London has post codes, not zip codes.

There are thousands of post codes in London.

Every street in London has its own post code.

This is like asking for the zip code of New York.

This diagram shows all the London post codes, there are a lot :P

Best of luck :)

For the umpteenth time in this section, there isn't one. There are thousands, and they are not called zip codes.

What a moron
