Post Towns in Mid Sussex
Below is a list of post towns in Mid Sussex, grouped by postcode area:
- BN ▸ Hassocks (BN6)
- RH ▸ Burgess Hill (RH15) ⁞ East Grinstead (RH19) ⁞ Haywards Heath (RH16 / RH17)
The UK postal hierarchy begins with broad postcode areas (such as “CB” or “M”), which are divided into smaller postcode districts (such as “CB8” or “M1”) to support accurate mail routing. Each postal address is anchored by a designated post town, the official locality name used in the UK postcode system, which operates independently from Local Authority Districts —the administrative boundaries used for council tax and local government services. Because they serve different purposes, a property’s postal address and its local authority district do not always align exactly.
