## Description

Invalid Phone Number

### Possible Causes

The request was received and failed during processing because a downstream provider indicated that the phone number is invalid, although the phone number formatting was valid. This can happen when the end user provides an invalid phone number in error, the phone number is deactivated, suspended, or in the grace period before reassignment, or a fraudulent user purposefully uses an invalid phone number.

### Possible Solutions

- Check that the phone number provided is correct.
- If using Silent Network Auth, retry Verification using a channel not based on phone number such as email.
