YOM Pairs vs. Singles
We receive many requests from antique car owners requesting pairs of plates with which to register their antique cars under Year of Manufacture (YOM) laws. Check with your DMV to see what your state requires. Some states require original pairs, while others only require a single plate. Other states, like Illinois, allow you to use any state plate on your car (provided you have valid antique vehicle plates in your car).
Below is a list of how each state issued its license plates in the past. Obviously your DMV cannot require a pair for YOM if a pair was never issued. This can help guide you, but again your DMV is the final judge.
