Telnyx Number Verification
What is 10DLC Verification?
A2P (Application to Person) 10DLC (10 digit long code) is the standard that United States telecom carriers have put in place to ensure that SMS traffic to US end-users through long code phone numbers is verified and consensual.
How do I complete the Verification Process?
Follow the steps in this Telnyx article to verify your number.
If you are in the USA, you only need Level One verification.
If you are outside of the USA, you will need Level Two verification.
For toll free messaging you will need to request for level 2 verification.
This link provides you with information on how to request toll free messaging verification https://support.telnyx.com/en/articles/5353868-toll-free-messaging
