The PhoneID Number Deactivation API determines whether a phone number has been deactivated, when, and by which carrier the phone number was deactivated based on carriers' phone number data and TeleSign's proprietary analysis. NOTE: If you try this API out using the API Explorer, you will be billed for the transaction as you normally would.
