About CodePostalPro
The modern global reference for postal codes and geographic data.
CodePostalPro.com served for years as a French-language postal-code reference. It was rebuilt in 2026 as a global directory on a single normalised database, with one goal: accurate, sourced, fast pages — no advertising, no filler. English is the primary edition; each country is also published in its own administrative language where that differs.
What you will find
- postal and ZIP code lookup from a city, locality or region — and the reverse;
- browsing pages by country and region, with complete code lists;
- for each locality: administrative hierarchy, postal code, coordinates, time zone, and where available demographics and telephone area codes — each with its source and verification status;
- a free JSON API and MCP server over the same data.
Countries covered
CodePostalPro is expanding country by country as reliable postal and geographic sources are identified, normalised and verified. Current coverage includes the United States, France, Algeria, Tunisia and Morocco, with additional countries being added continuously. Each country is described in its own terms — states and ZIP codes, départements and communes, wilayas and post offices — rather than forced into one template.
Transparency
The sources and methodology are public. Every value on the site is traceable to a named dataset with its licence and date. National postal operators remain the official reference.
