IRS EIN Application Process For Non US Residents: Which Option Is Best for Foreign Entrepreneurs?

Which EIN Application Process For Non US Residents Is Right for Your Business?
Option 1: Online Application
Many entrepreneurs assume the IRS online EIN application is available to everyone. Unfortunately, that’s one of the biggest misconceptions.
The IRS online EIN application is primarily available to applicants who have a valid Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) and meet the IRS eligibility requirements.
As a result, many foreign entrepreneurs and non-U.S. residents without an SSN or ITIN cannot use this method. If you don’t have an one, you can apply for ITIN online for future tax purposes, but you don’t need to wait for it to receive your EIN. Since an ITIN application can take 5-6 months to process, many non-residents choose to apply for their EIN using other IRS-approved methods, such as fax, which is often processed in around 10–14 business days when the application is completed correctly.
Advantages of Online Application
- Fast when eligible
- Immediate EIN assignment in many cases
- No mailing or faxing required
If you’re applying from outside the United States, don’t assume the online system will be available for your situation.
Option 2: Applying by Fax
Many foreign business owners choose to submit Form SS-4 by fax.
This method is often preferred because it can be quicker than mailing physical documents while still allowing international applicants to submit their application remotely. If you’re applying from outside the United States, you can generally fax your completed Form SS-4 to the IRS at +1-304-707-9471. It’s also recommended to include your own fax number on the form so the IRS can send your EIN confirmation back by fax.
However, most entrepreneurs don’t own a fax machine because it’s not something they use regularly. Instead of purchasing a fax service or learning the IRS submission process for a one-time application, many non-residents choose to work with a professional service provider like US Global Startup.
Advantages of fax
- Available to eligible foreign applicants
- No international postage required
- Often processed sooner than mailed applications
Things to Remember When Doing Fax
- Ensure Form SS-4 is completed accurately.
- Use the correct IRS fax number for your circumstances.
- Keep a copy of everything you submit.
- Monitor for any IRS follow-up requests.
A clear, complete application helps reduce the likelihood of delays.
Option 3: Applying by Mail
The traditional mail method is still accepted by the IRS.
Some businesses prefer this option, especially when they are already preparing other paperwork to send.
Advantages of Mail
- Widely accepted
- Useful for applicants who prefer physical documentation
Limitations of Mail
- International delivery can take time.
- Processing is generally slower than fax.
- Corrections may take longer if additional information is requested.
If your business needs an EIN quickly, mailing may not be the most efficient option.
Option 4: Applying by Telephone
The IRS also provides a telephone application process for eligible international applicants.
Generally, this option is available to applicants whose principal business is located outside the United States or U.S. territories and who have completed Form SS-4. Applicants can contact the IRS Business & Specialty Tax Line at +1-267-941-1099 (not toll-free), available Monday through Friday, 6:00 a.m. to 11:00 p.m. Eastern Time (ET).
During the call, the applicant (or an authorized third party) must be able to verify the business information and answer the IRS representative’s questions. If everything is in order, the IRS representative may process the application and assign an EIN during the call.
Advantages of Phone
- Specifically designed for eligible international applicants
- No need to mail Form SS-4
- May result in faster processing when all requirements are met
Considerations
Before calling:
- Complete Form SS-4 in advance.
- Ensure you understand every answer on the form.
- Be prepared to answer questions about your business.
- Call during IRS operating hours.
Because the conversation is conducted in English and follows IRS procedures, some applicants choose to seek professional assistance if they’re unsure about any part of the application.
For the IRS telephone EIN application, “eligible international applicants” generally means:
- The applicant’s principal business is located outside the United States or U.S. territories.
- The applicant (or an authorized third party) is authorized to receive the EIN.
- The applicant has completed Form SS-4 and can provide all required information during the call.
- The caller can verify the business details and answer the IRS representative’s questions.
Which EIN Application Process Is Best for Non-US Residents?
There’s no single “best” option for every business.
The right choice depends on:
- Your eligibility
- Whether you have an SSN or ITIN
- How quickly you need the EIN
- Your comfort level with IRS procedures
- Whether you want to handle the process yourself or use professional assistance
For most foreign entrepreneurs who do not have an SSN or ITIN, the fax application is often the most practical option. When Form SS-4 is completed accurately and all required information is provided, the IRS may process fax applications in approximately 10–15 business days, making it one of the fastest methods available to many international applicants.
If you already have a valid SSN or ITIN and meet the IRS online application eligibility requirements, the IRS online EIN application is usually the fastest and most convenient option, as many applicants receive their EIN immediately after a successful submission.

Frequently Asked Questions
Common questions about EIN application process for non US residents.
Which IRS EIN Application Method Is Fastest for Foreign Entrepreneurs?
For eligible U.S. applicants, the IRS online application is the fastest method and usually issues an EIN immediately. However, most foreign entrepreneurs and non-U.S. residents are not eligible for the online system. For international applicants, the telephone application may allow an EIN to be issued during the call if all information is correct, while fax applications typically take around 10 - 14 days business days. Mail applications generally take 6 - 7Â weeks or longer depending on IRS processing times.

Can I Switch to Another EIN Application Method If My Application Is Still Pending?
It's generally not recommended to submit another EIN application through a different method while your original application is still being processed. Sending duplicate applications can create confusion and may delay processing. If you haven't received a response within the expected timeframe, it's better to contact the IRS to check the status of your existing application before submitting a new one.
Can Someone Else Apply for an EIN on My Behalf?
Yes. You can authorize a third-party designee, such as a tax professional, accountant, or business formation service, to apply for an EIN on your behalf. To do this, you must complete the Third-Party Designee section on IRS Form SS-4, which allows the authorized person to communicate with the IRS regarding your EIN application.
What Information Should I Check Before Submitting Form SS-4?
Before submitting Form SS-4, verify that your legal business name, state of incorporation, business entity type, responsible party details, and mailing address exactly match your company formation documents. Also ensure you've selected the correct reason for applying and answered all required fields. Even minor errors or inconsistent information can result in processing delays or requests for additional clarification from the IRS.
What Happens If I Make a Mistake on Form SS-4?
If your Form SS-4 contains incorrect or incomplete information, the IRS may contact you for clarification or request additional details before issuing your EIN. In some cases, errors can delay processing.
Do I Need to Submit My Company Formation Documents with Form SS-4?
Generally, the IRS does not require you to attach your company formation documents when submitting Form SS-4.
Can I Track the Status of My EIN Application?
The IRS does not provide an online tracking system for EIN applications. If your application has taken longer than the expected processing time, you can contact the IRS Business & Specialty Tax Line to inquire about its status.
