SOCIAL SECURITY NUMBER ALLOCATIONS

Since 1973, social security numbers have been issued by the central office of Social Security Administration, Department of Health and Human Services.

The first three (3) digits of a person's social security number are determined by the ZIP Code of the mailing address shown on the application for a social security number. Prior to 1973, social security numbers were assigned by SSA field offices. The number merely established that his/her card was issued by one of the SSA offices in that State.

THIS DATA IS STRICTLY FOR INFORMATIONAL PURPOSES

NOTE: The same area, when shown more than once, means that certain numbers have been transferred from one State to
another, or that an area has been divided for use among certain geographic locations.

Any number beginning with 000 will NEVER be a valid SSN.
