ERROR: 30034
Description
This message appears when a user tries to send SMS messages using a newly registered A2P 10DLC (Application-to-Person 10-Digit Long Code) number in the U.S., but the registration process has not been fully completed. While the brand and campaign may be approved, the carrier-level provisioning can take additional time, during which SMS sending attempts may fail.
Possible Causes
- Pending Carrier Registration: Even though your A2P campaign has been approved, it can take up to 24 hours for the number to be fully registered and activated with mobile carriers.
- Premature Messaging Attempt: The error may show if you attempt to send messages during this propagation period before the number is fully ready.
- Incomplete A2P Setup: In rare cases, your registration might still be under review or partially submitted.
Possible Solutions
- Wait 24 Hours: After A2P approval, wait up to 24 hours before sending SMS messages to ensure the number is fully registered across all carriers.
- Avoid Sending Messages During Propagation: Do not test or use the number until the waiting period has passed to prevent errors.
- Verify Registration Status: Check your A2P registration and phone number status in the Trust Center or Phone Number Settings.
- Contact Support if Issue Persists: If the error remains after 24 hours, reach out to support with your registration and number details for further assistance.
