DMV. You just hand them to someone at the front desk, they toss them in a box, and give you a receipt.

That said while i have heard stories of people getting hassled for not returning them, i must have a half dozen sets down in my basement from over the years, and have never had an issue.

The issue is if someone gets them and uses them. Once you hand them in, they are marked as surrendered in the database.

There is a drop box as well. You can simply drop it in and they send you a receipt after a few days.

Police office at Eatontown DMV told me drop boxes are now locked for security reasons. I just dropped off a set on Monday - had to go to the desk.

DMV will even send you the old ones if you want and they'll usually have hole or specific mark if I remember correctly that's what happened to me last year.

I used the drop box at Kilmer (Edison) to surrender plates yesterday.

You need to surrender them to any DMV.

To my house, I’ll just cover my plates w em Free tolls baby! Thanks a bunch friend

This happened to me. I had no idea they were supposed to be turned in, and through the years, I don't know what I did with them, but I just got a ticket for street cleaning in Jersey City. It was my plate from 15 years ago, on a car that was not mine, and now I have to plea by mail (I just have to send a copy of my license and registration).

There's a DMV office in Airport Plaza in Hazlet. I just dropped off my dads plates the other day and was in and out in less than 5 minutes, mostly because the lady in front of me made the person behind the counter explain things 3x.

I have some from years ago I just kept. Dropped some off at dmv and never got a receipt
