a plurality of distribution items at a plurality of distribution facilities and a plurality of beacons each of the plurality of distribution items having one of the plurality of beacons thereon;
one or more sensors arranged at each of the plurality of distribution facilities configured to detect a plurality of identifier signals emitted from the beacon on each of the plurality of distribution items;
a central hub having a memory, the central hub configured to:
receive, at a plurality of distribution facilities, a plurality of beacons and a plurality of distribution items, each of the plurality of distribution items having one of the plurality of beacons thereon;
detect, by sensors at each of the plurality of distribution facilities, a plurality of identifier signals emitted by the beacons, each of the plurality of beacons emitting one of the plurality of identifier signals;
associate, in a memory each identifier signal of the plurality of identifier signals with a unique serial number corresponding to one of the plurality of beacons, and with an identifier of a distribution facility of the plurality of distribution facilities where the identifier signal was detected;
