# Request Phone Number Release

Submit a release request for a phone number you no longer need. The request enters `pending` status and is reviewed before the number is actually released.

```

## Path parameters

<ParamField path="phone_number_id" type="string" required>
  UUID of the phone number to release.
</ParamField>

## Request headers

<ParamField header="Authorization" type="string" required>
  Bearer token. Format: `Bearer talq_your_environment_token_here`
</ParamField>

<ParamField header="Content-Type" type="string" required>
  Must be set to `application/json`
</ParamField>

## Request body

<ParamField body="reason" type="string" required>
  Reason for the release. Length: 10–500 characters. Helps support staff review the request faster.

## Notes

* Detach the number from any agents (via [Update Agent Calling](/api-reference/endpoints/update-agent-calling)) before requesting release.
* A pending request can be cancelled with [Cancel Release Request](/api-reference/endpoints/cancel-release-request).
* Once approved, the number is released and **cannot be recovered**.
