Messaging Registration
Messaging registration is the first place to check when SMS or MMS cannot send, is filtered, or is not ready for launch.
Before you begin
- Complete business profile, brand registration, and campaign setup.
- Use policy URLs and opt-in language that match the real customer experience.
- Avoid broad SMS outreach while registration is pending or rejected.
Where to find it
Open Phone -> Trust Hub to review business profile, brand, and campaign status. Open Messages to test sending only after registration is ready.
Step-by-step
- Check Business Profile status.
- Check Brand Registration status.
- Check Campaign Registration status.
- Read any rejection or failed-state details shown in Trust Hub.
- Fix the specific issue, such as legal mismatch, missing policy, weak consent flow, or unrealistic sample messages.
- Retest messaging after status updates.
What happens next
- Provider and carrier review can take a few business days and can vary.
- Approved registration improves deliverability but does not guarantee delivery of every message.
- Content, consent, links, recipient behavior, and carrier policies still affect filtering.
Best practices
- Prepare A2P details before porting a number that will depend on text messaging.
- Keep campaign use case and live message content aligned.
- Use real opt-in language and screenshots or examples where the registration process asks for them.
Troubleshooting
- If texts fail immediately, check whether campaign status is pending, rejected, failed, or unsubmitted.
- If only some messages fail, inspect content and links.
- If registration status is unclear, refresh Trust Hub and wait for reconciliation.
