What is a Feldpostnumber?

Feldpostnummern / Feldpost Numbers — Feldpost numbers for most units consisted of a 5-digit number.  Prefixes were sometimes used to denote service (L for the Luftwaffe, M for the Kriegsmarine, SCH for coastal defense units, etc.), but as these were not always used, they are not included in the the database.

Sammelfeldpostnummern / Collective Feldpost Numbers — These numbers were used in locations with a high concentration of troops, primarily in large cities. They typically consisted of a 5-digit number, followed by a 1- or 2-digit letter (A, B, C, AB, etc.).  These are not yet listed in the database.

Date Ranges — The original feldpost number directories published during WWII did not list with specificity the start and end date of use for each number.  Rather, they were published on an irregular basis, and listed those number in use at the time of publication.  For this reason, subsequent compilations of this data (including this database) have had to rely on date ranges to indicate periods of use.  Any specific dates known are included within the text of the unit description.
