ALERT: When logging in for the first time, only, GVS National powered by Avēsis vision providers must create a new username and password. Click here to register, or see our FAQs for more information.


Avesis has replaced the TIN & PIN combination, which providers have been using to log into the system,  with a username and password. In order to implement our enhanced security measures, your initial user experience will include an extra step, but it’s one that is necessary.

Please review the Provider Portal FAQs before you begin.  To begin, click “Sign In.” You will log in with your TIN & PIN to make the changes. And just as you do now, if you have more than one location, you will need to create a unique username for each.
