# PHONE_NUMBER_HAS_MESSAGES_SENDING

> Messages still sending

| HTTP status | Retryable |
| - | - |
| `409` | Yes |

## What happened

Your number has messages to this group that are still sending.

## How to fix it

Wait until they finish, then retry.

> [!TIP]
>
> This error is safe to retry. Wait for the `Retry-After` header when it is present. If the endpoint takes an `Idempotency-Key`, reuse the same key so a retry never creates a duplicate.
