Learn how scammers manipulate caller ID information to appear legitimate and what you can do to protect yourself from spoofing attacks.
Caller ID spoofing is a technique that allows scammers to disguise their phone number and make it appear as if they're calling from a trusted source.
Spoofing involves manipulating the caller ID display to show a different number than the actual calling number. Scammers use this to appear as local businesses, government agencies, or even your own phone number.
Scammers use VoIP technology and specialized software to alter the caller ID information transmitted with their call. This technology is surprisingly accessible and inexpensive, making it a popular tool for fraudsters.
Scammers often spoof local numbers to increase answer rates, as people are more likely to answer calls from their area code. They also impersonate banks, utility companies, and government agencies to gain trust.
One prevalent tactic is the "neighbor scam," where the caller ID shows a number with your same area code and prefix. This makes the call appear to be from someone in your neighborhood or community.
While spoofing itself isn't always illegal, using it to defraud or cause harm is a federal crime. The Truth in Caller ID Act prohibits spoofing with intent to defraud, cause harm, or wrongfully obtain anything of value.
Never trust caller ID alone. Verify caller identity through independent means before sharing information. Use call authentication services like Trustify that can detect spoofed numbers and warn you of potential fraud.
