10 Digit Long Code (10DLC) SMS rules and what you need to know.

In June of 2021, all enterprise-level long code SMS and MMS messages that are sent through to multiple Major U.S carriers are being moved to a new 10-digit long code (10 DLC) Application-to-Person service. This service will be used to outline new content procedures and categorization for mass SMS services moving forward.

Please note, this applies to US Carriers only and does not apply to Canadian traffic on Canadian Carriers.

What is 10DLC?

10DLC allows for a higher messaging quantity per long code and deliverability than more traditional long code bulk messaging types. A 10DLC number is a local 10-digit phone number and has the benefits for

There will be registration requirements for 10DLC sender numbers, implemented to protect recipients from unwanted spam, while also improving deliverability. 10DLC requires SMS Providers to register the businesses that use their SMS Long code lines and well as categorize them into use case groupings. Each of these groupings will then be assigned a ‘trust score’ which can affect the amount of throughput a group can use. The end goal of these measures is increasing transparency regarding who is sending large amounts of SMS and what they are sending.

10DLC is designed to be an alternative option to shared short code numbers, which present a significantly higher risk of being used to send spam. It is also a more affordable option than dedicated short codes.

What will I have to do?

If you are a Canadian client sending to Canadian customers, there is nothing you need to do. If you are a US client sending to US based clients, then Odyssey will advise of the required steps. Odyssey is in the process of organizing the required groupings and will send out further information to customers when it becomes available and relevant.
