A nonlicensee may ship a firearm by a common or contract carrier to a resident of his or her or her own State or to a licensee in any State. A common or contract carrier must be used to ship a handgun. In addition, Federal law requires that the carrier be notified that the shipment contains a firearm or ammunition, prohibits common or contract carriers from requiring or causing any label to be placed on any package indicating that it contains a firearm and requires obtaining written acknowledgement of receipt.
