title: 2054: Environment has no sending line. | API Docs
description: The key's environment holds no number that can send.
---

**HTTP status:** `422`.

This key was issued into an environment, and a key only ever sends from numbers currently in its own environment. None of the account’s registered sending numbers is in this one, so nothing was sent and nothing was stored. Unlike no\_sending\_number, this is yours to act on.

## Troubleshooting

- Move a number into this environment where the account’s numbers are managed, then send again.
- Or send with a key that acts in an environment holding a sending number; GET /v1/phone\_numbers under each key lists what that key can send from.
