# List traffic distribution groups
List traffic distribution groups

Use the [ListTrafficDistributionGroups](https://docs.aws.amazon.com/connect/latest/APIReference/API_ListTrafficDistributionGroups.html) API to list all traffic distribution groups.

You may want to list traffic distribution groups as a way of determining whether a particular Amazon Connect instance is part of any traffic distribution groups.

# Delete traffic distribution groups in Amazon Connect
Delete traffic distribution groups

Use the [DeleteTrafficDistributionGroup](https://docs.aws.amazon.com/connect/latest/APIReference/API_DeleteTrafficDistributionGroup.html) API to delete a traffic distribution group that is no longer needed.

**Note**  
You cannot delete a traffic distribution group if phone numbers are claimed to it. You must first release phone numbers from the traffic distribution group by using the [ReleasePhoneNumber](https://docs.aws.amazon.com/connect/latest/APIReference/API_ReleasePhoneNumber.html) API. After that, you can delete the traffic distribution group.  
You cannot release numbers from a traffic distribution group by using the Amazon Connect console. 

Your [DeleteTrafficDistributionGroup](https://docs.aws.amazon.com/connect/latest/APIReference/API_DeleteTrafficDistributionGroup.html) API call will fail with an `ResourceInUseException` if phone numbers are still claimed to the traffic distribution group.
