How Non-US Residents Can Quickly Apply for an EIN: Step-by-Step Guide, Common Mistakes, and Pitfalls to Avoid

Non-US residents or companies often cannot apply for an EIN online via the IRS website. This guide explains the full application process, common mistakes, hidden compliance risks, and compares service providers so you can obtain your EIN and CP-575 securely and quickly.

🏁 Introduction

For many non-US residents or companies without a physical business presence in the United States, obtaining an EIN (Employer Identification Number) is the first step to doing business in America. However, the IRS application rules are complex, especially due to online application restrictions, strict field requirements, and Responsible Party compliance issues, which frequently lead to delays or outright rejections.

SpeedEIN specializes in assisting non-US applicants with EIN services, helping clients obtain an EIN within 10 business days and receive the CP-575 confirmation letter within 20 business days, while avoiding common pitfalls and mistakes.


📌 Why Can’t Non-US Residents Apply for an EIN Online?

According to IRS Publication 1635 and official guidance:

  • The IRS EIN Assistant online system is only available to applicants with a principal business location in the US.
  • If you use a non-US address or the Responsible Party is not a US person, you must apply by phone or by submitting a paper SS-4 form.
  • This means non-US residents must communicate with the IRS across time zones, and the SS-4 form contains 18 sections and 35 main fields, where any small error could result in rejection.

⚠️ Common Pitfalls and “Traps”

1. Mailing Address Issues

The IRS sends the CP-575 confirmation letter and all important tax notices to the Mailing Address provided on your application. If this address is invalid or incorrect, consequences can be severe.
Many low-cost service providers fail to mention this and may even use virtual addresses. If the IRS verifies it, your EIN could be rendered invalid.

2. Responsible Party Violations

The IRS requires the Responsible Party to be the actual individual controlling the company—not a fictitious name, corporate entity, or service provider. Some non-compliant providers use their own information, which is illegal and can cause serious tax issues later.

3. Incorrect Information

The SS-4 form demands exact spelling, capitalization, and formatting. Even a minor typo can delay your application for weeks.
