Any text message transmitted via our platforms, regardless of the use case or phone number type (e.g., long code, short code, or toll-free), will be considered by The Campaign Registry (TCR) to be an Application-to-Person (A2P) messaging.

Per The Campaign Registry (TCR) rules, Application-to-Person (A2P) SMS and MMS message traffic may not be delivered to US-based end-user mobile devices unless the message traffic is properly registered as a campaign.
