## Description

Phone Number Redaction is enabled for your account. Sticky Sender is not compatible with Phone Number Redaction and should be disabled.

### Possible Causes

- You have Sticky Sender enabled on your Messaging Service. Sticky Sender requires Twilio to save the non-redacted phone numbers of recipients, and is incompatible with Phone Number Redaction.

### Possible Solutions

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