Which countries are supported?

Many, including the US, UK, Germany, France, Canada, Australia, Spain, Italy, Netherlands, Brazil and India. Choose the country first, then enter its postal code format.

Why does my postal code return no result?

A "not found" result means the code is not in the dataset for the selected country. Check you picked the right country and entered the code in its expected format (e.g. 5 digits for the US).

Yes. Postal code lookups are completely free with no sign-up, powered by the open Zippopotam.us API.

What do the latitude and longitude represent?

They are the approximate centre point of the postal-code area, useful for mapping or geocoding rather than pinpointing a precise street address.

Can one postal code map to several places?

Yes. Some codes cover more than one locality, so the tool lists every place name returned for that code along with its state and coordinates.

Do I need to format the postal code in a special way?

Enter the code in the country's normal format — five digits for the US, the outward and inward parts for the UK, and four or five digits for most of Europe.

How to use ZIP / Postal Code Lookup

The ZIP / Postal Code Lookup finds the location behind any postal code. Choose a country, enter the code, and the tool returns the matching city or place name, the state or region, and the precise latitude and longitude. It covers the United States, United Kingdom, Germany, France, Canada and many more — useful for shipping, form validation, geocoding, research and travel planning.

Select the country from the dropdown (codes follow the two-letter ISO standard).
Type the ZIP or postal code in that country's usual format.
Press Look up (or hit Enter) to query the Zippopotam.us API.
Read the place name(s), state or region, and latitude/longitude in the results.

Your query is sent to Zippopotam.usto fetch results. We don't store it.

Postal code formats around the world

Every country structures its postal codes differently, which is why you must pick the country first. The United States uses a five-digit ZIP code (optionally a nine-digit ZIP+4). The United Kingdom uses an alphanumeric postcode split into an outward and inward part, such as SW1A 1AA. Germany and France use five digits, while the Netherlands combines four digits with two letters. Entering a code in the wrong format — or for the wrong country — is the most common reason a lookup returns no result.

Sample postal code formats
Country	Format	Example
United States	5 digits	90210
United Kingdom	Alphanumeric	SW1A 1AA
Germany	5 digits	10115
Netherlands	4 digits + 2 letters	1011 AB
Canada	Alphanumeric	M5H 2N2

What the lookup returns and its limits

For a valid code the tool returns the post code, the country and its abbreviation, and one or more places — each with a place name, state or region (with abbreviation where provided), and latitude/longitude. The coordinates mark the centre of the postal area rather than an exact address, so they are ideal for mapping and rough distance work but not for navigation to a specific building. A "not found" response simply means the code is absent from the dataset for the selected country; double-check the country and the code format and try again.
