KML is from Wikidata The L postcode area, also known as the Liverpool postcode area, is a group of postcode districts in north-west England, which are subdivisions of four post towns. These cover most of Merseyside (including Liverpool, Bootle and Prescot), part of west Lancashire (including Ormskirk) and a small part of north-west Cheshire. In 1999, postcodes for the Wirral Peninsula (L41-49, 60-66) were transferred to the CH postcode area.
