10DLC - What is it?
10DLC stands for 10-digit Long Code. 10DLC messaging lets businesses send sanctioned Application-to-Person (A2P) messaging traffic over local phone numbers, also known as “long codes”.
What is a Brand?
The company or entity the End Customer believes to be sending the message.
What is a Campaign?
A “Campaign” is simply the use case of your messaging and defines the type of content
you will be sending. For example, if you use SMS for marketing purposes, you would
register a Marketing campaign. If you use SMS for 2-way customer support, you would
register a “Customer Care” campaign. There are many campaign types to choose from,
and brands should speak to their CSP to ensure the correct campaign type is used.
Why do I have to register my Brand and Campaign?
The industry has been working for many years to find ways to support the use of local numbers to deliver A2P messaging traffic to mobile subscribers at volume. Following the recognition by the CTIA in 2019 that local and toll-free numbers are valid methods for delivering A2P traffic, mobile carriers have been developing their 10DLC solutions.
Verizon charges a blanket surcharge on top of messages without additional registration, while AT&T and T-Mobile do require registration and additional fees to increase throughput caps for campaigns that should be granted a higher messaging class. They also require the use of TCR to get additional information on A2P message senders and the type of traffic being sent to their mobile subscribers.
