Supported Languages and Locales

Supported Languages

CLEAR currently supports the following languages:

• English (en)
• Spanish (es)
• French (fr)
• German (de)
• Italian (it)

Supported Locales

CLEAR supports both language-only and region-specific locales:

• en-US
• en-MX
• en-CA
• es-MX
• es-US
• fr-CA
• en
• es
• fr
• de
• it

Locale Selection Priority

CLEAR determines which language/locale to display using the following order of precedence:

1. Previously Selected Locale

   If the user has already selected a locale in a prior CLEAR experience, that setting is reused.

2. Browser Language Settings

   If no prior selection exists, CLEAR reads the user’s browser language preferences and selects the best match.

3. API-Provided Locale

   If your integration includes a locale value in the create_verification_session API request, this will override browser settings.

4. Default Fallback

   If none of the above are available, CLEAR defaults to:

en (English)

Forcing a Locale via URL

You can explicitly control the language of the CLEAR verification flow by passing a query parameter in the URL:

&cv_locale=<locale>

Example

To launch the flow in Spanish:

&cv_locale=es

You can also use region-specific values if needed:

&cv_locale=es-MX
&cv_locale=fr-CA

Best Practices

• Prefer passing a locale explicitly if your app already knows the user’s language.
• Use language-only codes (es, fr) unless regional differences matter.
• Avoid conflicting signals (e.g., passing locale in API + different cv_locale in URL).
• Always ensure a fallback experience (CLEAR will default to English automatically).
