When a registration is denied, AWS End User Messaging provides a denial reason that explains why the registration was not approved. The following table lists all RCS registration denial reasons and the recommended action for each.


**RCS registration denial reasons**  

| Denial reason | Description | Recommended action |

Choose the RCS Agent assistance category and include your registration ID. See [Get more information through Support for registration issues](registrations-request-support.md). | 
| CANNOT\_UPDATE\_REGISTRATION | Certain RCS agent fields cannot be modified on an existing registration. | Create a new testing registration with the corrected fields. |

For denial reasons that require AWS Support assistance, create a support case in the [AWS Support Center](https://console.aws.amazon.com/support/home#/case/create?issueType=service-limit-increase). Include your AWS RCS Agent ID and registration ID in the case description.
