FFL validity...

Anyone knkw how to check if their ffl number is still valid without having the actual card?
I got mine in the late 80's, last used it around 94ish then physically lost in either in transit, moving or wherever.
Now that I'm living in a state which is more lenient with gun ownership I'm thinking of buying a few shotguns mainly for the range but not sure if mine's lapsed or if I've gotta do it all over again.
