# Set the runtime locale manually

<!--todo: The Angular CLI sets the locale ID token as part of the translation. -->

<!--todo: To override the provider for the locale ID token. -->

The initial installation of Angular already contains locale data for English in the United States \(`en-US`\).
The [Angular CLI][AioCliMain] automatically includes the locale data and sets the `LOCALE_ID` value when you use the `--localize` option with [`ng build`][AioCliBuild] command.

To manually set the runtime locale of an application to one other than the automatic value, complete the following actions.

1.  Search for the Unicode locale ID in the language-locale combination in the [`@angular/common/locales/`][UnpkgBrowseAngularCommonLocales] directory.
1.  Set the [`LOCALE_ID`][AioApiCoreLocaleId] token.

The following example sets the value of `LOCALE_ID` to `fr` for French.

<code-example header="src/app/app.module.ts" path="i18n/doc-files/app.module.ts" region="locale-id"></code-example>
