# Update the resource for a phone number

PATCH https://%7BYour_Space_Name%7D.signalwire.com/api/fabric/phone_number_addresses/{id}
Content-Type: application/json

Renames a phone number address, re-points its channel to a different resource, or both; omitted fields keep their current values. The channel itself is fixed: `handler_type` can't be changed, so to hand a number's other channel to a resource, update that channel's own address. Renaming the address also renames the phone number.A `422` response names the problem in its `code`:- `invalid_parameter`: `name` is not URL-safe or is longer than 256 characters.
- `provided_id_is_unrecognized`: `resource_id` is not a resource in your project.
- `invalid_resource_type`: the resource can't handle this address's channel.This API is in beta and may change.#### PermissionsThe API token used to authenticate must have the following scope(s) enabled to make a successful request: *Calling*, *Fax*, *Messaging*, or *Video*.[Learn more about API scopes](/docs/platform/your-signalwire-api-space).

## Authentication

- `Authorization` header (basic auth, required) — SignalWire Basic Authentication using Project ID and API Token. The client sends HTTP requests with the Authorization header containing the word Basic followed by a space and a base64-encoded string of project_id:token. The project ID will be used as the username and the API token as the password. Example: ``` Authorization: Basic base64(project_id:token) ```

## Request

### Path parameters

- `id` (string, required) — Unique ID of a phone number address.

### Body (application/json)

This endpoint expects an object.

- `name` (string, optional) — New name for the phone number address — lowercase letters, numbers, underscores, and hyphens only (no spaces or other special characters), up to 256 characters. Also renames the phone number. Defaults to the current value when omitted.
- `resource_id` (string, optional) — ID of the resource that should handle the channel from now on. Must be a resource in your project of a type that can handle the address's channel. Defaults to the current value when omitted.
