Frequently asked questions

What is an ISO alpha-2 / alpha-3 code?

These are standardized short codes defined by ISO 3166-1 for identifying countries — alpha-2 is the 2-letter form used in domains and country selectors (e.g. "DE" for Germany), and alpha-3 is the 3-letter form often used in data formats and shipping/customs systems (e.g. "DEU"). This tool shows both for every country so you can grab whichever your project needs.

Where does this data come from, and can I trust it?

This tool uses the open "mledoze/countries" dataset (licensed under ODbL 1.0), a widely-used, community-maintained database sourced from ISO standards, currency authorities, and Wikipedia. It's a reliable reference for everyday development use, but for legally-binding or high-stakes decisions (e.g. international shipping compliance), always cross-check against an authoritative primary source.

Does this send my searches anywhere?

No. The full country dataset loads once into your browser, and every search happens locally on your device — nothing is sent to any server. After the first load, it even keeps working offline.
