Error code
30521: Toll Free verification rejection - Opt-in data cannot be shared with third parties
Correctable and resubmittable. Stated by: Twilio error page for this code.
What this error means
Your submission indicates messaging consent itself may be shared, transferred, rented or sold.
Causes, most likely first
- Opt-in terms mention sharing data with non-affiliates or partners.
- Privacy policy or terms mention transferring messaging consent.
- Business practices involve sharing or selling consent data.
- No explicit protection for messaging consent anywhere.
How to fix it
If your numbers are managed by a platform
If your numbers sit inside a reseller platform, for example LeadConnector numbers inside GoHighLevel, you do not have access to the Twilio Console, and the interface shows the rejection without the code. Ask that platform's support team for the Twilio rejection error code, in writing, before you change anything. You can also read it yourself from your browser, which is faster: see how to get the code.
The substance of the fix is yours to make: the business details, the website, and the opt-in flow described in the Twilio path all belong to you, not to the platform. Make those changes first, confirm they are live, then ask support to resubmit. A resubmission filed before the underlying facts change will fail again on the same reason.
If you own the Twilio account
Remove all language permitting third-party sharing of opt-in data. Add the explicit carve-out: *"The above excludes text messaging originator opt-in data and consent; this information will not be shared with any third parties."* Keep consent a direct 1:1 agreement between consumer and sender, and make clear it can't be transferred or sold.
Timing and resubmission
Correctable, resubmit within seven days for priority review.
