What Is an EIN and Why Is It Important?

An Employer Identification Number (EIN), sometimes called a Federal Tax ID, is a unique nine-digit number assigned by the IRS to identify your business for tax purposes.

In San Francisco, an EIN is often necessary for city permits, opening business bank accounts, and complying with local regulations.
