How do postcodes work? I live in London, N22 and the surrounding places are N13, N10, N17 and N11 � I don't understand this, wouldn't you assume that all the numbers would be close? N1 is Angel/Islington and N2 is East Finchley � not exactly next door to each other�
Can anyone tell me how postcodes work and is it like this across the Country?
Although it is not always apparent but in London they are roughly in alphabetical order. I don't know when they were originally assigned but they correspond to older postal districts, some of the names of which have lost their importance.
Just thought: in SW's case they go back to the beginning afte SW10 - hence SW11 Battersea, SW!2 Balham etc. I don't think they do this in all postal districts.
