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 Swindon, Chippenham, Calne, Corsham, Devizes, Malmesbury, Marlborough, Melksham and Pewsey), plus a small part of south-west Oxfordshire (including Faringdon) and a very small part of Gloucestershire.
