An Employer Identification Number (EIN) is a nine digit number associated with a company or corporation. The Internal Revenue Service (IRS) issues an EIN to a business entity. Most businesses are required to have an EIN. A sole proprietorship can use either an EIN or the owner's social security number to identify the business.

It is relatively easy to verify that the EIN you have for your company is valid.

Instructions

  1. 1

    Check the list below to see if you have a valid EIN prefix. An EIN prefix is the first two digits of the EIN. If the IRS issued the number before 2001, the EIN prefix specifies the geographic area in which the business resides. Starting in 2001, the IRS changed the EIN prefix to correspond to one of ten different campuses. Additionally, there is also a prefix, which corresponds to the Small Business Administration and to applications submitted on the IRS website.

    According to the IRS, the valid campus or location EIN prefixes are:

    Andover--10, 12 Atlanta--60, 67 Austin--50, 53 Brookhaven--01, 02, 03, 04, 05, 06, 11, 13, 14, 16, 21, 22, 23, 25, 34, 51, 52, 54, 55, 56, 57, 58, 59, 65 Cincinnati--30, 32, 35, 36, 37, 38, 61 Fresno--15, 24 Kansas City--40, 44 Memphis--94, 95 Ogden--80, 90 Philadelphia--33, 39, 41, 42, 43, 45, 46, 47, 48, 62, 63, 64, 66, 68, 71, 72, 73, 74, 75, 76, 77, 81, 82, 83, 84, 85, 86, 87, 88, 91, 92, 93, 98, 99

    Internet--20, 26, 27 Note: The Philadelphia campus previously assigned prefixes 26 and 27. Small Business Administration--31
