Who runs it, and where
JSA lists phone lines in New Jersey and Florida on its website. [1]
Its business listing gives the address 2 Sylvan Way, Suite 102, Parsippany, NJ 07054. [2]
Online cert lookup
JSA offers an online "Verify Authenticity" lookup by certification number. [3]
A JSA business manager wrote publicly that new certifications took about a month to appear online during a period of high volume, so a missing result may just be a delay. [2]
Press and court history

What marketplaces and other authenticators say
As of Oct 12, 2026, JSA 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. [4]
