The GRTU lease info states to go to GRTU to validate.
“ To validate your record and eligibility, go to the GRTU webpage, http://www.grtu.org, anytime between August 5th and August 31st and follow the instructions on the website. You will need to know your TU membership number to validate your record. You will also be required to enter your vehicle license plate number on your record.”
It would be interesting to know if there is a system crash or if spots are being taken up.
