What is A2P 10DLC?
A2P 10DLC (Application-to-Person 10-Digit Long Code) is the regulatory framework established by US mobile carriers (AT&T, T-Mobile, and Verizon) to eliminate spam, phishing, and unverified commercial messaging over standard local phone numbers.
If your business transmits automated appointment reminders, customer receipts, or transactional notifications, compliance with 10DLC registration standards is essential to prevent carrier message blocking.
