Am in NJ and have used toll systems in other states - De, Pa, Fl, Md. The tolls show up on my EZPass statement. I would think your EZPass usage would show up on your NC statements / bills if an agreement between the systems is in place. Make sure your lic plate and vehicle is registered on your NC account (am assuming they do that). NJ likes to include a $50 admin fee if they have to send you a letter to collect the toll. If your transponder is not read correctly, they will waive the admin fee if your vehicle is registered on your account and only collect the toll.
