You may have experienced “spoofing” if you’ve ever checked your Caller ID, assumed it was a friend or neighbor, and picked up the phone only to be greeted by a telemarketer.

The practice known as “spoofing” is used by unscrupulous businesses to mask their true identity by altering the name and number on your Caller ID. Their main goal is to make you believe it’s someone you know or local to your region, so you’ll answer the phone and listen to their sales pitch or scam.

How Does Phone Spoofing Work?

Scammers may use phone number spoofing to seem like their calls are coming from a reliable company. Many consumers nowadays ignore calls from 1-800 numbers, numbers with foreign area codes, or numbers without caller ID information because they are suspicious of the source.

If you use a smartphone, you may get a call from a number slightly different from your own, such as one with the same area code but a different number. They may even use your name and number to show up on your caller ID system. Spoofing is used in many types of scams by con artists.

Types of Phone Number Spoofing

There are several situations in which a person could be a witness to a phone spoofing incident. We have gathered a list of spoofing techniques that con artists use to deceive many customers.

  • Banking Scams: Scammers posing as bank employees contact you and claim there’s been an issue with your account, and they need your financial details to fix it. This individual wants your data so they can steal your money.
  • Technical Support Scams: A fraudster phones you, stating an issue with your computer. They may attempt to bill you for bogus repair services, or if you grant them remote access, they may attempt to install malware or other malicious software.
  • Prize Opportunity Scams: Someone calls to tell you that you won a reward through a lottery. They’ll tell you that you must pay a little upfront charge to collect the reward. But, when you pay the price, the fraudster vanishes with your money.
