The Wizard World Authentication Service ("WizAuth") is the premier and exclusive authentication service provided by Wizard Entertainment, Inc. Items authenticated by WizAuth are physically verified on the date of the actual signing at a Wizard World event to ensure authenticity. Unless stated otherwise in the product description, all pre-signed items from our Vault ship with a physical WizAuth COA and unique serial numbers are uploaded into the WizAuth verification database. (Note that Virtual Experience autographs do not include a WizAuth COA).
