AIUI, ZIP codes aren't as granular as UK postcodes. A postcode and house number/name is generally all you need to locate a UK address; the rest just makes it easier for the postman. In the US, a ZIP can cover quite a large area so it's less useful
They're similar to the ZIP+4 codes; usual US ZIP codes are approximately like postal districts (e.g., I'm currently in M13, i.e., the thirteenth postal district of Manchester).
