A five-digit road key ("Straßenschlüssel") is used in conjunction with a twelve-digit region key ("Regionalschlüssel", "Gemeindeschlüssel") to form a unique reference key for each road in Germany.

In OpenStreetMap, this allows to validate the completeness and correctness of streets. Further, it allows data consumers to identify streets without considering further administrative data.

For details of the key and its components, please refer to the German page.
