numbers.not_found
The phone number was not found or is not owned by the active workspace.
numbers.not_found is returned when a number lookup, routing update, or release operation targets a number ID that does not exist or is not assigned to the requesting workspace. The platform enforces workspace isolation on number records.
The number ID does not exist, was released, or belongs to a different workspace.
Verify the number ID against the list returned by GET /v1/numbers. Ensure the request uses the correct workspace context.
