The M50 district of Salford was formed out of west of M5 in 2002.
Before the introduction of postcodes in the 1960s, Manchester along with other major cities like Birmingham, Liverpool and Sheffield was divided into numbered postcode districts. With a few exceptions these numbers made up the outcode (the first part of the postcode). The districts were based on Manchester and Salford together and districts outside the city boundaries were also included.
For example, the City Centre had postcode districts 1 - 4 (north-east, south, west and north-west respectively: Manchester 1 was around Piccadilly and 4 was around Victoria). 5, 6, 7 and 8 were in Salford and then the sequence continued across north Manchester and so round to M17 (Trafford Park). M18 onwards were further out still.
