Answer 2

Postcodes were introduced between 1959 and 1974. Before then, mail was addressed using a postal town and county name. The latter ensured addresses were fairly unambiguous, although there are still some instances of multiple towns in a county having the same name. Postcode areas are determined by distance from sorting offices and do not follow county boundaries at all - in fact, they also cross the boundaries between England, Wales and Scotland.

Answer 3

If you are referring to the UK "Postcode", this was started by the Royal Mail in 1959 and so just celebrated it's 50th "birthday" in the UK. However, the use of postcode systems is not uniform across the world and as such, each country usually has its own variant.

Answer 4

Partial Post Codes were first introduced in 1959 but the system wasn't fully operational until 1974.
