The PE postcode area, also known as the Peterborough postcode area, is a group of postcode districts covering a large area in eastern England, including Peterborough, Huntingdon and St. Neots in Cambridgeshire, King's Lynn in Norfolk and Boston and Stamford in Lincolnshire. Parts of East Northamptonshire also have the postcode instead of the NN postcode. Her Majesty the Queen's private house at Sandringham in north-west Norfolk has a PE post code.
