# 21731: Cannot perform operation on suspended brand

Log Type: APPLICATION

Log Level: ERROR

## Description

Your A2P 10DLC Brand is in a suspended state. You cannot create a new campaign with that brand or update the brand until the suspension is addressed. Brands with `SUSPENDED` status require Twilio Support assistance, and campaigns associated with a suspended brand are also suspended.

### Possible causes

* The traffic sent on the brand does not match the campaign use case that was registered.
* The brand or its campaigns were associated with spam, phishing, unsolicited messaging, or excessive consumer complaints.
* The traffic involved prohibited or high-risk content such as controlled substances, illicit or fraudulent activity, affiliate marketing, promotional gambling, or age-restricted messaging without the required age gate.
* The campaign registration details for purpose, workflow, opt-in, or opt-out did not adequately reflect the messaging program being run.

### Possible solutions

* Stop using this brand for new registration changes. Do not try to move the same traffic to another existing or new brand or campaign while the suspension is unresolved.
* Review your brand and campaign setup against the messaging you actually send. Make sure your campaign description, use case, message flow, opt-in method, opt-out handling, and help information are accurate and consistent with your live traffic. ([help.twilio.com](https://help.twilio.com/articles/11847054539547-A2P-10DLC-Campaign-Approval-Best-Practices))
* Remove or correct any traffic patterns that could trigger suspension, including spam-like messaging, prohibited content, affiliate marketing, gambling-related messaging, or age-restricted content without the required age gate.
* Check your email and the Twilio Support Center for guidance. If you have not received next steps, contact Twilio Support because suspended brands require support assistance to address.
