Wow I am not ALLONE! For years I have been placing my home address over my PO Box (I have had the same box # since I was 17 and now I am 61!!!) and sometimes some places can never figure it out. My post office has it's very own zip code, just for boxes. Well today, in my mail was a memo from USPO saying that they will have a new agreement to sign so that they can ACCEPT UPS/DHL/FEDEX/ETC packages addressed to the PO street address and box #!!!!!! Don't know how much extra, but they say they will even email when a package is received!!!!! Guess they need extra $$$! How many years I have had to work with my physical address and my mailing address and how many people I have confused. The state can't get my zip code right - they keep using my physical address zip, not my PO Box. I finally found a credit card company that maintains both of my addresses for verification on orders - so I use only this card for internet purchases. Good luck to everyone!!!!!!
