Finding a Place From a ZIP or Postal Code

Enter a ZIP or postal code and pick a country to see the town it belongs to, its state or region and its rough position on a map. In the United States, 90210 is Beverly Hills, California (CA), at about 34.09, -118.41.

Most lookups use Zippopotam.us, a free service built on GeoNames postal data, which covers 70 countries. Coverage is uneven. Canada has only the first three characters of each code, such as M5V. Great Britain has only the first half, such as SW1A, and Brazil lists only major codes. One code can also cover several places, which is common in France and Spain, so the tool lists them all. In the US, the town shown is the USPS recommended name, which may differ from the town you use.

Full UK postcodes like SW1A 1AA go to Postcodes.io instead. It returns the district, ward, region, parliamentary constituency and grid position from Ordnance Survey and ONS data. Northern Ireland postcodes, which start with BT, are the exception. Their full data needs a commercial licence, so the tool looks them up by the first half.

Switch to By city to go the other way. Enter a region code and a town, such as CA and Beverly Hills, to list its codes. Each place links to OpenStreetMap, and the coordinates are centre points, not addresses. Only the country and the code or place name leave your browser. To see where your own connection appears to be, try IP Address Info.

Frequently Asked Questions

Yes. In the US, a single ZIP code often serves several towns, and USPS names one of them as the recommended city, which is what this tool shows. Elsewhere, codes are often shared openly: a French or Spanish code can list several villages. In those cases the tool shows every place returned for the code.
The free data only includes the first three characters, called the forward sortation area, for copyright reasons. So M5V 3L9 is looked up as M5V, which covers part of downtown Toronto. The full six-character code narrows it to a block or a building, but that data is licensed by Canada Post.
Full UK postcodes are looked up with Postcodes.io, which uses open data from Ordnance Survey and the Office for National Statistics. That adds the council district, ward, region and parliamentary constituency. Northern Ireland BT postcodes are looked up by their first half instead, because full BT data needs a commercial licence.
They mark a centre point for the code or place, not a street address. For a small UK postcode that is usually within a few hundred metres. For a large rural US ZIP code, or a code shared by several villages, the point can be several kilometres from where a given address is. Use them for maps and rough distances only.
70 countries and territories, including the US, Canada, the UK, Germany, France, Spain, Italy, the Netherlands, Japan, India, Australia, Mexico and Brazil. Some are partial, as with Canada and Brazil. Ireland, China and most of Africa are not included. Pick the country from the list; the example under the code field shows its format.
