Hello Shayjharris,
You can reach out to your human resource department or benefit administrator to access the self service enrollment site.

A common reason that verification/identification entries are not recognized is due to a typo or data issue. The best course of action in this case will be to contact your HR representative and confirm your personal data is correct in the system (or they may be able to create your account and grant you access).
