What was Beaver Cleaver's locker number at school?

I've checked on a few episodes now and I don't think his locker has a number on it.

UncleBilly is correct. We never do learn what the Beaver's locker number is during school. I believe he states his locker combination at one time, but I cannot recollect which episode and what scene that took place. :)

I don't recall Beaver ever talking about his combination ( of course my memory gets foggy sometimes!) but on "Wally's Pug Nose", Wally is talking to Gloria and tells her that his locker is #221 and his combination is 10-30-11.
