Top 7 EIN Application Mistakes Made by Foreign Companies

Applying for an EIN (Employer Identification Number) in the United States can seem straightforward — but for foreign entities, it’s filled with traps. A single mistake can result in your EIN request being ignored, rejected, or worse, tied to incorrect information that’s impossible to fix. This article lists the 7 most common EIN mistakes foreign companies make, and how SpeedEIN ensures a smooth and accurate application process.

7No Copies or Records SavedDidn’t save SS-4 form or EIN numberCan’t appeal or recover your EIN

❗ Why These Mistakes Are So Dangerous

  • The IRS doesn’t notify you about errors. If your application has issues, you won’t get an email or call — it’s simply ignored or returned by mail.
  • CP575 is only mailed once. This official EIN confirmation letter cannot be emailed or downloaded. A single address mistake means you may never receive it.
  • Once linked, EIN info can’t be changed. If you enter the wrong name or mark the wrong box, your EIN is tied to incorrect data — and that can’t be fixed later.
