AddThis supports localization in many languages. By default the language used is determined by the user’s browser settings so you don’t have to do anything to provide localized tools to your users.

Note: Content you add to the tools, such as related post titles and audience targeting messages will not be automatically localized.

Available Languages

Here are the languages currently supported by AddThis, along with the two letter code that you can use in configuration to specify the language.

Overriding Default Localization

If you would like to override a user’s default browser localization, you can use this code to specify the two-letter code from the table above. Just add this anywhere on the page:

<script type="text/javascript">
var addthis_config = addthis_config||{};
addthis_config.lang = 'es' //show in Spanish regardless of browser settings;
</script>
