PO8 postcode district

Postcodes and sectors

873 of the district's 1,064 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 50.91349, -1.01162, which locates the district, not a building.

Companies House lists 2,983 companies with a registered office in PO8; 233 of them at addresses shared by 25 or more companies (1 October 2026 snapshot). 25 is the count at which the address lookup reports a company cluster.

Roads filed under PO8

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 PO8

What does a PO8 postcode tell you?

That the address lies in the PO8 district of the PO (Portsmouth) postcode area, and the place OS Open Names most often lists first for its postcodes is Horndean. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 873 live postcodes.
