Post Codes

There is something to be said for our postal service. Sometimes knocked, we run ecommerce sites and use the Royal Mail daily. They are fantastic. But have you ever wondered about post codes?

In the USA they use zip codes. A 5 digit number of which there are around 42,000 of them. In Canada, strangely, they have 800,000! Here in little old UK we just use 1,700,000 of them. Wait a minute, did you say one million, seven hundred thousand of them? I'm starting to go grey. No wonder they know where to put the letters.

So, why do I need post codes? You can find people and places using parts of the address but to get driving directions from google you need a post code. If I needed post codes then I needed a database to put them in...
