Who runs it, and where
PSA/DNA is the autograph authentication division of PSA (Collectors). Its listed autograph shipping address is 1600 E. St. Andrew Place, Santa Ana, CA 92705. [1]
Online cert lookup
PSA runs a public Cert Verification page for PSA and PSA/DNA numbers. The number is on the oval DNA sticker or the label. [2]
PSA itself notes that verifying a number "does not eliminate risk", because counterfeiters sometimes copy real certification numbers. [2]
Press and court history
In Cardregistry, Inc. v. Collectors Universe, Inc. (E.D.N.Y. 2024), a case alleging misauthentication, the court dismissed the claims (per the published case summary). [3]
Sterpka v. The Upper Deck (Cal. Ct. App.) involved PSA/DNA's parent and Upper Deck; the appeals court affirmed judgment for the defendants (per the case listing). [4]
What marketplaces and other authenticators say
As of Oct 12, 2026, PSA/DNA 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]
PSA offers an eBay-specific QuickOpinion service. [6]
