FAQ

Postal Code Lookup questions

Quick answers about postal code searches, coordinates, map clicks, boundaries, and related results.

What's my postal code?
Your postal code is the short code for the area where you live, used on letters, parcels and forms. To find it, type your home address in the search box above and pick it from the list. Or zoom in on the map and click your house or street. The tool shows the postal code for that spot.
How do I find my postal code right now, where I am?
Zoom in on the map and click the place where you are. The tool shows the postal code for that point. If you know your street name, typing it is usually faster.
What is Postal Code Lookup?
Postal Code Lookup helps you find postal code details from an address, postal code, city, coordinates, or map location. Results can include the postal code, city, region, country, coordinates, boundaries, related places, or point locations depending on available open data.
Can I search postal codes outside the United States?
Yes. This postal code lookup page does not filter autocomplete or postal code searches to the United States. Search by address, city, postal code, coordinates, or map click. If you only need US ZIP code details, use ZIP Code Lookup.
Why do some postal codes show boundaries and others show points?
Open postal data varies by country and source. Some postal codes include boundary geometry, while others are available only as representative point locations.
Can I find a postal code from coordinates?
Yes. Enter coordinates as latitude, longitude, for example 51.507351, -0.127758, or click an empty area on the map to search by that point. If you need full address details from coordinates, use Reverse Address Lookup.
How is Postal Code Lookup different from Find ZIP Code?
Postal Code Lookup is for postal-code searches across countries. Find ZIP Code is focused on finding a US ZIP code by address, city, coordinates, or map location.
Can I download postal code results?
Yes. You can copy the main result, copy GeoJSON, save postal codes to a page-local list, and download related places or postcodes as CSV.
Is this official postal authority data?
No. This tool uses open postal and map data. Results are useful for lookup, mapping, data review, and reuse according to source data terms, but they should not be treated as official postal authority records.
