What to Include in your Report

You are a very important source of information about claimants and employers who may be committing fraud. You can choose whether to include your name with your report or to remain anonymous. Knowing who you are will help us gather additional details, if needed. If you wish to remain anonymous, please do not include any information the claimant could use to identify you.

To be sure that we can adequately investigate, be sure to include as much of the following information as possible (if you do not know the answer, don’t worry, just tell us what you do know):

  • Who is committing fraud?
  • What is their full address?
  • The claimant's Social Security number?
  • The claimant's phone number?
  • What are they doing? (working? running a business? living in another country? unable to work?)
  • When did they start doing this?
  • If they are working - what is the Employer's Name?
  • Where is the employer located?
  • What is the employer's address and phone number?
  • Who else knows about it?
  • Your name, address and phone number (optional).
