You can generally\nselect the region nearest to your app's users, but you should consider [the\nlocations where App Engine is available](/about/locations#region)\nas well as the [locations](/about/locations#region) of the other\nGoogle Cloud products and services that your app uses. Using services\nacross multiple locations can affect your app's latency as well as its\n[pricing](/appengine/pricing).\n\nYou cannot change an app's region after you set it.\n| **Note:** Two locations, which are called `europe-west` and `us-central` in App Engine commands and in the Google Cloud console, are called `europe-west1` and `us-central1`, respectively, elsewhere in Google documentation.\n\nIf you already created an App Engine application, you can view its\nregion by doing one of the following:\n\n- Run the `gcloud app describe` command.\n\n- Open the\n [App Engine Dashboard in the Google Cloud console](https://console.cloud.google.com/appengine).\n The region appears near the top of the page.\n\nTo select a region, you create an App Engine application in your\nGoogle Cloud project.
