Dedicated Short Codes

Recently, the major U.S. carriers have announced new restrictions for sending SMS in the U.S. U.S. carriers plan to deprecate shared short codes. A shared short code is a 5-6 digit number managed by Telesign which carries traffic from multiple customers. Carriers are now requiring each brand to obtain their own dedicated senderID, meaning a shared short code managed by Telesign will no longer be possible. Therefore, all existing shared short codes are now required to register as one of the following:

To help ensure continuous delivery of SMS, please begin the Dedicated Short Code registration process by completing the “DSC Registration” form at the button above. Once the completed form is received, our teams will begin the registration process with the operators on your behalf. The registration time may vary depending on the campaign.

For more information you can read the “10DLC QA” or see the comparison chart below. We greatly appreciate your cooperation and assistance throughout this process.
