BR3 postcode district

Postcodes and sectors

Roads filed under BR3

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 BR3

What does a BR3 postcode tell you?

That the address lies in the BR3 district of the BR (Bromley) postcode area, and the place OS Open Names most often lists first for its postcodes is Beckenham. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 1,125 live postcodes.
