# Update the resource for a phone number

`PATCH /api/fabric/phone_number_addresses/{id}`

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.
