# 11018: Display name must not be a phone number

Log Type: TWILIO

## Description

The display name submitted in the bundle is a phone number, which is not permitted.

### Possible causes

* The provided display name is a phone number rather than a business name or identifier.

### Possible solutions

* Review and update the display name to ensure it does not contain a phone number and accurately reflects the registered business. Resubmit the registration for re-verification.
