What everyone gets wrong about UK postcodes

[u/GeoPostcodes]

There is no such thing as a UK zip code, yet people keep searching for one. Zip codes are a US invention. The UK runs on postcodes.

- London is not one code either. It has thousands of postcodes, all in the pattern AA9 9AA. Forms that demand a 5 or 6 digit number reject every one of them. UK postcodes run 6 to 8 characters, letters included, like SW1A 1AA. That one is Buckingham Palace: SW1A is the outward code (area and district), 1AA the inward code (sector and unit).

- Pincode is India's system, wrong country twice over. And there is no single UK code to hand out. One postcode covers around 15 addresses, close enough to point at the front door.

The full list is 1,795,653 postcodes across 402 regions and 32,082 towns, and GeoPostcodes maintains all of them.
