What is 10DLC?

10 DLC  stands for 10 Digit Long Code.   It is the new standard for A2P messaging in the USA, which applies to all messaging over 10 digit geographic phone numbers.

 

What Are The New SMS A2P Messaging Changes?

Major US carriers have announced their requirements for SMS A2P (application to person) messaging using 10 digit geographic numbers, also known as 10 DLC. This new standard provides many benefits to our customers including supporting higher messaging speeds and better deliverability.

 

Timeline

Each US carrier is implementing 10DLC over different time periods, and Vonage is working with each carrier to make sure our customers meet all requirements and timelines. 

  • Verizon launched with 10DLC in early 2020 and pass-through fees can be viewed here.
  • AT&T has soft-launched with 10 DLC, and pass-through fees are expected in early 2021.
  • T-Mobile and Sprint have soft-launched with 10 DLC, and pass-through fees are expected to be charged beginning March 1,  2021.  
  • You can get the latest information on each US Carrier’s 10 DLC launch status here.

 

Requirements

  • Customers using the Vonage SMS API to send traffic from a +1 Country Code 10-Digit Long Code into US networks will need to register a brand and campaign in order to get approval for sending messages.  
    • This guide will help you classify your use case campaigns and make sure they are approved for 10DLC ahead of your transition.
    • Customers can only send messages with the same use case that have been registered with their campaign
  • Resellers of Vonage SMS services will, in most cases, need to register their customers' brands and campaigns for them.
  • US numbers can no longer be shared across brands which includes both geographic numbers and US Shared Short Codes

Pricing:  

Pricing is being finalized and we will share pricing models once they have been confirmed. 10DLC pass through fees per carrier will be updated on this page.

 

*See below “Migration Options” section for more details.

 

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 will no longer be 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
  • 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.

Migrating to Dedicated Short Codes

If you are sending SMS traffic that requires higher than 50 messages per second in throughput, and/or are sending high message volumes of more than 500,000 messages per month, we recommend you migrate to a Dedicated Short Code.

Using a Dedicated Short Code comes at a higher cost than 10DLC, but it is the most reliable option for high volumes of SMS traffic and delivering at high throughput speeds.

 

Migrating to Toll Free Numbers

If you are sending SMS traffic that requires a throughput of up to 30 messages per second, and/or are sending medium to high volumes of up to 500,000 messages per month, you may utilize a Toll Free Number for your A2P traffic.

Bear in mind that if your campaign involves marketing or promotional content, using a Toll Free Number is not suggested since the traffic will likely be blocked by spam filters.  Toll free Numbers should only be used for Non-Marketing, Customer Service, and Alert Notifications use cases.  

As a best practice, all marketing or promotional campaigns should be sent over a dedicated short code or via a 10DLC once available, and opt-in/opt-out protocols must be met.  More info on best practices can be found here.

 

Migrating to 10DLC 

 

Who should migrate to 10DLC?

If you are sending SMS traffic that requires no more than 50 messages per second in throughput, and/or are sending less than 200,000 messages per day, we recommend you migrate to 10DLC.  Note if you already use a Vonage 10 digit long code number for outbound SMS to the US you will need to register a brand and campaign to conform with the new SMS A2P 10DLC guidelines.

 

What do I need to do to prepare for 10DLC? 

If you choose to use 10DLC for A2P messaging, you will need to register your brand and a campaign with use case details. This Use Case Campaign guide will help you classify your use case campaigns and make sure they are approved for 10DLC, ahead of your transition.  The guide will help you determine if you can and should use 10DLC or if you should work with your Vonage Account Manager to find a more fitting solution. 

 

10DLC Transition Preparation Items:

  1. Map your use cases to one of the pre-defined use case campaign descriptions. 
  2. Determine your required throughput for each use case.  See above chart for guidance. 
  3. Once available, Register your brand and campaign information with Vonage.

 

Vonage Application Partners Preparation:

Application Partners sell enterprise SaaS platforms embedded with our Vonage SMS API.

  1. Map  your use cases to one of the pre-defined use case campaign descriptions. 
  2. Determine your required throughput for each use case.  See above “Migration Options” chart for guidance. 
  3. You can register one brand and one campaign per use case.  A unique campaign ID will be associated with this campaign. 
  4. You can associate all relevant customers’ numbers to that unique campaign ID, given it is part of the same use case. 

 

Vonage SMS Reseller Preparation:

Vonage SMS Resellers are those who resell the Vonage SMS API.

  1. Map your use cases to one of the pre-defined use case campaign descriptions. 
  2. Determine your customer’s required throughput for each use case.  See above chart for guidance. 
  3. You must register each of your customer’s brand and campaign information.
