Employer ID numbers are truly a pain. Same for the Document control number.
If a space is present try without a space.
Be careful that you didn't use a capital I for a 1 or vice versa.
If it has a dash (-) try without it.
Make sure if you copied and pasted it there is no space after the last character.
My experience: The Fed form required a space; the state would not accept a space character even though that was the way it was printed.
