This question is asked repeatedly and the answers the same, London uses the UK postal code where each street/part of a street or even single building has it's own postal code. It is one of the largest cities in the Western world (only topped By Paris, it is bigger than all US cities). To find a post code if you have the address (or even part of the address)use the Royal Mail post coide finder at http://www.royalmail.com/find-a-postcode...

This pointless question is asked too often.

There is no London postcode, just as there is no Seattle zip code. Every street in London has its own postcode.

London has Many postal codes depending on Location/Street

Firstly, this is not a question, it is just three words. Secondly, of course there is more than one. WHY do people keep asking this stupid question?

Ask properly. That is not the way to phrase your question.
