N1 postcode district

Postcodes and sectors

2,289 of the district's 3,504 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 51.53776, -0.09697, which locates the district, not a building.

Companies registered in N1

Companies House lists 48,384 companies with a registered office in N1; 40,338 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 N1

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 N1

What does an N1 postcode tell you?

That the address lies in the N1 district of the N (North London) postcode area, and the place OS Open Names most often lists first for its postcodes is London. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 2,289 live postcodes.
