Just to muddy the waters there is also genuine Nordost that does not have serial numbers, even if it should. For example cable cut down from longer lengths, even if done by Nordost with their connectors, may not have a S/N, and certainly not if done by a third party. Plus the serial numbers can fall off -- I owned a Valhalla power cord which had S/N via a black sticker that got detached, while Nordost would accept the cable as genuine they would not generate a new S/N
Net net there is no substitute for close inspection and review of the offered cable -- most fakes are obvious if you have a copy of the genuine article on hand
