What Are Spam Calls?

Spam calls are unsolicited phone calls, usually made by automated systems (robocalls) or scammers. These calls may:

• Promote fake products or services
• Attempt phishing attacks (stealing personal data)
• Impersonate government or financial institutions
• Use “spoofed” numbers to appear legitimate

Some common types include:

• IRS or Social Security scams
• Tech support fraud calls
• Fake loan or insurance offers
• “Your car warranty is expiring” calls

Why You’re Receiving Spam Calls

Understanding the source helps you stop them more effectively.

1. Your Number Is Public

If your phone number is listed online (social media, websites, directories), it becomes an easy target.

2. Data Breaches

Companies you’ve signed up with may have leaked or sold your data.

3. Random Number Dialing

Robocall systems automatically dial thousands of numbers—even if yours was never shared.

4. App Permissions

Some apps collect and share your phone number with third parties.
