# 23005: Phone Number Redaction Incompatible Configuration: Fallback to Long Code

Log Type: APPLICATION

Log Level: WARNING

## 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/api/service-resource).
* If Fallback to Long Code functionality is needed, implement this functionality in your own application.
