The PR postcode area, also known as the Preston postcode area,[2] is a group of eleven postcode districts in North West England, within four post towns. These cover south-west Lancashire (including Preston, Chorley and Leyland) and north Merseyside (including Southport).
The PR25 and PR26 districts were formed out of the PR5 district in January 2001. Leyland became a new post town at this time, having previously been part of the Preston post town.[4]
