# Localized Knowledge falls back within the same language

In Messaging and Email channels, when a Knowledge search finds no articles matching an end user's localized language tag, your AI Agent now uses the remaining articles in that language, including versions localized for other regions. Previously the search returned nothing and the AI Agent replied that it did not have the information. Voice is unchanged.

This closes the gap for end users whose tag carries a region, such as `en-GB` or `en-AU`. End users on a root tag like `en` were already served from all locales for that language.

Availability rules remain the way to keep localized articles with the right end users. Set them on any content that must stay region-specific. See [Knowledge localization](/docs/setup/languages/about-multilingual-support#knowledge-localization).
