Question

What is 10DLC Messaging? What is going to change with A2P 10DLC messaging?

Applies To

• US Numbers
• US Carriers
• SMS
• 10 Digit Long Code (10DLC)
• Shared Short Codes
• App-to-Person (A2P)

Answer

10DLC

10DLC stands for 10 Digit Long Code. It is the new standard for A2P messaging in the US, which applies to all messaging over 10 digit geographic phone numbers. Major US carriers have announced their requirements for SMS A2P (application-to-person) messaging using 10 digit geographic numbers, also known as 10DLC. This new standard provides many benefits to our users including supporting higher messaging speeds and better deliverability.

Background on long codes (long virtual numbers)

Long codes (aka Long Virtual Numbers, LVNs, or long numbers) are essentially 10 digit phone numbers designated by the mobile operators for person-to-person communication. Some sample use cases include chat applications, anonymous dating applications, and customer service communications.

Historically in the United States, P2P (person-to-person) traffic (not A2P traffic) is permissible using a Vonage USA long code or LVN. Long virtual numbers are available here if your business does not already own one. There are also additional use case limitations for long code traffic, which can be viewed in more detail here.

What is A2P 10DLC?

10DLC, which stands for 10 Digit Long Code, is the new standard for A2P messaging in the US, which applies to all messaging over 10 digit geographic phone numbers. They are also the fixed numbers you may bring over to Vonage for SMS provisioning. A 10DLC number is essentially a local 10-digit phone number that can support higher volumes of text messages. Many experts anticipate that 10DLC will become the new standard for business text messaging. 10DLC numbers are designed and sanctioned by the termination vendors for A2P SMS messaging.

How is A2P 10DLC changing the rules in short and long code use?

Since A2P (application-to-person) traffic on long codes historically has not been supported by the carriers, businesses have been forced to utilise short codes for their A2P needs. However, for carriers that are opting to launch and support A2P for 10DLC in the USA, this limitation will be lifted and A2P traffic will be allowed (with new guidelines).

Important Notice to Vonage Customers Using US Shared Short Codes

T-Mobile and AT&T’s new Code of Conduct prohibits the use of shared originators, therefore, Shared Short codes are not an acceptable format for A2P messaging.

Vonage customers using a Shared Short Code, must migrate SMS traffic to either a 10DLC, Toll Free SMS Number, or Dedicated Short Code before March 1, 2022.

Vonage customers using our Shared Short Code API must migrate to either our SMS API or Verify API.

Customers using Dedicated Short Codes are not affected by these changes within the scope of 10DLC.

Vonage has leveraged this new offering and is live with Verizon’s enhanced commercial text messaging platform. The following Verizon pass-through fee will be added to mobile terminated (MT) messages originating from long codes:
