What is US A2P 10DLC registration asks for a definition with the country included. It is the The Campaign Registry (TCR) brand-and-campaign event that covers Application-to-Person (A2P) SMS leaving a United States 10-Digit Long Code (10DLC) toward US mobile subscribers.
Definition Pieces
US names the carrier framework. A2P names software-originated traffic. 10DLC names the local from-number. Registration names the two TCR records that bind those pieces.
A non-US company sending on that path still completes this definition when identity checks pass. A US company sending only inside Canada does not.
What the Definition Leaves Out
Toll-free verification. Short-code applications. Person-to-person consumer threads. Federal Communications Commission (FCC) licenses. Those items have other names.
FAQ
What is US A2P 10DLC registration required to prove?
