I have the same set-up. The postman may leave a post office pick up card. Depends on how he feels. UPS Fedex will bring big stuff to the house. You will get a number address from the post office if you dont already have one. 911 address i think is law now, has todo with how many yards/feet you are off the main road so fireman can find your house. My house number is on the mail box and also on the drive to the house.
