What is 10DLC (A2P Messaging)?
10DLC (10-Digit Long Code) is the standard in the United States that allows businesses to send SMS messages using local phone numbers in a registered and carrier-approved way.
All business messaging must be registered through The Campaign Registry (TCR) to ensure compliance and proper delivery.
Important: Unregistered messaging is subject to blocking, filtering, or complete delivery failure.
