PO41 postcode district

Postcodes and sectors

151 of the district's 170 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 50.70095, -1.47512, which locates the district, not a building.

Roads filed under PO41

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 PO41

What does a PO41 postcode tell you?

That the address lies in the PO41 district of the PO (Portsmouth) postcode area, and the place OS Open Names most often lists first for its postcodes is Yarmouth. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 151 live postcodes.
