I've had mine laminated for almost fifty years.

I'm pretty sure that they removed the restriction on lamination at some point. But I'm not really sure.

Canada issues their SSN cards in hard plastic, which IME is far superior to any credit card plastic. It’s been in my wallet since 1990 and while it looks old, it’s in better shape than almost all of my credit cards - none of which are older than 5 years.

I've kept mine in a tight card slot in a leather wallet for longer than some of these commentators have been alive and it honestly still looks great.

SSA will give you a free replacement card. I think TRUMP wanted to charge money for it, but not sure if that plan went through.
