The Pension Insurance Number

The pension insurance number

The pension insurance number is used to identify German citizens who are registered in the statutory pension insurance. It is noted, among other things, on the social security card. The number is assigned automatically by the sponsors of the German pension insurance, as soon as such an account is opened. The pension insurance number must not be identical to the health insurance number and the identifier of other companies in order to avoid “the glassy citizen”. Since the coding of the health insurance number since 2005 is based on an encrypted pension insurance number, every German newborn already receives a pension insurance number. However, the social security card will not be issued until the first job has been taken.

Structure of the pension insurance number


The total of 12-digit pension insurance number consists of a fixed number and letter combination. The first two digits indicate the area in which the pension insurer is registered for the first time. The coding does not follow the postal codes. The following two six positions represent the birthday in ddmmyy format. The ninth digit is the initial letter of the surname of the person reported. Umlauts are broken down and foreign language characters are Germanized. This is followed by a gender-specific serial number. 00-49 means male and 50-99 female. The pension insurance number ends with a single-digit check digit.

Change of pension insurance number

The pension insurance number accompanies a citizen from birth to death. Under certain circumstances, however, a change can be made. If an incorrect date or letter is used in the award, the carrier has the right to make an adjustment. If two persons are accidentally assigned the same number, both identifications become invalid and two new pension insurance numbers are issued. If a person has several insurance numbers, all but one are shut down. Finally, transsexuals have the right to change their civil status number (masculine / feminine).
