# Enabling or disabling opt-in Regions in AWS User Notifications
Enabling or disabling opt-in Regions

Although most AWS Regions are active by default for your AWS account, certain Regions are activated only when you manually select them. This document refers to those Regions as *opt-in Regions*. In contrast, Regions that are active by default, as soon as your AWS account is created, are referred to as *commercial Regions*, or simply, *Regions*.

If you choose to select an opt-in Region as your notification hub, enable it first by following the steps in [Enabling a Region](https://docs.aws.amazon.com//general/latest/gr/rande-manage.html#rande-manage-enable). Enabling or disabling an opt-in Region may impact your notifications experience. For a list of supported opt-in Regions, see [Opt-in Regions](supported-regions.md#opt-in-Regions).

## Disabling a notification hub Region


You must have a notification hub configured to create notification configurations. If you disable an opt-in Region that contains your only notification hub, you can't create new notification configurations. You also can't access previous notifications until you enable the opt-in Region or create a new notification hub.

### Choosing a notification hub Region that isn't enabled


You must enable an opt-in Region to use a notification hub you create in that opt-in Region. If you don't enable the opt-in Region, your notification hub remains inactive. You can't create notification configurations or view notifications until you enable that opt-in Region on your account or select a new notification hub.
