N.D. Cent. Code § 8-03-07: Freight not delivered to consignee - Obligation of carrier

If for any reason a carrier does not deliver freight to the consignee or the consignee's agent personally, the carrier shall give notice to the consignee of its arrival and keep the same in safety, upon the carrier's responsibility as a warehouseman, until the consignee has had a reasonable time to remove it. If the place of residence or business of the consignee is unknown to the carrier, the carrier may give the notice by letter dropped in the nearest post office.
