Rejected due to "Payor EIN does not match IRS records

[pugunruh]

We have received w2gs from several casinos across the country for years and have never had an issue.  I have tried 5 different ways to e-file my federal return along with 3 different states and have been rejected each time.  It is showing only the w2s from Harrah's North Kansas City.  I checked the info filed last year and made sure everything was identical on federal and state info.  The casino says nothing has changed from last year.  HELP

Try to enter 99-0999999. Let us know if this works.

Really?  Does this work? I guess as a last resort, I will try it.  The casino looked at their 1120 filing and said try putting a hyphen after the first word.  At this point I will try anything. Will let you know.

CRAZY!!  It worked.  Along with all 3 states.  Probably will have to prove it later,  I can handle that.  THANKS!
