That's an OLD account number (seeing as mine is 75128)
Don't take this the wrong way, since I love both parties involved
But when was the last time you used the account?
I could be wrong (and have been in the past on numerous occasions) but didn't ARS get rid of a lot of inactive accounts back in 2003 when the big changes happened?
Right or wrong, sponsors, boards, paysites, etc. delete accounts that haven't been active in X amount of days/months/years - especially if there's a big server or database move & they don't want to spend time importing dead accounts.
Just a thought

Jay - I've had to call ARS in the past & they were very helpful.
If it's the W9 thing, just print one up form the IRS website & fax it into:
