**Note**  
**New user?** Check out the [Connect Customer Global Resiliency Workshop](https://catalog.workshops.aws/amazon-connect-global-resiliency/en-US). This online course guides you through the process of onboarding and testing phone number and agent failover using new APIs through the AWS CLI.  
Global Resiliency is available only for Connect Customer instances created in the following AWS Regions: US East (N. Virginia), US West (Oregon), Asia Pacific (Osaka), Asia Pacific (Tokyo), Europe (Frankfurt), and Europe (London).  
You can only create a replica in the US East (N. Virginia) Region if your source is US West (Oregon), or the other way around. 
You can only create a replica in the Europe (Frankfurt) Region if your source is Europe (London), or the other way around.
You can only create a replica in Asia Pacific (Osaka) Region if your source is Asia Pacific (Tokyo).
To obtain access to this feature, contact your Connect Customer Solutions Architect or Technical Account Manager.

You can move a phone number that was previously claimed to an instance, and instead assign it to multiple instances across AWS Regions. You do this by assigning the phone number to a traffic distribution group.

**To assign a phone number to a traffic distribution group**

1. Create a traffic distribution group using the [CreateTrafficDistributionGroup](https://docs.aws.amazon.com/connect/latest/APIReference/API_CreateTrafficDistributionGroup.html) API.

1.  Describe your traffic distribution group using the [DescribeTrafficDistributionGroup](https://docs.aws.amazon.com/connect/latest/APIReference/API_DescribeTrafficDistributionGroup.html) API to determine whether it has been created successfully (`Status` must be `ACTIVE`).

1. After your traffic distribution group is created successfully (`Status` is `ACTIVE`), you can assign phone numbers that were previously claimed to other instances or other traffic distribution groups. Use the [UpdatePhoneNumber](https://docs.aws.amazon.com/connect/latest/APIReference/API_UpdatePhoneNumber.html) API.
