# Lists of abbreviations used on British Empire World War I medals

When a World War I medal was issued to a member of Commonwealth forces, it was issued with a Service Number, Rank, Name and Regiment. This information should be on every medal that was issued during the First World War.

During World War I, there were four main medals issued: the 1914 Star, 1914-15 Star, Victory Medal, and the British War Medal.

From a service number it is sometimes possible to determine in which part of the army a medal holder served. However, this is not always the case.
