Call the National Insurance Crime Bureau (NICB) at 800-835-6422 between 7 a.m. and 7 p.m. Central time, Monday through Friday.
Or, you can fill out the online form through the NICB website: https://www.nicb.org/how-we-help/report-fraud.
Because each state provides its own resources and processes for reporting fraud, you may find it helpful to contact your local FBI office instead. Find your nearest office using the FBI’s website: https://www.fbi.gov/contact-us/field-offices.
