I sent off a package a few months ago, and now I need proof.?

Question

Does the post office keep records of these things>>>

Answer 1

Yeah if you put delivery confirmation on it or return receipt requested.  If you just slapped the regular postage on it, I  regret to say you are out of luck.  The U.S. Postal Service handles 212 billion pieces of mail annually.

Answer 2

if u sent it by regular mail. no

if you paid extra for the confirmation then yes.  you should also have a receipt.
