What Is an EIN and How Long Does It Take to Get One?

Aug 19, 2026

Quick answer: An EIN (Employer Identification Number) is a 9-digit tax ID issued by the US Internal Revenue Service (IRS) to a business, similar to a Social Security Number (SSN) but for an entity. If the owner has an SSN, an EIN can be issued instantly by applying online through the IRS website. If the owner is a foreign national without an SSN, the application must be submitted by fax or mail, and processing usually takes 4–8 weeks.

What Is an EIN Used For?

  • Opening a US business bank account
  • Filing federal and state taxes
  • Registering seller accounts on Amazon, Shopify, Stripe, PayPal Business
  • Signing contracts with US partners and suppliers

How to Apply for an EIN Without an SSN

Foreign nationals without an SSN/ITIN need to fill out Form SS-4 and submit it by fax or mail to the IRS (online filing isn’t available). This step is prone to delays or rejection if information is filled in incorrectly, especially the “Responsible Party” field. AWE Global helps prepare and file EIN applications correctly to shorten the wait.

Does an EIN Expire?

No. Once issued, an EIN is valid permanently and doesn’t need renewal, even if the business temporarily stops operating (unless it’s formally dissolved).
