I've still got an ICQ number that works, though I've not used it (prior to today) in at least a decade, probably two. Eight-digit starting with 1, so probably 1997-1998?

I had a very low 7 digit number and the earliest I would have created the account was late summer 1997. My recollection is it was hockey sticking at the time, so that boundary between 97/98 seems spot on.
Got a 6 digits, too, starting with 1. so I'd say your one sounds about right.
I remember that ICQ was the "hot new thing" on Christmas and New Year in the phreaking scene back then. I signed up pretty early, dunno if it was late November or early December though.
