Texting via landline or VoIP numbers has grown increasingly popular over the last several years. Mobile carriers want to ensure texting stays a channel of communication that consumers can trust, that’s free of SPAM and unsolicited messages. To do this, they’ve created 10DLC.
So what is 10DLC and why does it matter?
10DLC is short for 10 digit-long-code, which is a channel created by carriers for business to consumer messaging over local landline numbers. Carriers have worked together to adopt a set of standards and registration processes to better understand who is using 10DLC and what they’re sending across the network.
What does this mean for my business?
All businesses that are taking advantage of text messaging using a A2P (application to person) carrier with a local phone number are required by U.S. mobile carriers to register with a chosen third-party partner. Businesses are then vetted and given a “trust score” that determines their daily message throughput. In addition to protecting consumers, controlling message quotas in this way allows the carriers to increase message speed and offer businesses better deliverability. By not registering and continuing to use a 10DLC phone number to send text messages, the business will eventually experience disruption of service. Certain carriers will stop supporting SMS traffic from 10DLC numbers that are unregistered, meaning messages to customers on that carrier will fail and the sender will receive an error message.
