This exploratory study estimated the extent to which potential identity theft was used to obtain Supplemental Nutrition Assistance Program (SNAP) benefits in Florida and Missouri during a 12-month period (June 2016 to May 2017). The prevalence of potential identity theft was estimated from examining the SNAP caseload data for cases with data discrepancies requiring referral to the state SNAP agency for further investigation. Because identity theft can be truly determined only after a detailed fraud investigation is conducted, the study estimates are to be considered potential identity theft rather than true identity theft.
