Telnyx 10DLC rejected: STOP response not provided or non-compliant
Your Telnyx registration came back rejected and it points to STOP response not provided or non-compliant. 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 "STOP response not provided or non-compliant". 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 "STOP response not provided or non-compliant" is a carrier and TCR requirement rather than a Telnyx rule, the correction is the same no matter which provider you registered through: A STOP keyword must confirm opt-out and state that no further messages will be sent.
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
Provide STOP copy confirming the user is unsubscribed and will receive no further messages from the brand.
Same rejection, different provider?
The reason is identical no matter who you registered through.
Common questions
Did Telnyx reject my 10DLC campaign for STOP response not provided or non-compliant?
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: Provide STOP copy confirming the user is unsubscribed and will receive no further messages from the brand.
What should a 10DLC STOP reply say?
It should confirm the person is unsubscribed and will receive no further messages from your brand, in plain language and under 320 characters. Naming the brand and offering HELP is good practice.
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.
