DA1 postcode district

Postcodes and sectors

1,266 of the district's 1,992 postcodes are live in the ONS Postcode Directory of August 2026. A postcode directory says whether a code is in use, never who is there. The live postcodes centre on 51.44809, 0.20953, which locates the district, not a building.

Roads filed under DA1

Named roads first, then numbered ones. A road is filed under one district even where it runs through several, so a street missing here may be listed under a neighbouring district — which is why the address lookup never calls a British street absent. Great Britain has no open register of buildings, so a listed road never means a building on it exists.

Common questions about DA1

What does a DA1 postcode tell you?

That the address lies in the DA1 district of the DA (Dartford) postcode area, and the place OS Open Names most often lists first for its postcodes is Dartford. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 1,266 live postcodes.

What each figure means, and what a district page never says, is set out in Reading a British postcode district page; the glossary defines a postcode district, a postcode area, a postcode directory and a street register.
