RM 01103.015 Composition of the Employer Identification Number (EIN)

A. Description of the EIN

The EIN is a nine-digit number in the format xx-xxxxxxx. It consists of:

  • Two initial digits that denote the Internal Revenue District in which the EIN was issued (see RM 01103.015B.) followed by a hyphen; and

  • Seven digits (the serial portion) identifying the employer or reporting entity.

    EXCEPTION: Some EIN's consist of eleven digits. In these instances the initial two digits denote the Internal Revenue District that services the area in which the employer is located.

  • Where applicable, a suffix code letter follows the number:


    for agricultural employer


    for household employer


    for Federal government employer


    for State or local government employer


    for non-profit employer


    for foreign subsidiary of a U.S. employer


    for reporting entity not subject to Social Security taxes

NOTE: State and local entities with Social Security coverage under Section 218 of the Act are assigned an EIN beginning with “69” for wage reporting purposes. This EIN is assigned by SSA and is used in addition to the Federal Employer Indentification Number assigned to the entity by IRS for income tax withholding purposes and to identify which State and local entities are covered and therefore liable for paying Social Security taxes.

B. List of Internal Revenue District Codes

The general location of the employer or reporting entity or the servicing IRS District Office can be identified from the EIN itself. This information can assist in resolving reporting problems or in developing specific wage investigations arising in claims or pre-claims actions. The following is a list of Internal Revenue Districts and their codes with parallel SSA district offices and their codes:
