What does a GL16 postcode tell you?

That the address lies in the GL16 district of the GL (Gloucester) postcode area, which the directory places around Forest of Dean. The inward half of the full postcode narrows it to a street or a building; the district alone does not, and an address written with a district and no inward half cannot be checked against the register.

Does a street listed here mean an address on it exists?

It means OS Open Names lists a road of that name under the district, which is what the address lookup answers as a street-level match. It says nothing about any building on it: Great Britain publishes no open register of buildings, so the lookup answers exists: null there and confirms the street alone.

Who lives at these postcodes?

Nobody on this page. A postcode directory says whether a code is in use, never who is there, and a streets register lists roads, not occupants. The address lookup carries no field about a person and never will.

GL16 postcode district

What the public directories installed here say about the GL16 postcode district: how many of its postcodes are in use, the places OS Open Names lists for them, the streets it files under the district and the district's centroid. Counted from the national postcode directory and OS Open Names on 2026-09-18, and never about who is at an address.

Places the directory lists for GL16

OS Open Names places the district's postcodes in these settlements, boroughs, counties and regions, most often first. A town written as any of them matches the directory in an address lookup, and one written as another place in the GL area is reported but not scored.

Postcodes in use

500 postcodes in GL16 were in use on the day of the count. A postcode directory says whether a code is in use, never who is there. 84 of its 584 postcodes have been terminated: a real address written with one has moved on, which is not the same thing as a typo, and the address lookup scores it rather than refusing it.

Centroid: 51.79578, -2.61289 — the mean of the live postcodes' centroids, which locates the district, not any building in it.

Streets filed under GL16

OS Open Names files 292 roads under GL16. 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.
