What each declared coverage means:

- Geocoded National Address File (G-NAF) (Australia, complete): The end user licence forbids using the file to build a mailing list or send unsolicited mail; an address is checked against it, never listed from it.
- BeST Address — Brussels (Belgium — Brussels, complete): Complete for its region; the three regional files together are the country.
- BeST Address — Flanders (Belgium — Flanders, complete): Complete for its region; the three regional files together are the country.
- BeST Address — Wallonia (Belgium — Wallonia, complete): Complete for its region; the three regional files together are the country.
- Cadastro Nacional de Endereços para Fins Estatísticos (CNEFE) (Brazil, partial): Marked partial here because it is the address list of the 2022 census, a snapshot rather than a maintained register. A building finished since the census is absent, so absence is never read as 'not there'. 27 of its 27 files are installed.
- Danmarks Adresseregister (DAR) (Denmark, partial): Marked partial here because its copy is no longer refreshed. The copy was taken on 26 September 2026 through DAWA, the address web API Klimadatastyrelsen closed on 1 October 2026, so an address created since then is not in it, and until the register is read from its new distribution an address it lacks is never answered as absent. Denmark only: Greenland and the Faroe Islands keep registers of their own.
- Base Adresse Nationale (France (with Guadeloupe, Martinique, French Guiana, Réunion, Mayotte, St. Pierre & Miquelon, St. Barthélemy, St. Martin), partial): Built from the address lists communes publish themselves: on 22 September 2026 the publisher counted 28,632 of France's 35,011 communes with a list of their own, the source of 23.03 million of the 26.1 million addresses it holds, so an address it lacks may sit in a commune whose list is incomplete.
- Adressen Berlin (Germany — Berlin, partial): Marked partial here because it covers one Land, and Germany has no national address register. An address it does not hold, in Berlin or anywhere else in Germany, is never answered as absent.
- Gebäudereferenzen NRW (Germany — North Rhine-Westphalia, partial): Marked partial here because it covers one Land, and Germany has no national address register. The open product carries no postcode, so a building is matched through the town written.
- Hauskoordinaten Rheinland-Pfalz (Germany — Rhineland-Palatinate, partial): Marked partial here because it covers one Land, and Germany has no national address register. The open product carries no postcode, so a building is matched through the town written.
- OS Open Names (Great Britain, partial): Marked partial here because it files each road under one postcode district, though a long road runs through several. Every named and numbered road in Great Britain is in it, as a street: it lists no buildings. A street missing from a district may be filed under a neighbouring one, so it is never denied.
- Official directory of building addresses (Switzerland, complete): The 26 cantons. The file holds no Liechtenstein row, so Liechtenstein is not covered by it.
- National Address Database (United States, partial): States and local governments contribute their address points voluntarily, so an address it lacks may sit in a part that was never shared.
- TIGER/Line address ranges (United States, partial): Marked partial here because not every road edge carries a range, and a street on a ZIP boundary can carry only its neighbour's ZIP. A street it does not know is never denied.

## Postcode directories

| Directory | Countries | Complete | Postcodes | Version | Licence |
| --- | --- | ---: | ---: | --- | --- |
| [ONS Postcode Directory](https://geoportal.statistics.gov.uk/) (`ons-postcode-directory`) | Great Britain | 1 | 2,665,797 | 2026-08 | [Open Government Licence v3.0](https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/) |
| [GeoNames postal codes](https://download.geonames.org/export/zip/) (`geonames-postal-codes`) | 108 countries | 15 | 1,824,519 | 2026-10-17 | [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/) |

- ONS Postcode Directory: Every postcode issued in Great Britain, the Channel Islands and the Isle of Man, live and terminated, with the month each was introduced and terminated. Northern Ireland's BT postcodes are excluded: reusing them needs a Land & Property Services licence.
- GeoNames postal codes: The national postal services' current codes for about a hundred countries in one file. GeoNames lists current codes only, so it never says a code was retired.

