If you are a player then everything is restored. However, if you are a TD I believe that there is a clause that says that you can't let your membership expire or you lose your TD certification.
Expired USCF Membership

I let mine expire for three months a year ago. Now, I must renew when its is time because I rejoined just before a tournament that I prefer never to miss.
You do not lose anything except a couple of issues of the magazine, which no one reads anyway. You also need to reregister if you want to vote.
I believe there's some kind motto that goes "once rated, always rated"
No, you don't lose anything :) They'll just want to collect some $$ before you can enter a tournament.

So I literally have nothing to worry about if I just renew it tonight or whatever? It's like I never let it expire?

Cool...I got it. Same member #, too?
Same here, I renewed online about an hour before a tourney in the hotel lobby once. It all worked out.
Yeah, you keep your number.

I'm curious as to why you don't like the magazine.

Awesome. Thank you again.

I think it's interesting enough, too.

I like the magazine. But when it arrives, most of the news is something that I read several months ago. Recent exceptions include the issue with Walter Browne on the cover and the issue with an article about Kenneth Regan.
That's two good articles in one year.

I let my membership expire for 19 years...came back to the same number and same rating.
Haha, really? Cool...

Mine was expired for fourteen and they had no records of my previous existence. I rejoined in 1995. Mine has expired several times since. Last year's three month gap was the longest in the past twenty years.

I thought the Second Golden Age of American Chess article was OK. lol

It was just a weird flukey thing that I happened to remember my membership number for all those years.
I got busy around the New Year and had to go out of town on short notice. I let my USCF membership expire after December 31st. What happens now? Do I lose my ratings? What if I just go and purchase the membership again? Will they activate my old member # and just pick up where I left off or will I be assigned a new member #?
Thanks
