Why is my Sender ID not Delivering?

Each destination has its own particular rules and regulations regarding what type of Sender ID can be used. Restrictions are put in place by Carriers and can result in some message SenderIDs being overwritten or failing. In some destinations SenderIDs also need to be pre-registered so be accepted by the carrier.

If you are experiencing any issues with SenderIDs please contact your Account Manager. We monitor network restrictions and can assist you with ensuring your messages are delivered. You can also find out more country specific information in our Global SMS Features & Restrictions Almanac.
