What Zipdress does
Click any spot on the map and Zipdress shows its street address and postal code. You can also search for a country, a city, a ZIP code or an address. Every country has a page with its postal code format and the way an address is written there, and larger cities have a page that lists their postal codes.
The site is free to use and needs no account.
Where the data comes from
- Addresses and map: OpenStreetMap contributors (ODbL).
- Address lookup: Geoapify, with Nominatim as a fallback.
- Cities and postal codes: GeoNames (CC BY 4.0) and OpenStreetMap.
- Postal code and address formats: Google libaddressinput.
- Borders and disputed areas: Natural Earth (public domain).
Disputed areas
Areas whose status is disputed are hatched on the map. Their notes say who administers each area and who claims it, and which postal service delivers mail there.
Accuracy
Open data is good but not perfect: a postal code can be missing, out of date or assigned to a neighbouring area. Before you send anything important, check the code with the national postal service. If you find a mistake in an address, you can report or fix it on OpenStreetMap, and the correction reaches Zipdress with the next data update.