A complete directory lists every code its postal operator publishes, so a code it lacks can be answered as not existing; every other directory confirms what it holds and denies nothing. Great Britain's postcodes in numbers: https://spaw.co/tools/address-checker/gb/postcodes

## Reference data behind the town and region checks

Beside the registers and directories, a lookup reads these to decide whether a town or a region written on an address is the postcode's. What is used from them names places, never an address.

| Dataset | Publisher | What it decides | Version | Licence |
| --- | --- | --- | --- | --- |
| GeoNames cities (`geonames-cities`) | [GeoNames](https://download.geonames.org/export/dump/) | The other names a town is written under, in locality_matches_postcode (Munich for München, Moscow for Москва), and the other names of a one-city region, written as the town or as the region, in administrative_area_matches_postcode too (Moscow for Москва); an answer confirmed through one names geonames-cities in its sources, and one whose town and region matched as the directory writes them does not. The same file gives the time zone of the nearest place in IP answers. | 2026-10-03 | [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/) |
| Residential Property Price Register (`ie-property-price-register`) | [Property Services Regulatory Authority (PSRA)](https://www.propertypriceregister.ie/) | Which counties each of the fourteen Eircode routing keys that reach a county of another province, or that GeoNames files under the wrong one (P14), covers, and that D11 and D15 reach into Meath, in administrative_area_matches_postcode for Ireland. | read 2026-09-24 | [PSRA re-use terms](https://www.psr.ie/re-use-of-public-sector-information/) |

- GeoNames cities: Places of 15,000 people or more. A name is compared inside one country and only with the postcode's own places or the name of a one-city region, never with a neighbouring postcode's, and a town's only where the postcode lies within 30 km of the place. A name the directory also lists as a town of its own more than 30 km from the place counts only as the place's own name cut short (Biberach for Biberach an der Riß), so Perlin, a village near Schwerin that the file lists among Berlin's names, does not count for a Berlin code. A name that another listed place of the country also carries is left out, and so are airport codes.
- Residential Property Price Register: The register as last updated on 23 September 2026, read on 24 September 2026: 250,671 of its 807,724 residential sales carry an Eircode, and a county counts for a routing key once it holds at least ten of that key's sales. Only that derived table ships with the code; no sale, address or price is held here. The national file is re-used under the PSRA's terms for the re-use of public sector information (last updated 29 July 2022), which ask for the source and the PSRA's copyright to be acknowledged; data.gov.ie lists only the register's Dublin extract, under CC BY 4.0. The register's download page links those terms as its Re-Use of Information. Source: https://www.propertypriceregister.ie/website/npsra/pprweb.nsf/PPRDownloads?OpenForm

## Company registers and mailbox operators

- 9,520,222 addresses compiled from 8 open company registers (United Kingdom, United States, France, Guadeloupe, Martinique, French Guiana, Réunion, St. Pierre & Miquelon, Mayotte, St. Barthélemy, St. Martin, Wallis & Futuna, French Polynesia, New Caledonia, Norway), version 2026-10-01: they answer companies_registered, the number of companies giving an address as their registered office.
- 9,762 branch addresses published by 6 mailbox operators themselves (United States, Canada, United Kingdom, Ireland): they back is_mail_drop, and an answer names the operator that matched.

## Licensed, and not held

- Royal Mail Postcode Address File (PAF) (United Kingdom): Every full list of British addresses derives from it and reusing it needs a licence, so a British address never answers exists from open data, and the addresses at a postcode are not listed.
- Northern Ireland postcodes (BT) (United Kingdom): Left out of the ONS directory installed here, because reusing them needs a Land & Property Services licence, so the directory holds no BT postcode and an address carrying one is answered as though no directory were installed: postcode_status null, never postcode_not_found.
- The postal service's delivery point data (United States): Whether post is delivered, and the postal service's own agency, vacant and residential flags, are licensed; those fields answer not checked rather than a guess.

## Published elsewhere, not installed here

Address lists these publishers make available, as the publishers describe them. None is installed on this server, so an address there is checked against its format and, where one is installed, a postcode directory. Their terms have not been assessed here.

- Canada: National Address Register, Statistics Canada (https://www150.statcan.gc.ca/n1/en/catalogue/46260002) — a list of commercial and residential addresses in Canada that are extracted from Statistics Canada's Building Register and deemed non-confidential, released semi-annually. Checked on 2026-09-22.
- Estonia: Aadressiandmete süsteem (ADS), Maa- ja Ruumiamet (https://geoportaal.maaamet.ee/est/Ruumiandmed/Aadressiandmed-p112.html) — the central address data system, offered as downloadable extracts and as map services. Checked on 2026-09-22.
- Spain: CartoCiudad, Ministerio de Transportes y Movilidad Sostenible (https://www.cartociudad.es/web/portal) — postal addresses and postcodes among its data, downloadable through the National Geographic Centre. Checked on 2026-09-22.

Nothing on this page says who lives or works at an address: the registers list places, and a lookup against them stores nothing.
