SN postcode area

The SN postcode area, also known as the Swindon postcode area, is a group of eighteen postcode districts in England, within ten post towns. These cover north Wiltshire (including the Borough of Swindon, Chippenham, Calne, Corsham, Devizes, Malmesbury, Marlborough, Melksham and Pewsey), as well as a small part of south-west Oxfordshire (including Faringdon) and a very small part of Gloucestershire. Mail for the SN postcode area is processed at Thames Valley Mail Centre in Swindon, along with mail for the OX and RG postcode areas. The approximate coverage of the postcode districts is as follows. The SN25 and SN26 districts were formed out of the SN2 district in 1999.
