# Country list – sources and licenses

The built-in country list (inside `country-select.js` and in `data.json`) is generated by
`scripts/build-data.js` (`npm run build:data`) from:

| Field | Source | License |
| --- | --- | --- |
| Country codes | ISO 3166-1 alpha-2 (public standard) + `XK` (Kosovo, user-assigned code in common use) | – |
| English names | [Unicode CLDR](https://cldr.unicode.org/) – through the `Intl.DisplayNames` API (ICU); `&` / `St.` written in full and a few common short names (e.g. *Hong Kong*, *Myanmar*, *DR Congo*) | Unicode License V3 (below) |
| Calling codes | ITU-T E.164 assignments (public standard), checked against [libphonenumber-js](https://github.com/catamphetamine/libphonenumber-js) (MIT), whose metadata comes from Google's [libphonenumber](https://github.com/google/libphonenumber) (Apache-2.0) | – |
| Other names (search) | Former / official ISO names (e.g. *Turkey*, *Ivory Coast*, *Korea, Republic of*) | – |

Translated country names (`data-lang`) are produced at runtime by the browser's own `Intl.DisplayNames` (CLDR) and are not stored.

The flags in `flags/` are from flag-icons – see `flags/LICENSE`.
