They used to have an actual SEAL authenticator website. I think it was authentiseal.com or something. You'd just plug in the information and it would respond within 24-48 hours letting you know if said person was a SEAL
The Authenti-SEAL guys closed up shop and now run the SOCNET site. SEALs have the distinction of being the only special operations guys who've maintained a data base tracking each and every individual guy who graduated from BUD/S.
