PL1 postcode district

Postcodes and sectors

868 of the district's 1,626 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 50.37057, -4.15475, which locates the district, not a building.

Companies registered in PL1

Companies House lists 2,868 companies with a registered office in PL1; 1,025 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 PL1

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 PL1

What does a PL1 postcode tell you?

That the address lies in the PL1 district of the PL (Plymouth) postcode area, and the place OS Open Names most often lists first for its postcodes is Plymouth. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 868 live postcodes.
