IP12 postcode district

Postcodes and sectors

1,057 of the district's 1,323 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 52.09334, 1.37025, which locates the district, not a building.

Roads filed under IP12

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 IP12

What does an IP12 postcode tell you?

That the address lies in the IP12 district of the IP (Ipswich) postcode area, and the place OS Open Names most often lists first for its postcodes is Woodbridge. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 1,057 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.
