The Federal Communications Commission adopted new rules on Tuesday in an effort to crack down on the practice of caller ID spoofing.

Spoofing is when a caller manipulates caller ID data to display a different phone number and identity.

The FCC is now requiring phone companies to implement a new system called SHAKEN. The system makes sure the caller ID data matches the actual number before the call can go through.

SHAKEN will also allow law enforcement to identify scammers more easily.

Phone companies must begin using the new system by June 30, 2021.
