|Statistics as at May 2020|
The DA postcode area, also known as the Dartford postcode area, is a group of eighteen postcode districts in England, within eleven post towns. These cover parts of south-east London and north-west Kent.
The main sorting office in Dartford ceased operating in 2012 and became a Delivery Office. The area served includes most of the London Borough of Bexley and very small parts of the London Borough of Bromley and the Royal Borough of Greenwich, while in Kent it covers almost all of the Borough of Dartford, most of the Gravesham district, the northeastern part of the Sevenoaks district and a very small part of the borough of Tonbridge and Malling.
