What is an EIN?

An Employer Identification Number (EIN), also known as a Federal Tax Identification Number, is a unique nine-digit number assigned by the IRS to business entities operating in the United States. It's used to identify your business for tax purposes, similar to how a Social Security number identifies an individual.

How to Apply for an EIN
