240+ Country Pages: Find Your Country's Postal Code Format in One Click
Every country has its own postal code format, its own quirks, and its own terminology. Germany calls them Postleitzahlen. Japan formats them as NNN-NNNN. Ireland uses 7-character Eircodes that look nothing like what you would expect. Brazil uses 8-digit CEP codes. The Netherlands mixes digits and letters.
If you are building an application that handles addresses internationally, you need to know these formats — for validation, for display, for user experience.
One Page Per Country
We just published dedicated pages for 240+ countries and territories at postaldatapi.com/countries. Each page includes:
- Format reference — what the postal code looks like (e.g., NNNNN, ANA NAN, NNN-NNNN)
- Regex pattern — copy-paste validation for your forms
- Example postal code — a real code you can test with
- Local terminology — what locals actually call it (PLZ, CEP, PIN code, Eircode, postcode, ZIP code)
- Live API examples — working cURL, Python, and Node.js code with country-specific parameters
- Pricing — same $0.000028 per query regardless of country

Why This Matters for Developers
Most postal code APIs document their coverage in a single table or a FAQ answer. That is fine for "do you support my country?" but it does not help when you need to know the format, build a regex, or write country-specific validation logic.
These pages are designed to be the reference you bookmark. One page per country, everything you need to integrate that country's postal codes, and a working API example you can run right now.
Rich Metadata Too
Every country page links to the same API that returns up to 18 metadata fields per postal code — timezone, administrative regions, elevation, coordinates, and more. The country pages show you the format; the API gives you the full picture.
