Dorset Postcode Areas, Districts and Map Guide

Dorset is a ceremonial county in South West England, famous for its stunning coastline, rolling countryside, historic market towns, and popular seaside resorts. The county includes much of the Jurassic Coast, a UNESCO World Heritage Site, and is known for its tourism industry, maritime heritage, and attractive rural communities.

Dorset is primarily covered by the DT (Dorchester) and BH (Bournemouth) postcode areas, with smaller sections using postcode districts from neighbouring counties. These postcode areas help organize mail delivery, local government services, transport planning, business operations, emergency response, and property administration.

Overview of Dorset Postcode Areas

Dorset is mainly served by two postcode areas:

BH (Bournemouth) – Covers Bournemouth, Poole, Christchurch, Wimborne, Ferndown, and much of eastern Dorset.
DT (Dorchester) – Covers Dorchester, Weymouth, Bridport, Sherborne, Blandford Forum, and much of central and western Dorset.
