RM17 postcode district

Postcodes and sectors

Roads filed under RM17

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 RM17

What does an RM17 postcode tell you?

That the address lies in the RM17 district of the RM (Romford) postcode area, and the place OS Open Names most often lists first for its postcodes is Grays. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 533 live postcodes.
