gas mask canister number help.

[WannaBeAkraut]

I am a german re-enactor,and I do take my hobby VERY serious. So here's my question: I want to paint my ID number on the side of my gas mask canister,re-enactors generally use some part of there social security number ( easy to remember ). Now,I portray the 10'th SS Frundsberg. Which of the following would be a more accurate number to use : a 4 digit number in the 5000 range,or a 3 digit number in the 400 range ? Can someone PLEASE help? Danke,Andreas.
