Better UK post codes

Current post codes take the form of 8 alphanumeric characters, but that only indicates a street (or one side of the street typically).

What we really need is a post code which includes the property reference.

So CB1 2QP which is Abbey Street in Cambridge gets an additional number at the end to indicate the property number, making it CB1 2QP 14.

Each post code may have up to 999 properties on it, and so the number can be anything from 1-999 (does not need to be zero padded). The 14 does not necessarily need to correlate with the building number, but if the street is numbered, those numbers should correlate. If the buildings have names they should be assigned a number.

So when we phone up to give our address and order something, we only need to provide CB1 2QP 14, and not need the person at the other end to select our house name from a big drop-down list.
