The Government Printing Office (GPO) requires signature authorization for all persons who are authorized to sign and submit printing and binding requisitions (SF-1’s) to GPO. This is critical to ensure statutory requirements are met and to prevent fraud.

Include the agency, bureau, department, office, billing address code (BAC), point of contact and telephone number for each person. Please indicate if the person is a new addition and notify us of any personnel changes that affect this list as they occur.
