Who runs it, and where
Upper Deck says every UDA autograph is witnessed by a UDA representative, and that each item gets a serial-numbered hologram and a matching COA. [1]
Upper Deck says items from before 2002, and many show or event items ("SHO" prefix), may not appear in the online database. For those, contact customer care. [3]
Press and court history
Sterpka v. The Upper Deck (Cal. Ct. App.): the appeals court affirmed judgment for the defendants (per the case listing). [4]
What marketplaces and other authenticators say
As of Oct 12, 2026, Upper Deck does not appear on eBay's published list of people and organizations whose COAs/LOAs are not allowed. That list is not an endorsement, and eBay says COAs are only as valuable as the reputation of the issuer. [5]
