About Postal Code Finder

Who is behind the site

The site is a project of Directory.bg Ltd., the company behind the Directory.bg business directory and WhatTimeIsIt.zone, where you can see the exact local time of every place listed here.

The site is free and needs no registration. We do not sell data and we do not use advertising cookies. We count visits with Statcounter and Google Analytics only if you allow it in the cookie banner (see the Privacy policy).

Where the data comes from

• Postal codes: GeoNames (CC BY 4.0 license), which collects them from the postal services and statistical offices of each country.
• United Kingdom: the ONS Postcode Directory from the Office for National Statistics (Open Government Licence v3.0): current and terminated postcodes with their local authority and ward.
• Sofia: the neighborhoods for each postal code are from ekatte.info.
• Places, regions and names: GeoNames (CC BY 4.0 license), the same as on WhatTimeIsIt.zone, so a place has the same address on both sites.
• Maps: OpenFreeMap with data from OpenStreetMap (ODbL license), shown with MapLibre GL JS.

The site has the postal codes of more than 100 countries and territories, and more are being added. Some countries are not on the site. Canada is left out because Canada Post claims copyright in its postal codes. For a few others (Ireland, Brazil, China and others) the free data has only part of each code, and we would rather show nothing than a wrong code.

How often it is updated

• Postal codes from GeoNames: every month.
• United Kingdom postcodes: every three months, with each new edition of the ONS Postcode Directory.
• Page addresses never change. A code that is withdrawn leads to the place or district it belonged to.
