+title: D1 can restrict data localization with jurisdictions
+description: A D1 database can set a jurisdiction at creation, which limits the location to run and store the database.

+
+You can now set a [jurisdiction](/d1/configuration/data-location/) when creating a D1 database to guarantee where your database runs and stores data. Jurisdictions can help you comply with data localization regulations such as GDPR. Supported jurisdictions include `eu` and `fedramp`.
+
+A jurisdiction can only be set at database creation time via wrangler, REST API or the UI and cannot be added/updated after the database already exists.
+
+```sh
+npx wrangler@latest d1 create db-with-jurisdiction --jurisdiction eu

 ## Automatic (recommended)
 
 By default, D1 will automatically create your primary database instance in a location close to where you issued the request to create a database. In most cases this allows D1 to choose the optimal location for your database on your behalf.
 
+## Restrict database to a jurisdiction
+
+Jurisdictions are used to create D1 databases that only run and store data within a region to help comply with data locality regulations such as the [GDPR](https://gdpr-info.eu/) or [FedRAMP](https://blog.cloudflare.com/cloudflare-achieves-fedramp-authorization/).
+
+Workers may still access the database constrained to a jurisdiction from anywhere in the world. The jurisdiction constraint only controls where the database itself runs and persists data. Consider using [Regional Services](/data-localization/regional-services/) to control the regions from which Cloudflare responds to requests.
+
+:::note
+
+Jurisdictions can only be set on database creation and cannot be added or updated after the database exists. If a jurisdiction and a location hint are both provided, the jurisdiction takes precedence and the location hint is ignored.
