Creating another number with the same name does not restore the deleted resource, its identifier, or its previous connection. Deletion can involve cleanup, so an absent or pending number should not be treated as an invitation to repeat the action.
Contact support promptly with the deletion time, team, project, and the reference you still have. Explain whether you requested deletion or only stopped the number. Do not assume recovery is possible, and avoid sending another delete request while its result is unclear. Support will review the actual state before advising the next step.
