How To Find A WW2 Service Number

This article will help you to easily identify a WW2 service number and how to see what regiment or corps they served in.

A Quick Guide To Understanding Service Numbers

Every soldier is issued with a service number.

A service number helps to identify an individual person and can be the link between them and their qualifications, previous postings, medical records and much more.

If your relative served in the military during WW2 and you’re not sure how to find a WW2 service number, it might be quite a task to find their service number.

Fortunately, you can search the National Archives if you know their surname and when they served.

If that doesn’t work, check certificates, documentation and their Army Book 64 if you have it.
