California Federal Tax ID numbers are issued by the IRS in a nine-digit format such as 12-3456789.

They uniquely identify your business to the government in the same way that Social Security Numbers do for individuals. But various non-government vendors will also request the number during routine commerce in California. For example, California banks will require you to provide one before opening a business bank account.

Generally, California businesses need a Federal Tax ID.

Establishing a new California EIN number / Federal Tax ID is often one of the first things a new California business does. One common reason is that most business license applications will ask for the ID.

Federal Tax IDs can go by many names in California, including:

Employer Identification Number (EIN)
Federal Employer ID Number (FEIN)
Federal ID Number (FIN)
Federal Tax Number (FTN)
Taxpayer Identification Number (TIN)
Federal Taxpayer Identification Number (FTIN)
Or often times, just Tax ID or Tax Number
