OSM Post Office Progress in the 'SL' Postal Area

Comparison of POL data from 2023‑09‑27 and OSM data from 2024‑04‑17 09:00:00 Z. The blue circles on the map are Post Office branches from the official list that haven't been matched to an OSM amenity=post_office object. The red circles are OSM amenity=post_office objects that haven't been matched to a branch on the official list. Pale blue circles are 'home service' branches (for which it's not clear if they should be mapped) and banches that were marked as 'temporarily closed' at the date of the official data. Pale red circles indicate an OSM object that has been identified as non-Post-Office-Ltd business that may still be correctly tagged as amenity=post_office. The green lines represent matches from the official data to OSM amenity=post_office objects (dark green for a match via a ref:pol_id tag, light green for a proximity match). For more information on how to use this map/data to improve OSM, see the Mapping Notes. For more data on the matched/unmatrched objects, see the tables below.

Post Offices on the POL list not matched to an OSM Object

These branches are listed in the official data but do not appear to have a correstponding amenity=post_office object in OpenStreetMap. The data may be sufficient to be able to add the branch directly, but a survey would normally be preferable to ensure the branch and its relation to its surroundings are mapped accurately.

OSM Objects not matched to a Post Office on the POL list

These are entries are OSM objected tagged with amenity=post_office, which have not been matched to a branch on the official list. Entries here could be due to: Former branches that have now closed, more than one object being tagged for a single post office, the official entry for a real Post Office being matched incorrectly to a different OSM object, other non-Post-Office outlets bing tagged with amenity=post_office. Not all of these entries will be errors in the OSM data, so be careful before making any edits. See the mapping notes.

Post Offices on the POL list matched to an OSM object by location

OSM objects tagged with amenity=post_office that have been matched to a branch on the official list by their location. If you can confirm the match, please add the appropriate ref:pol_id=* tag. But please do not rely on the location alone — some of the locations in the POL data are significantly displaced, or have not been updated following branch moves. See the mapping notes.

In the tables above the different letters in the 'Tags' column denote the presence of the following tags on the OSM object: a addr:housename=* or addr:housenumber=*; s shop=*; n note=*; f fixme=*. The purpose of these flags is to suggest when there might be sufficient information to make a positive match with the POL data, and to highlight any objects that may need checking.
