Map data sources and coverage

Current live mapped data

Loading current source editions…

Each live dataset lists its publisher, licence, current source and checksum. OpenStreetMap-derived layers also include the exact transformation program used to create the searchable data. Official registers are stored with their source release. Missing postcodes remain blank, never inferred. Number ranges remain as mapped.

© OpenStreetMap contributors. The separate address dataset is available under the Open Database Licence 1.0.

Source: Geofabrik UK snapshot, 13 October 2026. Includes Great Britain and Northern Ireland; excludes Channel Islands and Isle of Man. Community coverage is incomplete. No postcode or house number is inferred. Ranges and units remain as mapped. Geometry centres are approximate, not entrances.

Download the complete normalized address dataset (compressed JSON Lines, about 102 MiB). SHA-256: bf3213d83cf490fda530daad250a9c1861817158c2833779cc5e3f27beb566a0. Includes 5,612,841 source objects; these are not necessarily unique postal addresses.

To reproduce the complete normalized dataset, download the source above and the transformation program (also ODbL 1.0 for this purpose). With Python 3, pyosmium and osmium-tool installed, place both in one directory and run:

osmium tags-filter united-kingdom-261013.osm.pbf nwr/addr:postcode -o address-objects.osm.pbf
python3 prepare_addresses.py .

This produces addresses.jsonl.gz containing the entire address layer, and a manifest of checksums and counts. No additional private data is used in this transformation. Each record retains its OSM object identity. OGL geography and inferred identifier links remain separate.

Archived amenities and local businesses snapshot

The separate OpenStreetMap amenity layer contains 425,985 mapped objects, including post offices and postal partners, pharmacies, cafés, restaurants, pubs, banks and a wider range of mapped shops, including convenience stores, bakeries, clothing shops and hairdressers. Coverage is incomplete and opening status is not verified. Relations without coordinates are excluded. Building/site centres are approximate. Nearby search uses distance from a named place or postcode centre, not administrative containment.
