Guys...
Best way to find out the your case number is call them up.. But I would restrain to call as it is not advisable being a beneficiary. I just found out my case number by calling automated system.. I had a date with me that I received from my lawyer... In my case, I just called the automated system and entered my employer phone number, it gave all the cases with receipt date. I figured out my case number with the receipt date which I received from my lawyer. Ofcourse! my company did not file any other cases in those dates, so I figured out..
Bad news...
Automated system gave couple of case numbers filed through my company.. I noticed, there was a case received in Jan first week of 2002 in regional and they also received Notice of Finding Rebuttal, but not yet made any decision.. All together they have four cases received before mine and they did not approve/reject any of them.. All them are still lying there for some time..
Just hope for the best..
Good Luck!!!
