british army service numbers
Soldiers in the British Army are given an eight-digit number, e.g. 25232301. Prior to 1920 each regiment issued their own service numbers which were unique only within that regiment, so the same number could be issued many times in different regiments.ntil 2007 and the introduction of the Joint Personnel Administration (JPA) system, Army Officers were issued with a six-digit service number. Newly commissioned officers now receive an 8-digit service number, but 6-digit Officers' numbers issued prior to the introduction of JPA remained unchanged.
