A2P 10DLC: Everything You Need To Know

Businesses today are constantly seeking new ways to connect with their customers, and one powerful tool in their arsenal is business texting. However, if you have looked into business texting for your business, and found yourself puzzled by terms like A2P 10DLC, you’re not alone. In this post, we’ll explain A2P 10DLC and shed light on what it is and why it matters for your business. 

The When of A2P 10DLC

As of early 2021, major carriers have made 10DLC registration mandatory. This enforcement underscores the importance of A2P 10DLC compliance, especially as landline texting continues to gain popularity. To continue texting your customers without disruptions, it’s crucial to ensure your business is registered and compliant with all regulations. 

The What of A2P 10DLC

A2P stands for Application to Person 10-digit Long Code.  Your “10-digit long code” being your landline textphone number (area code + telephone number).  And your “application to person” being your business texting with another person or customer. 

If your business engages in texting with customers, registering for A2P 10DLC is essential. It not only identifies your business but also validates your authenticity when sending texts from your landline. But why does proving your authenticity matter? 

To combat illegal robo-texting and spam, major telephone carriers such as AT&T and T-Mobile have embraced A2P 10DLC. To become compliant, businesses must go through a registration process, managed by The Campaign Registry (“TCR”). In short, the registration process verifies your business and landline number and ensures you’re not intending to use text in an illegal or deceitful way. 

The Campaign Registry, a third-party service provider, collaborates with North American mobile operators and landline texting providers, like TextBetter, to validate and monitor participants. TCR registration ensures deliverability, creates a higher messaging output and is the industry standard in terms of compliance. 

The Why of A2P 10DLC

So, why is A2P 10DLC essential for businesses? It serves a dual purpose: offering businesses a reliable and secure communication channel while protecting consumers from unsolicited messages. 

  • Building Trust: A2P 10DLC messaging is highly vetted. When a company meets the requirements, mobile carriers like T-Mobile and Verizon recognize the brand, phone number, and message. This recognition ensures your SMS messages bypass spam filters and reach your customers’ mobile phones. 
  • Enhanced Security: By requiring businesses to register and authenticate themselves, it becomes much more challenging for spammers and scammers to use these channels for fraudulent activities. This ultimately makes the messaging ecosystem safer for everyone involved.
