Protect Yourself from Phone Scams & Spam Calls
Americans received an estimated 55 billion robocalls in 2024 alone, and scammers are getting more sophisticated every year. Spy Dialer's reverse phone lookup is one of the fastest free tools to check whether an unknown call is legitimate before you engage. Below are the most common types of phone scams and what you can do to stay safe.
IRS / Government Impersonation
Scammers posing as the IRS, SSA, or law enforcement threatening arrest or fines. Remember: real government agencies contact you by mail first, not by phone.
Tech Support Scams
Unsolicited calls claiming your computer has a virus. Legitimate tech companies never cold-call to fix your device.
Robocalls & Telemarketers
Pre-recorded messages about fake warranties, loan offers, or "prize" winnings. Hang up and run a reverse number search on the number.
Spoofed Caller ID
Scammers disguise their number to look local ("neighbor spoofing"). If the number seems familiar but the caller doesn't, run a phone number search before calling back.
One-Ring (Wangiri) Scams
A call rings once and disconnects, hoping you'll call back a premium-rate number. Never return a call from unknown numbers without checking them first.
