The one listed for Vermont doesn't work, unfortunately.  

I would try and go on line and type in the state and you might just see the number you are requesting. If not you will most likely see the telephone number you can call and get the number you need.

Sometimes the 1099g worksheet is weird, make sure youre inputting the number at the top of the form, inputting at the bottom will make an error even though the error youre seeing without the number takes you to the bottom of the form....you still need to enter it at the top.
