How do I identify the account Customer Administrator?

The first user to sign into the account is the first Customer Administrator by default. 

Since MarketValues is a single user service, the login and password received when the service was first set up should be retained, and can be used to login as the Customer Administrator at https://extapps.nada.com/NADAOnline

For those services that can have multiple users, multiple Customer Administrators can be assigned.

The identity of the last account customer administrator to login is listed on the upper right of the main Values Online screen reached after logging in.

If you don't know any of your account Customer Administrators, or have forgotten your username and password, please call Customer Service at 800-544-6232 between 8:30 a.m. and 6 p.m. Eastern, M-F.
