Help please with query on 1939 Register

[Malshie]

Good afternoon,
On the 1939 Register my great uncle has next to his name the initial
PWC/525/14437.

Anyone know what it refers to please?
Thank you
Malshie

Good morning, thank you Stan for your reply. Kind of makes sense. On the register all of the other people recorded were around the same age as my gr uncle. But he was the only person who had these initials by his name.
