International Revenue Share Fraud (IRSF)

International Revenue Share Fraud (IRSF) is perpetrated by people exploiting parts of the world that are extremely expensive to deliver phone calls to. Oftentimes, fraudulent companies acquire expensive international phone numbers and sell them to whoever will pay for them.

These companies are often referred to as International Premium Rate Number Providers (IPRN). They buy cheap circuit connections to reputable carriers, so they can make money for each call that terminates on the phone numbers they have acquired. Then, people will buy the expensive international phone numbers from the IPRNs and have their workers robo-dial calls to these phone numbers. The money will start to flow in when the calls are placed from a location in the United States.
