  23005: Phone Number Redaction Incompatible Configuration: Fallback to Long
  Code
level: WARNING
product: Programmable SMS

## Description

Phone Number Redaction is enabled for your account. Fallback to Long Code is not compatible with Phone Number Redaction and should be disabled.

### Possible Causes

- You have Fallback to Long Code enabled on your Messaging Service. Fallback to Long Code requires Twilio to retain non-redacted phone numbers of recipients, and is incompatible with Phone Number Redaction.

### Possible Solutions

- Disable Fallback to Long Code on your Messaging Services using the [Twilio Console](https://www.twilio.com/console/sms/services) or the [REST API](/docs/messaging/services/api).
- If Fallback to Long Code functionality is needed, implement this functionality in your own application.
