The WD postcode area, also known as the Watford postcode area, is a group of eleven postcode districts in England, within seven post towns. These cover south-west Hertfordshire, plus very small parts of Buckinghamshire and Greater London.
Mail for this area is sorted at the Home Counties North Mail Centre in Hemel Hempstead, having been sorted at the Watford Mail Centre until its closure in 2011. The area covered includes all of the borough of Watford, most of the Three Rivers district, the western part of the Hertsmere district and small parts of the Dacorum and St Albans districts. WD3 also covers the village of Chenies in the Chiltern district of Buckinghamshire, plus a small protrusion of Harefield in the London Borough of Hillingdon.

In September 2000 districts WD17-19 and WD23-25 were created from the recoding of the WD1 and WD2 districts. BUSHEY is a new post town; having previously been part of the WD2 district of WATFORD. This was due to postcode exhaustion of WD1 and WD2  Another reason for the postcode revision was the old WD2 area included Bushey with North Watford. Bushey was to all intents a section of Watford sorting office; up until 2000, all mail for WD2 was cut and tipped at Watford office. In order to change this, new codes were created to enable direct bags to be opened at Bushey delivery office.
