Navigating A2P 10DLC registration with Twilio for TopView SMS notifications
Twilio's A2P 10DLC registration is to comply with carrier requirements
This registration is enforced by carriers and meant to prevent spam.
Carriers consider all SMS traffic from Twilio to be sent from an application, so anyone using a 10DLC number with Twilio to send SMS messages to the US will need to register. This includes individuals and hobbyists using Twilio.
Ten-digit long code numbers in the US were originally designed for person to person (P2P) communication. These routes were unregulated, and in recent years have started seeing abuse from spam applications and unsolicited messaging.
Due to the increase in spam messages, many consumers have lost trust in SMS as a form of communication. US A2P 10DLC is the standard that carriers have implemented in the US to regulate this communication pathway.
Registration tips
Brand Type: Most small U.S.
organizations qualify as “Low Volume Standard Brand”
EIN required, less
than 6,000 msg/day
Skips expensive
secondary vetting, much simpler!
"Sole Proprietorship" registrations likely will fail if Twilio is given a company email address
Campaign Use Case: Use the
“Account Notification” campaign type for alarm/alerting. For
municipal/government, “Emergency” may also be appropriate.
Templates/Samples:
Clearly label the
customer/brand (“City Water Plant”) in sample messages
Every sample must
include opt-out language, even if it feels odd (“Alert: Water Pump #2
Alarm. Reply STOP to end alerts.”)
Provide 2 specific
sample messages (not just “test”, “notification”)
