**HTTP status:** `422`. May also be reported as a field-level finding in `error.details[]`.

One or more phone\_number\_ids are unknown, belong to another account, or belong to the other test/live mode. Nothing was created or changed.

## Troubleshooting

- Choose ids returned by GET /v1/phone\_numbers using the same credential and mode.
