# 30902: Campaign rejection - A DCA2 rejected this campaign registration request.

Log Type: APPLICATION

Log Level: ERROR

## Description

This error means your A2P 10DLC campaign registration was rejected during third-party review. To approve a campaign, you must provide accurate campaign details that explain who is sending messages, who receives them, why the messages are sent, and how recipients opt in, opt out, and get help.

### Possible causes

* Your campaign description is too vague or does not clearly explain the sender, recipient, and purpose of the messages.
* Your opt-in workflow or call to action is incomplete or unclear. Common gaps include missing consent details, missing opt-out instructions, missing HELP details, missing message frequency disclosure, missing privacy policy information, or missing "message and data rates may apply" language when required.
* Your sample messages do not match the selected campaign use case, or they do not match the registered brand, website, or stated messaging purpose.
* The website or business details in the registration are invalid, inaccessible, under construction, misspelled, or inconsistent with the business you are registering.
* The campaign was flagged for prohibited or high-risk content, or for another non-compliant registration issue that cannot be approved as submitted.

### Possible solutions

* Review the campaign `failure_reason` in Console or API and update the specific fields that were rejected. In many cases, you can correct the campaign details and resubmit the same campaign for another review.
* Rewrite your campaign description so it clearly states who is sending messages, who receives them, and why the messages are being sent.
* Fix your opt-in flow so it clearly documents how recipients consent to messages. Include the required disclosures for your use case, along with clear HELP and STOP instructions where applicable.
* Update your sample messages, use case selection, brand details, and website so they are accurate and consistent with each other and with the actual traffic you plan to send.
* If the issue is tied to prohibited content, an unsupported use case, or a problem with the associated Brand rather than the campaign text itself, correct the underlying issue before submitting a new campaign. If you believe the rejection was made in error, contact Support with your campaign and account details.
* If you only need to correct campaign details, resubmit the edited campaign instead of deleting and recreating it. Rejected campaigns can be updated and sent through vetting again.
