## Globalization in Commerce

When describing the language concept in Optimizely, the following language setting types are mentioned:

  • **System language**. Controls date/time formatting, sort order, and so on.

  • **User interface language**. Controls the localized (translated) resources to display; determines the user interface language.

  • **Content language**. The preferred language when displaying content. Content can be a page, a block, or a product catalog item.

Conceptually, globalization in Optimizely Customized Commerce works the same way as in Optimizely Content Management System (CMS). To learn about language management, see [Globalization](🔗).

## Localization

By default, the Customized Commerce user interface is available in a number of languages. You can localize it further with additional languages.

### Commerce user interface

You localize the Customized Commerce pluggable add-on user interface using the Optimizely localization services in the same way that the CMS does. See also [Localization service](🔗).

### Order data


This feature applies to Customized Commerce version 13.21 and higher.

By default, the localization of order data is enabled. If you do not use order data localization, you can disable it. Disabled order data localization saves storage and improves performance by reducing read/write operations.

To disable order data localization, set the OrderOptions DisableOrderDataLocalization to true in_appsettings.json_ or inside ConfigureServices method of _Startup.cs._
