# Adjust language & default country code

humanID is available in 26 languages (and if your language is not supported, please submit a push request with translations via our github). The 'country code' preselected can also be adjusted, and if your users come from a handful of countries, those can be shown on top of the list.

To adjust the language and 'priority countries' of the user frontend, humanID integration partners can set URL parameters. Users can also manually change the language from a dropdown.

Here is how:
