What does an SY12 postcode tell you?

That the address lies in the SY12 district of the SY (Shrewsbury) postcode area, and the place OS Open Names most often lists first for its postcodes is Ellesmere. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 381 live postcodes.

Postcodes and sectors

381 of the district's 433 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 52.90313, -2.89469, which locates the district, not a building.

Roads filed under SY12

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.
