Telnyx 10DLC rejected: Opt-in / consent not described
Your Telnyx registration came back rejected and it points to opt-in / consent not described. Telnyx did not make that call. Here is what the reason means and exactly how to fix it.
Telnyx showed your A2P 10DLC campaign as rejected, and the reason maps to "Opt-in / consent not described". The part that trips people up: Telnyx did not decide this. It submitted your brand and campaign to The Campaign Registry (TCR) and the carriers, they returned the rejection, and Telnyx is relaying it back to you.
That is good news for the fix. Because "Opt-in / consent not described" is a carrier and TCR requirement rather than a Telnyx rule, the correction is the same no matter which provider you registered through: The #1 rejection cause. The campaign must describe exactly how end users consent to receive messages, and the consent must be verifiable.
Where Telnyx shows this rejection
Telnyx surfaces brand and campaign status in the Mission Control portal under its Messaging / 10DLC area, along with the reason returned for a rejected registration. That reason originates with TCR or the carriers.
Telnyx is the messenger, not the decider
Rejections can happen at the brand level or the campaign level, and they mean different things. A brand-level rejection is usually an identity problem such as an EIN and legal-name mismatch. A campaign-level rejection is usually a messaging problem such as opt-in or sample messages. The Telnyx status tells you which layer failed.
The fix
Describe the opt-in method in detail (web form, keyword, point of sale, paper form) and capture a screenshot of the exact CTA. Consent must be explicit and not bundled with other terms.
Same rejection, different provider?
The reason is identical no matter who you registered through.
Common questions
Did Telnyx reject my 10DLC campaign for opt-in / consent not described?
No. Telnyx submitted your campaign to The Campaign Registry and the carriers, who returned the rejection. Telnyx relays the reason. You resolve the underlying issue and resubmit through Telnyx. The fix here: Describe the opt-in method in detail (web form, keyword, point of sale, paper form) and capture a screenshot of the exact CTA. Consent must be explicit and not bundled with other terms.
What counts as verifiable opt-in for 10DLC?
A deliberate customer action to agree to texts, collected at a specific, describable place (a web form checkbox, a text-in keyword, a point-of-sale prompt, or a signed paper form), with the consent language visible and not bundled with a purchase. You should be able to show a screenshot of that moment.
How do I resubmit after a Telnyx rejection?
Correct the issue, then resubmit the campaign for review through Telnyx. Every resubmission is re-reviewed and re-review typically takes one to four weeks, so fix every problem before you resend rather than resubmitting to test it.
