What is an Employer Identification Number (EIN)?

An Employer Identification Number (EIN) is a federal identification number for your business. It is a nine-digit number that is similar to a Social Security number. However, it is formatted as 12-3456789 instead of 123-45-6789 on official forms. An EIN is also referred to as a Federal Tax Identification Number. Separate business entities like corporations and LLCs need them for tax purposes. Sole proprietors share their EINs to avoid sharing their Social Security Numbers when conducting business.
