Short Codes

U.S. and Canadian short codes are the single source for bulk delivery of marketing campaigns in North America.

“Our focus is consumer-centric mobile communication, supporting multiple use cases. We migrated our messaging to Aerialink's Cloud Communications Platform because they have a best of breed technology that we can rely on, and the API supports messaging over toll free numbers, short codes and long codes.”

Mark Highbaugh Sr.
