INTERNATIONAL POSTAL CODE LOOKUP

Postal Code Lookup

Find your postal code from your address, or type a postal code to see every address behind it — from the same reference data our Address Validation API uses.

  • 21 countries in one dropdown, from Armenia to the United States.
  • Search by address or by postal code — either direction, same data.
  • Free to try right here. No signup for your first lookups.

Look up an address or a postal code

What a lookup returns

A postal code is rarely one place. Depending on the country it can cover a single street, a whole town, or several towns at once — so the lookup hands you the answer in three steps instead of one flat list.

StepWhat you see
postal codeEvery city or locality that uses this postal code, with the number of addresses in each. When only one city uses it, you skip straight to the streets.
cityEvery street in that city under this postal code, with the number of addresses on each.
streetThe house numbers on that street, each as a full line: house number, street, postal code and city.

The same address records are what the Address Validation API and the Geocoding API read, so what you see here is what your integration will get.

Countries in the lookup

Armenia, Austria, Belgium, Canada, Costa Rica, Czechia, Denmark, Finland, France, Germany, Italy, Luxembourg, Mexico, Netherlands, Portugal, Serbia, Singapore, Spain, Sweden, Switzerland and the United States.

The United Kingdom is served separately from the Royal Mail Postcode Address File — use the UK Postcode Lookup for those. Address Validation and geocoding cover far more countries than this browser lookup does; see the coverage map.

Need this in your own code?

The browser lookup is here to try. When you want postal codes resolved inside your checkout, CRM or data pipeline, that is the Address Validation API — free key, no credit card.
