The postcode area originated in 1857 as the N district of London. In 1917 it was subdivided into 22 numbered districts.[3] The Northern head district was designated as N1 and the rest of the numbering followed the alphabetical order of the other districts' main names. Most districts include local areas known by their own specific names (see table below). The official post town for all N postcodes is LONDON; district names do not form an essential part of postal addresses.[2] N81 is a non-geographic postcode district.[4]
