# 30926: Campaign rejected: Multiple companies or brands cannot be registered under a single campaign

Log Type: APPLICATION

Log Level: ERROR

## Description

Your A2P 10DLC campaign was rejected because the campaign registration references multiple companies or brands. Each A2P 10DLC campaign must represent a single brand sending messages for a single use case. Carriers require a one-to-one relationship between a campaign and the brand it represents. If your business operates multiple brands or sends messages on behalf of multiple companies, each must have its own separate campaign registration.

### Possible causes

* **Multiple brand names in campaign details:** The campaign description, sample messages, or opt-in materials reference more than one company or brand name.
* **Shared campaign across subsidiaries:** A single campaign is being used to send messages for multiple subsidiaries or business units that operate under different brand names.
* **ISV sending on behalf of multiple clients:** An ISV (Independent Software Vendor) registered one campaign but intends to use it for multiple end-client brands.

### Possible solutions

* **Create separate campaigns** for each brand or company that will be sending messages. Each campaign should represent exactly one brand.
* **Ensure consistency** across all campaign fields: the brand name, sample messages, opt-in materials, and website should all reference the same single company.
* **For ISVs:** Register individual campaigns for each client brand using the appropriate brand registration. Review Twilio's ISV documentation for multi-brand registration guidance.
* **Resubmit the campaign** with references to only one brand throughout all campaign materials and fields.
* **Contact support** if you believe this rejection is incorrect: [Twilio Support](https://support.twilio.com).
