How Can You Tell a Scammer Number?

You can tell it’s a scammer number if a call from an unknown number asks for money, personal or financial information, or access to your accounts.

Several signs help to identify a scammer’s phone number. Scammers often manipulate information like the area code to appear legitimate. They may use tactics like spoofing, where they fake the caller ID to resemble a trusted entity.

Additionally, scam calls often involve urgent or threatening language, pressuring you to act quickly. Common scam scenarios include impersonating government agencies like the IRS or claiming a relative needs urgent financial help.

5 Best Ways to Identify Scammer Number

Many scam calls are obvious, especially if they are from a different country or continent where you have no friends, family, or associate business. But it will not always be so apparent. In the age where VoIP numbers are prolific, there is no sure and free way to be sure if any number is from a scammer. However, there are a few techniques you can use to identify whether or not it is a scammer number.

Check the Area Code

Be cautious of unfamiliar area codes, especially calls from 3-digit international area codes that are more likely to be scams, including 876, 555, 901, 809, and 473. Scammers often use these area codes to deceive individuals.

Use Caller ID

If you receive a call from a number you don’t recognize, let it go to voicemail. Scammers often use phone number spoofing to make it appear like they are calling from your local area. Some mobile devices even provide “scam likely” notifications for suspicious numbers.

Research the Number

Before calling back an unknown number, research it online. You can search the number on Google to see if it is reported as a scam number. Several websites track scam numbers, and a quick search may reveal if it’s a common scam number.

Be Wary of Urgency and Threats

Scam calls often involve urgent or threatening language, pressuring you to act quickly. If the caller demands immediate payments or threatens consequences like arrest, it’s likely a scam.

Use Scam Blockers

Some phone service providers offer scam blockers or apps like TrapCall that help identify and block scam calls. These tools can help you avoid answering calls from potential scammers.

If a scammer has your phone number, they can impersonate you, send malicious text messages and calls, create a digital profile of you, and sell it to others.
