4 mins

Introduction to 10DLC and A2P Messaging

The landscape of business texting in the United States is evolving with the implementation of 10 Digital Long Codes (10DLC) and Application-to-Person (A2P) messaging. This blog aims to demystify the seemingly complicated 10DLC and A2P messaging, explaining their significance and the process of utilizing online SMS services effectively.


What are 10 Digital Long Codes (10DLC)?

10DLCs are standard 10-digit phone numbers designed specifically for SMS business messaging.  

They offer a cost-effective and efficient way for businesses to send Application-to-Person (A2P) SMS messages. Unlike short codes, 10DLCs provide a more traditional phone number format while still supporting high-volume messaging needs once registered with The Campaign Registry (TCR).  

Notifyre offers users 10DLC numbers and the ability to register 10DLC with the TCR for high-volume SMS sending. 


The Role of A2P Messaging in Business SMS Communication

A2P messaging refers to SMS messages sent from an application to a person, predominantly used by businesses for various communication touch points in their customer journey such as notifications, marketing messages, or customer service interactions.  

With the rise of A2P messaging, carriers in the US have started offering better delivery quality and lower filtering risk for messages sent via 10DLCs. To access these benefits business can register 10DLCs.

Understanding The Campaign Registry

The Campaign Registry plays a crucial role in the A2P 10DLC ecosystem. It performs company identification checks and reviews SMS campaign data, ensuring transparency for Mobile Network Operators (MNOs) in the US. This process helps to increase throughput rates and reduce spam and fraud in SMS messaging. It is recommended that all 10DLCs are registered with the TCR to access high-volume sending.  

Businesses can register with an online SMS service like Notifyre, which provides users with the ability to register their Brand and SMS campaign with the TCR.

Best Practices for SMS Content for 10DLC Campaigns

  • Consistent Use of Numbers: Use one recognizable number for each campaign.
  • Web Domain Consistency in URLs: Ensure the use of a consistent web domain in URLs.
  • Clarity and Professionalism in Language: Use natural language and avoid textspeak.
  • Business Identification: Include your business name in the SMS for instant recognition.
  • Message Length and Clarity: Keep SMS messages concise and clear, preferably within 160 characters.
  • Opt-Out and Help Options: Always include "STOP" and "HELP" instructions in your SMS. An unsubscribe method must always be visible in the SMS message.

Navigating A2P 10DLC Registration Requirements

A2P 10DLC registration is recommended for sending SMS messages to US phone numbers. Unregistered 10DLC numbers will face message restrictions and messages can be blocked by carriers. To comply, register your 10DLC with an approved CPS, such as Notifyre.

Failing to register a A2P 10DLC can lead to increased message filtering and blocking. It's crucial to understand and adhere to these requirements to avoid disruptions in your text messaging services.
