For one thing the above answer is not correct. A Federal EIN can never be used as a state ID.
The box 13 state ID is only necessary if there was state tax withheld in box 12. If box 12 is blank or zero then all boxes 12-14 must be blank. If there IS a dollar amount in box 12 then contact the issuer of the 1099-R for a corrected form that has the required box 13 information.
