Locations for Realtime Database

When you provision a Realtime Database instance, you must choose a location for the instance. To reduce latency and increase availability, store your data close to the users and services that need it.

If your project is on the pay-as-you-go Blaze pricing plan, then you can optionally create multiple databases in your project, each with its own location setting.

Be aware that once you provision a database instance, you cannot change its location setting.

In the following table, find the supported locations for Realtime Database instances along with their associated database URL formats.

Region name	Region description	Database URL format
us-central1	Iowa	DATABASE_NAME.firebaseio.com
europe-west1	Belgium	DATABASE_NAME.europe-west1.firebasedatabase.app
asia-southeast1	Singapore	DATABASE_NAME.asia-southeast1.firebasedatabase.app
