Genesys Cloud support of 10DLC (10-Digit Long Code)

The US Mobile Network Operators (MNOs) has established a new program called 10DLC (10-Digit Long Code) to classify A2P (Application-to-Person) text messaging and create a formal process for allowing 10-Digit phone numbers to be used to send and receive text messages. The goal of the 10DLC program is to decrease text spam and phishing messages originating from 10DLC senders. To make this possible, there is now a central registration system which is used to evaluate and legitimize 10DLC messaging.

Genesys is implementing plans internally to create a process for our SMS Long Code customers to register and to be compliant  the 10DLC program. We will update this article with more specific details in the coming weeks. Any changes or additions to this article will be documented in the Revision history section at the bottom of this page. Please bookmark this page so you can easily stay abreast of any changes. 

What is A2P Text Messaging?

The MNOs classify A2P text messaging as any business-to-consumer SMS that routes to or from software regardless of the use case. This means any SMS sent from or received by Genesys software is classified as A2P.

What is 10DLC?

10DLC, short for 10-Digit Long Code, is the MNOs’ product name for their new A2P messaging service when using standard U.S. phone numbers; for example, 16175551212.

Using a 10DLC for SMS was so easy to get up and running. Why change that?

That is the very reason why the MNOs are launching 10DLC. Unlike with Short Codes, there is no formal process to text-enable a phone number and, with the good comes the bad. Wireless subscribers have seen a significant increase in text spam and phishing messages originating from 10DLC senders. The new product offering establishes the controls to reduce the number of unsolicited texts to wireless subscribers.

What enhancements does 10DLC offer?

10DLC is viewed by the MNO’s as a Short Code alternative. It includes a new central registration system which is used to evaluate and legitimize the messaging in addition to greater support for higher volume messaging programs.

What do I need to do to register?

Registration will consist of registering your company and the campaigns (use cases) you plan to use with your 10DLC’s. Genesys will gather the registration information and will register the 10DLC program on your behalf. Registration will consist of four main pieces of information:

  • Your company information – name, address, etc.
  • Your intended use case for 10DLC messaging – notifications, marketing, etc.
  • On how your company is obtaining consent to text with your customers.
  • What 10DLC phone numbers are associated with the program.

For more information, see Download the 10DLC registration form.

If you are a Charity or Political Organization, please reach out to for specific registration requirements.

When do I need to register by?

Each MNO had different timelines for implementation of registration requirements. A formal timeline of October 2021 has been provided by MNO’s for registration.

What happens if I don’t register?

Unregistered 10DLC’s may be subject to blocking and throughput limitations. To ensure messages sent by your business are received, your 10DLC’s will need to be registered. If you no longer want to use your 10DLC numbers due to this change, please release them from Genesys Cloud in the SMS Inventory and no further charges will be incurred. You might also consider using a different number type such as a Toll-Free number or a Short Code.

Is the registration requirement the only change?

No! The MNOs are using the registration system to evaluate the use case to determine how many SMS per day they will permit and how they will surcharge the messaging. MNOs are adding new monitoring systems that will manage throughput versus daily allotments and ensure message content is in line with best practices.

Are the MNOs really going to limit the amount of SMS I can send customers every day?
Yes, one of the overarching drivers behind this launch is to protect the networks and subscribers from a flood of messages. The limits of messages allowed per day differs per MNO so it depends on which MNO your subscribers are using and which subscribers you send messages to each day.

How will I know if I’ve reached my daily limits?

Genesys will help manage this on your behalf through rate limiting controls built into the platform.

What surcharges are being assessed and will my rates change?

Each MNO is taking a different approach to how they implement surcharges, but all are implementing new per message fees that vary based on use case, direction, and other contributing factors. Brand and Campaign registration activities will also assess new fees. Genesys will be passing-through Registration and Recurring fees at no markup. Per message fees being charged by the US Wireless Carriers will be covered by our current per message pricing with no changes.

Latest pricing information can be found the Messaging pricing article. New Genesys pricing for 10DLC MNO surcharges will be effective November 1st, 2021.

Do these changes only apply to SMS or is MMS affected to0?

MMS is affected as well. Throughput and surcharges for MMS will vary by use case.

Will these changes apply to toll-free numbers as well?

Yes, there is a similar registration requirement for toll-free A2P messaging. For more information, see Genesys Cloud support of toll-free messaging verification for the United States and Canada.

Is voice on 10DLC impacted by this change?

No, there is no impact to voice traffic on US 10DLC’s.

What about existing 10DLC numbers I already own and use today? Do I need to register those?

Yes. If you are already using 10DLC’s for SMS, you will need to complete Brand and Campaign registration and associate your 10DLC’s with the appropriate campaign.
