[U.S. A2P 10DLC] Campaign Registration - Privacy Policy & Terms & Conditions URL Fields Now Available
To support compliance and improve campaign approval rates, Twilio is introducing new fields during U.S. A2P 10DLC Campaign registration.
What’s Changing?
When registering a Campaign, you must now provide:
- Privacy Policy URL – A valid, publicly accessible link to your privacy policy
- Terms & Conditions URL – A valid, publicly accessible link to your service terms.
These are now dedicated fields in the registration flow.
Console Updates
In the Twilio Console, you’ll see new fields in the Campaign registration form where you can enter your Privacy Policy and Terms & Conditions URLs directly.
API Updates
For programmatic registrations, these fields are now supported:
- Setup: Values can be passed during the Campaign create request. Providing the specific request header during the Campaign create call will return these fields in the API response.
- Recommendation: While the API currently allows flexibility, we highly recommend including these links in all new registration requests to avoid potential vetting failures.
Why This Matters
Previously, this information was required and requested within the Message Flow description.
Providing dedicated, direct links ensures your Campaigns get approved faster and reduce the risk of rejection.
To learn more about U.S. A2P 10DLC registration, please review our documentation and Support article on Campaign approval requirements.
