Error code
30513: Toll Free verification rejection - Opt-in not sufficient: Language Unclear
Correctable and resubmittable. Stated by: Twilio error page for this code.
What this error means
Your consent wording doesn't clearly say the user is agreeing to receive text messages.
Causes, most likely first
- Opt-in language doesn't clearly ask for consent to messaging.
- Flow never explicitly mentions SMS or text messaging.
- Consent language buried in terms of service or privacy policy instead of shown in the opt-in flow.
- Doesn't make clear what messages the user is agreeing to.
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
Rewrite the opt-in so it explicitly asks the user to agree to receive SMS/text messages from your business. Keep messaging consent separate from accepting the privacy policy or terms. State what messages they'll get so consent is specific. Update the submission with publicly hosted images or URLs showing the full workflow and the exact text shown. Resubmit if the rejection is editable.
Timing and resubmission
Correctable, resubmit within seven days for priority review.
