Stockport, Warrington, Wigan, Oldham, Blackburn, Blackpool, Lancaster, Carlisle and Crewe have no page of their own; their districts are in the lists further down, under the postcode area each one belongs to.

Which postcode areas and counties are covered?

The coverage spans 15 postcode areas, each listed below with its name, the counties its districts sit in and its number of covered districts.

Each area keeps the name Royal Mail gives it, except SY: its official name, Shrewsbury, lies outside the coverage, so the area is named after Malpas, its only covered town. CH carries the name Chester although Wirral is its largest covered post town.

Which postcode districts are covered in each area?

Every covered district is listed below by postcode area and post town, from M1 in Manchester to SY14 in Malpas.

Non-geographic districts, the 33 with no residents in the 2011 Census, are left off the list.
