Viral messaging (short code only)
Last updated: April 2025
Viral messaging is a process in which a consumer receives a message, identifies one or more other consumers as likely to be interested in receiving a similar message, and then initiates a process for the other consumers to receive the message. For example, consumer A may input consumer B's phone number into an app to send a message to consumer B through short code.
Messaging channel | Allowed requirements |
---|---|
Short code | A message sender may send viral messaging through short code. The mechanism for a message sender to send viral messaging requires a consumer to:
Message senders must honor all opt-out requests from message recipients by opting the message recipient out of all messages sent through the viral messaging application, software, or program. Additionally, consumers sending viral messaging may not receive anything of value for using the viral messaging application, software, or program. To be consistent with the CTIA Short Code Monitoring Handbook's goals, these requirements honor consumer choice, help prevent abuse of messaging platforms, and facilitate transparency. |
