IP3 postcode district

Postcodes and sectors

765 of the district's 917 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 52.04132, 1.18808, which locates the district, not a building.

Companies registered in IP3

Companies House lists 2,194 companies with a registered office in IP3; 207 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 IP3

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 IP3

What does an IP3 postcode tell you?

That the address lies in the IP3 district of the IP (Ipswich) postcode area, and the place OS Open Names most often lists first for its postcodes is Ipswich. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 765 live postcodes.
