A2P 10DLC: business texting on local numbers
10DLC means sending application-to-person messages from ordinary 10-digit long code numbers. Before the first message goes out, mobile carriers need to know who is sending and what they send.

Why 10DLC
Register the sender, then each kind of message
Every message sent through CarrierX's messaging API counts as application-to-person (A2P). To combat spam and fraud, mobile carriers require your use case to be registered and approved before you send.
Numbers that look local
Long codes are numbers people think of as local, and several can be pooled so each is local to the people you text.
Low cost, low barrier
Long codes are the most popular number type for business messaging, thanks to their low cost and low barrier to entry.
One review, not many
10DLC registration is reviewed by a single body rather than by each carrier, which keeps the process simpler.
Before you register
What carriers look for
These requirements apply whichever number type you choose. Having them in place before you apply keeps the review moving.
Clear opt-in
Recipients must agree before they receive messages. The opt-in names your brand and the types of messages, states frequency and that message and data rates may apply, and links to your terms and privacy policy.
STOP and HELP
Your application must stop messaging anyone who replies STOP, and answer HELP with your brand name, a support contact and how to opt out.
Sample messages
Carriers review examples of what you will send, one for each type of message in the campaign.
Terms and privacy
Both are linked from the opt-in. The privacy policy has to say that messaging opt-in data is not shared with third parties.
A consistent identity
Your company name should match your email and website domains, and the registration should include a support phone number and email address.
