# Delete phone number assignment

`DELETE /api/relay/rest/registry/beta/numbers/{id}`

Removes one phone-number assignment from its US 10-digit long code (10DLC) campaign by assignment ID. Use it when the number should stop sending traffic for that campaign; this does not release the phone number from the project or delete the campaign.
