DL10 postcode district

Postcodes and sectors

Roads filed under DL10

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 DL10

What does a DL10 postcode tell you?

That the address lies in the DL10 district of the DL (Darlington) postcode area, and the place OS Open Names most often lists first for its postcodes is Richmond. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 842 live postcodes.
