Techniques for managing and using telecommunication carrier deactivation lists

Abstract:

Techniques are described for managing the recipients of application-to-person (A2P) short message service (SMS) messages. A send-to list comprised of telephone numbers to which to send A2P short message service (SMS) messages is received from an A2P sender. The opt-in/opt-out status of each telephone number on the send-to list is determined. Telephone numbers on the send-to list that cannot be verified as opt-in status are flagged as opt-out status. The A2P sender is then prevented from sending of A2P SMS messages to telephone numbers flagged as opt-out status.
