Because the post office box exists today doesn't mean that it was the address of the Squadron which would have been against regs that gave you your address -- Air Force did not pay for post office boxes.

Oh, I agree.
I am just curious if POBox 3456 ever was in the zip in question.
I personally doubt it.
An interesting problem arose that precipitated writing a special rule for PO Box rental periods ~ just about every intelligence gathering agency on Earth rented boxes all over the US.
We are the only people spies trust.
However, such activities are always "black funds", but there are budgets, and they are controlled by former field operatives (think of a KGB assassin in charge of your budget).
They all needed flexibility concerning when the rent would be due. Everybody went away happy with the solution.
