LLC registered in the US. Use +1 855-215-1627 if you don’t have any registration in a US state, e.g. when you need an EIN for a foreign business
- Mail: Internal Revenue Service, Attn: EIN Operation, Cincinnati, OH 45999, USA
Fax is usually the fastest method, with approvals in 5–15 business days.
5. Receive your EIN confirmation
Once approved, the IRS will send you a confirmation letter (CP 575) by mail or fax. If you applied via fax and included a return fax number, you may get it faster.
How long does it take to get an EIN in 2025?
As of 2025, the typical processing time for an EIN application submitted by a non-resident depends on the method of submission:
- By fax: Most applicants receive their EIN within 5 to 15 business days, provided the form is filled out correctly and a return fax number is included.
- By mail: This method can take 4 to 6 weeks or longer, especially during peak IRS processing periods.
Keep in mind that any errors or missing information on Form SS-4 can result in delays. Using a professional service to file on your behalf can help ensure faster, smoother processing.
Common mistakes to avoid
Non-residents often face delays because of easily avoidable errors. Here’s what to watch out for:
- Trying to apply online without an SSN
- Not including a return fax number (if faxing)
- Using a non-US address without a registered agent
- Filling out Form SS-4 incorrectly
- Listing an entity as the “responsible party”
- Listing only one member for a multi-member LLC
- Selecting the wrong entity type
Listing all owners and selecting the correct entity type is crucial because the entity type determines your tax filing requirements. A single-member LLC must file different tax forms (Form 5472) than a multi-member LLC (Form 1065) or a C Corporation (Form 1120). Our experienced team can advise you on the best entity type and also file your tax returns.
