A2P 10DLC is a mandatory registration system for businesses that send SMS messages in the U.S.
A 10DLC allows companies to send Application-to-Person (A2P) SMS messages using a standard 10-digit phone number (10DLC), while improving deliverability, reducing spam, and ensuring compliance with carrier regulations.
If your business relies on SMS to communicate with leads or customers, A2P 10DLC is essential to ensure your messages are delivered reliably and not blocked by carriers.
What is A2P 10DLC?
A2P 10DLC is a U.S. system that enables businesses to send Application-to-Person (A2P) messages using standard 10-digit phone numbers.
Initially, long code messaging was designed for person-to-person (P2P) communication between individuals, like family and friends.
With A2P 10DLC, businesses can now use standard 10-digit numbers to send higher volumes of messages to customers in a more reliable and secure way, while helping reduce spam and protect consumers.
How Does A2P 10 DLC Registration Work?
To start sending A2P messages, you need to complete two key steps:
- Brand Registration
You must register your business and verify your identity with carriers.
This includes submitting:
- Business name and address
- Business type and details
- Company identity information, including EIN.
- Campaign Registration
After your brand is approved, you need to register your messaging campaign.
This includes:
- Defining your use case (e.g., promotions, alerts, 2FA)
- Receiving a trust score from The Campaign Registry (TCR)
- Determining your messaging throughput based on your score and campaign type
Although this process may seem difficult, it’s not. Smarter Contact is happy to guide our customers and help when needed.
