Verify number ownership
Completes the number ownership verification challenge that registering the number started. Submit the code delivered by the verification call. An incorrect code is rejected.
If the verification call could not be started previously, this request can retry it and place another call to the same number. Your organization must still meet the identity-verification requirements for registering verified numbers; otherwise the request returns 412. For an expired or exhausted challenge, delete the verified number and register it again, which places a new verification call, and submit the new code against the ID the registration returns.
A successful ownership check is retained even when organization eligibility prevents outbound activation. If the verified number's status is verified after a 412 or 503, complete the missing steps or contact support, then resubmit an empty object ({}). The saved proof is reused without checking a code again. While proof is still pending, include the code; an empty object is rejected. A 412 means missing verification steps or an eligibility decision requiring support; a 503 means assessment is pending or unavailable. outbound_enabled indicates whether activation has completed. Outbound calls remain subject to routing and number ownership requirements.
Activation attempts to enable the number's country as a Voice destination. An unavailable country or a failed settings update can leave it disabled. Check Voice > Destinations before calling; see the verified number guide.

Headers
Client-supplied key. On operations supporting request deduplication, a retained response is replayed for duplicate requests with the same key within the idempotency window (3 hours by default). This protection requires a workspace, organization, or staff-account scope. User-only and unscoped unauthenticated operations, streams, and operations with a separate replay contract do not use this response replay.
On a supported operation, if idempotency protection is unavailable before execution, the API returns 503 IdempotencyUnavailable (E01033) without executing this attempt. Retry with backoff using the same key and request. An operation that takes effect before its response is retained can still execute again on retry.
Two distinct 409 errors signal misuse:
- request_in_progress (E01004): The same key is currently being processed by a concurrent request. Wait briefly and retry. The lock expires within 30 seconds.
- idempotency_key_reuse (E01005): The same key has already completed against a different request body or method. Generate a new key.
Recommended key format is <event-type>/<entity-id> (for example welcome-user/usr_abc123).
Workspace context for the request. Required for dashboard authentication and master keys. Workspace keys and access tokens already identify their workspace; send that workspace or omit the header. A different one is rejected.
Organization context for the request. Required for dashboard authentication. An API key or access token carries its own organization, so send either that organization or no header at all; a different one is rejected.
