# UpdatePhoneNumber
Updates your claimed phone number from its current Amazon Connect instance or traffic distribution group to another Amazon Connect instance or traffic distribution group in the same AWS Region.
**Important**
After using this API, you must verify that the phone number is attached to the correct flow in the target instance or traffic distribution group. You need to do this because the API switches only the phone number to a new instance or traffic distribution group. It doesn't migrate the flow configuration of the phone number, too.
You can call [DescribePhoneNumber](https://docs.aws.amazon.com/connect/latest/APIReference/API_DescribePhoneNumber.html) API to verify the status of a previous [UpdatePhoneNumber](https://docs.aws.amazon.com/connect/latest/APIReference/API_UpdatePhoneNumber.html) operation.
