PH1 postcode district

Postcodes and sectors

Roads filed under PH1

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 PH1

What does a PH1 postcode tell you?

That the address lies in the PH1 district of the PH (Perth) postcode area, and the place OS Open Names most often lists first for its postcodes is Perth. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 1,253 live postcodes.

What each figure means, and what a district page never says, is set out in Reading a British postcode district page; the glossary defines a postcode district, a postcode area, a postcode directory and a street register.
