In case of an error message or defect on the toll device, we need the following information:

  • Toll device serial number, (eg 030000123456789)
  • License plate, (e.g. RO-TT-123, please indicate the registration number in the format in which it is visible on the vehicle registration document, i.e. if the OBU is registered without a space/hyphen, please indicate this here as well.)
  • Exact date and time (time zone) of the error message (e.g. 01.02.2021; 08:03, please note the format DD.MM.YYYY for the date).
  • Error Code (e.g. 12001)
  • Country in which the error message incurred, (in the form "toll domain" e.g.: BG)
  • Reason for checking


On this basis, the error messages / defects are checked in cooperation with our technical department. As soon as the check is done, we will inform you of the result immediately.
