What is A2P 10DLC?
A2P 10DLC is the US carrier framework for sending application-to-person (A2P) text messages from a standard 10-digit long code (10DLC), which requires registering your brand and message campaigns to send at scale.
Compliant SMS, without the registration burden.
VanceTel sends from dedicated business numbers registered for A2P 10DLC, and manages the brand and campaign plumbing behind them. STOP, START and HELP are intercepted automatically for TCPA opt-out compliance, so a message to an opted-out number is rejected before it sends.
A2P 10DLC in practice.
A clinic wants to text appointment reminders from its local number. Because those texts are sent by software, carriers treat them as A2P and expect a registered 10DLC campaign. With VanceTel, the clinic sends through a number already registered for A2P 10DLC, so reminders are delivered as compliant business traffic rather than filtered out.

What does A2P 10DLC stand for?
A2P means application-to-person — messages your software sends to people, as opposed to person-to-person texting. 10DLC means a 10-digit long code, the ordinary local phone number format. Together, A2P 10DLC is the registered, carrier-sanctioned way to send business SMS from a standard local number in the US.
Do I need A2P 10DLC registration to send business SMS?
In the US, yes. Carriers require brands and campaigns to be registered for A2P 10DLC traffic; unregistered application traffic gets filtered or blocked. VanceTel sends from dedicated business numbers registered for A2P 10DLC, so your messages are carrier-compliant.
Does VanceTel handle the A2P 10DLC plumbing?
Yes. VanceTel manages the brand and campaign registration behind your numbers, and intercepts STOP, START and HELP for opt-out compliance automatically. You call one REST endpoint to send, and the compliance layer is part of the platform rather than something you build.
