EVS is another identity/age verification service like Bluecheck and Veratad. They appear to store personal information once they've collected it (a red flag in my book) here's the disclosure excerpt from their privacy policy;
Disclosure
We may disclose any of the information we collect from or about you (as described above) to the following types of entities upon written request: regulatory authorities; affiliated or partner companies, such as data bureaus; or an entity that has executed a service or product contract with Electronic Verification Systems for purposes of providing our software solution(s).
We do not disclose the personal identity information data you provide to us via our online software to any third party for any marketing purposes. We do not sell, trade, or distribute the information we collect from you to outside vendors or third parties unrelated to the services provided by Electronic Verification Systems. This type of information may be disclosed to authorized regulatory authorities, upon request, as required by law.
Here's a link to their privacy policy in its entirety; Privacy Statement | Electronic Verification Systems (EVS)
They do make multiple references to using a person's S.S.# for verifications and imply it enables them to exceed minimum regulatory compliance (second red flag in my book). Identity Verification | Electronic Verification Systems (EVS) Home
Crap!
