Depends.

Old house was on the cusp of 3 zip codes.

You had to get the town and zipcode exactly 100% correct or no go.

Sometime I'd get a notice from the post office that they had package that they could not deliver because my house number was too far down the street for that zip code.

So the f'rs knew where I was, knew what the mistake was but would still not deliver.
