RM10 postcode district

Postcodes and sectors

583 of the district's 815 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 51.54489, 0.15791, which locates the district, not a building.

Roads filed under RM10

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 RM10

What does an RM10 postcode tell you?

That the address lies in the RM10 district of the RM (Romford) postcode area, and the place OS Open Names most often lists first for its postcodes is Dagenham. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 583 live postcodes.
