# Localization and user properties

The following properties can be set on the user resource to select the language presented to end users for some PingOne interface elements.

* `locale`

  This is the user's default location. This property may be explicitly set to null when updating a user to unset it. It is used for localizing such items as currency, date time format, or numerical representations. If provided, it must be a valid language tag as defined in [RFC 5646](https://www.rfc-editor.org/rfc/rfc5646.html).

* `preferredLanguage`

  The user's preferred written or spoken languages. This may be explicitly set to null when updating a user to unset it. If provided, the format of the value must be a valid language range and the same as the HTTP Accept-Language header field (not including Accept-Language:) and is specified in [Section 5.3.5 of RFC 7231](https://datatracker.ietf.org/doc/html/rfc7231#section-5.3.5). For example: en-US, en-gb;q=0.8, en;q=0.7.
