# E12086 — SMSSuppressionCarrierOwned

This suppression mirrors the carrier's own opt-out, so it cannot be removed.

- **HTTP status**: `422`
- **Type**: `validation_error`
- **Name**: `SMSSuppressionCarrierOwned`

## What to do

The subscriber's carrier reported the opt-out and remains the authority on it, so removing this record would not let the message through. It ends when the carrier reports the opt-out cleared.
