TheCR postcode area, also known as theCroydon postcode area,[2] is a group of eight postcode districts inEngland, within tenpost towns. These cover parts of southernGreater London and north-eastSurrey.
The mainsorting office is in Croydon, and the area served includes most of theLondon Borough of Croydon, the southeastern part of theLondon Borough of Merton and small parts of the London Boroughs ofSutton andBromley. Most of CR3 and CR6 cover the northern part of theTandridge district of Surrey, and the southern part of CR5 covers a small part of the borough ofReigate and Banstead.
Croydon was the second town, afterNorwich, to haveexperimental postcodes, introduced in 1966. This trialled the postcode area CRO (letter 'O'), while Norwich used NOR for its equivalent. It was decided that the outward (first) part of a postcode should be alphanumerical, so CRO became CR0 (with a zero) and NOR became NR1. The CR1 postcode has not been introduced, making CR the only postcode area with a district 0 but not a district 1.
Originally there were only the districts CR0, CR2, CR3 and CR4 - in the 1990s CR5 was split from CR2, CR6 and CR8 were split from CR3, and CR7 from CR4.
The CR0 postcode district covers the largest population in the UK.[3]
