If you have any numbers at all in your license plate, then the LAST NUMBER defines you as odd or even. If your license plate is 3A7F2C the letters are irrelevant – you are even because the LAST NUMBER is even. However, if you have no numbers and only letters on your plate, such as on a vanity plate, then your vehicle is considered odd.
Municipalities can set their own rules, so you might want to check with your town. WPIX news reports, “Montclair Township Council passed an ordinance specifying that license plates ending in letters A-M would be considered odd, while letters N-Z would be considered even.”
