Business Identity Theft

What is Business Identity Theft? 

Business identity theft (also known as corporate or commercial identity theft) is a type of identity theft. It occurs when someone uses a business’ identity to establish lines of credit with banks or retailers.

Identity thieves could be attempting to manipulate state business registration and filing systems to gain control over the business, fraudulently employ people or claim unemployment benefits, or conduct other business in that company’s name. In some cases, identity thieves assume the identity of a business for criminal purposes like money laundering and racketeering.     

Regardless of the thieves’ intent, business identity theft can be detrimental to a company’s reputation, deter customers, cause financial loss, cause expensive litigation, and even potentially lead to bankruptcy.
