# Incoming Phone Number Assigned Add-ons Subresource

This endpoint allows Add-on Listing users to see the installed Add-on Listings assigned to a given Twilio phone number. It also allows users to assign and unassign an installed Add-on Listing to an incoming phone number.

Add-on Listings assigned to a specific Twilio phone number are used only for calls and messages associated with that phone number rather than the entire Twilio account.

Add-on Listings enabled for Recordings and TaskRouter don't support phone number assignments.

> \[!NOTE]
>
> This API only supports Add-on Listings that are in General Availability (GA) or Beta state. Listings that are labeled as Coming Soon or Developer Preview are not accessible via the API and must be managed in the Console.
