Enhance your current messaging setup with 10DLC

10DLC is meant to replace shared short codes and unvetted long codes. If you’re using dedicated short codes, you’re good. However, you might want to complement your set up with localized campaigns enabling personalized two-way conversations over SMS, MMS and voice calls, all in one solution. 

Higher throughput

Whether you need to send a few messages a day or millions of them, you can choose from a wide range of throughput levels to suit your needs, use case, and vetting score.


Build trust and increase open rates with local, recognizable phone numbers. You can even get specific area codes! 

SMS, MMS, and voice calls

Need more than text messaging? No problem - 10DLC numbers support MMS and voice calls. 

Compatible with landlines

Businesses can provision their landlines as 10DLC and use existing numbers for sending and receiving SMS. 

Two-way conversations

10DLC messaging enables more personalized, two-way business messaging so you can engage with more customers! 

Number anonymization

Mask phone numbers to protect your business and your users’ private numbers - keeping conversations on your platform. 


When people can’t trust that callers are who they claim to be, they stop answering even legitimate calls. Caller ID authentication ensures that customers feel confident saying hello rather than dismissing a call.

Have questions?

  • What is 10-digit long code (10DLC)?

    10-Digit Long Code is a new conversational messaging solution that offers better visibility, engagement and cost-efficiency and adds trust to the customer relationship. 10DLC allows brands to send local A2P text messages using 10-digit local numbers available in the North American Numbering Plan (NANP). 

  • What is the difference between P2P and A2P messaging?

    Application-to-Person (A2P) messages are typically generated via a software application. Used by businesses to engage with customers, they're often called "transactional" as they're used for notifications, alerts, appointment reminders, etc. Person-to-Person (P2P) messaging refers to a conversation or dialogue between two individuals. P2P has low volumes and lower throughput.

  • What's a vetting score and how does it affect campaigns?

    The 10DLC registration process gives you the opportunity to have your brand vetted, which allows you to get a higher message throughput. Along with your use case, this will help carriers determine your total messaging throughput.

  • What are the best use cases for A2P 10DLC messaging?

    10DLC is ideal for A2P transactional messages such as appointment reminders, one-time pin codes, service updates, alerts, and smaller marketing campaigns.

  • Is 10DLC right for me?

    Short codes will still be beneficial to most brands. However, if you're sharing a short code for U.S. traffic or have been using long codes that aren't registered and vetted by carriers, you’ll need to move your traffic to a registered, sanctioned A2P messaging solution - 10DLC!

    10DLC numbers are a great alternative to your non-sanctioned long numbers and shared short codes, providing a low-cost, sanctioned messaging channel for business messaging.

  • Can I use short codes and 10DLC together?

    10DLC is a great complement to short codes if you want to run national A2P campaigns and need high speed, high throughput, and personalized two-way conversations to engage your audience on their own terms via voice, chatbot, video, or MMS services - all in one solution!
