British Army Service Numbers: Explained

See when a service number was issued by the British Army since 1950.

A Brief History Of British Army Service Numbers

Service personnel for the British Army have been issued a seven or eight digit service number since 1950.

Before the 50’s, service numbers were issued at regimental level.

These service numbers would then stay with that soldier forever.

For example, if you or I were to join the Royal Tank Regiment before 1950, our service numbers would be somewhere between 7868001 – 7891868.

If we transferred to Royal Army Medical Corps later on, the number would stay the same but be different to those who started in the RAMC.

Army Service Numbers After WW2

Due to a huge influx in new soldiers, the British Army devised a new service numbering system.

Rather than being dependant on the starting regiment, service numbers would now be issued Army wide.

The table below shows you service numbers from 1950 onwards.

25139704 to 252xxxxxAugust 2001to March 2007

April 2007 saw the new numbering structure for all tri-services start with 3000.

This system should allow for ~10 million soldiers to have a service number beginning with 3.

At the current rate of new service personnel joining, it looks as though this system will be in place for a very long time.
