Validate a postal/ZIP code for a country online — 40+ countries, in your browser.
Check whether a postal or ZIP code matches the expected format for its country. Enter the code and a two-letter country code; over 40 countries are supported.
More than 40, including the US, UK, Canada, most of Europe, and major Asian and Latin American countries.
No — it validates the format, not whether the specific postcode exists. That catches the vast majority of input errors.
