Error 30035: Number Not Fully Registered for A2P
What this error means
Error 30035 means A2P registration isn't fully complete for the sending number. Your brand and campaign may show as approved, but carriers can still be provisioning the number. Messages may fail until the number is recognized across all carrier networks.
Common causes
- The brand and campaign were approved recently.
- Carrier provisioning is still in progress.
- The number hasn't fully propagated across carrier networks.
- Messaging started immediately after approval.
How to fix it
- Wait up to 24 hours after approval before sending from the number.
- Confirm the number is linked to the approved campaign in Settings → Phone System.
- Send a single test message after the waiting period.
- If the error continues after 24 hours, contact support with the number and campaign details.
Tip
Plan launches so that new numbers have a day to finish provisioning before you start campaigns or automations.
