Toll-Free and A2P Basics
A2P 10DLC and toll-free messaging registration help carriers understand who is texting, why they are texting, and whether recipients gave consent.
Before you begin
- Know whether your sending number is local 10DLC or toll-free.
- Prepare legal business identity, consent language, policy links, and sample messages.
- Avoid customer outreach before the proper registration is approved.
Where to find it
Use Phone -> Trust Hub for business profile, brand, and campaign setup. Number management lives under Phone -> Numbers.
Step-by-step
- Complete the business profile.
- Register the brand when required.
- Register the messaging campaign with a real use case and consent flow.
- Assign messaging numbers to the appropriate inboxes.
- Send test messages only after registration status is acceptable.
- Monitor delivery issues and carrier filtering symptoms.
What happens next
- U.S. carriers require businesses to register many SMS/MMS use cases before traffic is trusted.
- Registration helps deliverability but does not override bad content or missing consent.
- Toll-free and local-number requirements can differ, so follow the status and fields shown in Waveline.
Best practices
- Complete registration before porting or launching a number that will depend on SMS.
- Keep privacy and terms pages live and accurate.
- Use one campaign per real messaging use case when your business has distinct needs.
Troubleshooting
- If SMS is blocked, check Trust Hub and campaign status first.
- If a ported number cannot text immediately, confirm the number is attached to an approved messaging setup.
- If carrier review rejects the campaign, fix the reason rather than changing only the wording.
