Received 3 phones calls the last 2 days and more over a month's time.  Finally talked to a person this morning, said he was with Iowa DR and was in the Hoover Bldg.  I asked him whose picture was on the wall and who were some of the state official.  Of course he did not know.  They said you owe Iowa money and want a front loaded debit card or transfer of funds.
They even have posted the 866 number as IDR number.  Complete scam mostly on immigrants but we don't fall into that category although we are older so probably phoning older people thinking they would be frightened if they did not sent the money.
