If you are producing the mailing yourself, send us a standard University of Iowa requisition that has your nine-digit mail code and the number of pieces in the mailing written on it along with the mailing. If Printing Services will be delivering the mailing to us, send us a requisition when you place your printing order. Alternatively, you may include the mailing instructions on your printing requisition and send a copy of it to us. Be sure write on your requisition that the job should be delivered directly to Mailing Services. Then call to let us know it is coming. We will process it and deliver it to the Post Office.
