That last number on your Massachusetts license plate isn’t just for show—it actually tells you when your car registration expires. For example, a plate ending in 3 means your registration is up in March. This clever system helps the RMV spread out renewals and avoid long lines. It’s also a quick way for police to check if you’re up to date. So, next time you look at your plate, you’ll know exactly when it’s time to renew. Have you ever been surprised by your expiration date? How do you keep track? #Cars #Massachusetts #CarTips
