Troubleshooting

Common Errors

Error	Cause	Solution
Brand verification required	Sole proprietor brands need phone verification	Check email/SMS for PIN, run telnyx 10dlc brand verify <id> --pin <code>
Campaign rejected: insufficient description	Description too vague	Be specific about message purpose, include business context
Sample messages must include opt-out	Missing STOP instructions	Add "Reply STOP to unsubscribe" to sample messages
Phone number already assigned	Number linked to another campaign	Run telnyx 10dlc unassign +1... first
Brand pending	Still under review (24-72h typical)	Wait and check status with telnyx 10dlc brand get <id>
Invalid use case for sole proprietor	Some use cases restricted	Sole prop limited to: 2FA, CUSTOMER_CARE, DELIVERY_NOTIFICATION, ACCOUNT_NOTIFICATION
Rate limit exceeded	Too many API calls	Wait 60s and retry
