I needed to pay an invoice based upon my temporary license plate number when I didn't have a Toll tag. Once I received my actual license plate, I made a toll tag account, but I couldn't pay the invoice online since the account wasn't linked to my temporary plate number. I called NTTA to link the accounts and pay the toll. They gave me a lower price as if I originally had a toll tag. The lady who helped me was very kind.
