First: Don’t Reply Right Away

Replying to a scam text — even just “STOP” or “wrong number” — confirms your number is active and monitored by a real person. That makes you a bigger target. With unknown texts, your safest first move is to pause and verify.

The Most Common Unknown-Number Text Scams

• Fake delivery alerts. “Your USPS/FedEx package is held — confirm your address here.” The link steals your details.
• Bank fraud alerts. “Suspicious activity detected. Verify your account now.” Real banks never text links asking for logins.
• Wrong-number friendship scams. A friendly stranger “accidentally” texts you, builds rapport over days, then pitches a crypto “opportunity.”
• Prize and refund bait. “You’ve won!” or “You’re owed a refund — claim here.”
• Verification code requests. Someone asks you to share a code you just received. Never do this.

How to Check an Unknown Number Safely

1. Don’t click any links. Scam links lead to fake login pages built to harvest passwords.
2. Search the number on Google in quotes — other people often report scam numbers publicly.
3. Run the message through a checker. Our free Scam Checker flags the exact warning signs in seconds.
4. Verify with the real company. Call the number on your bank card or the official website — never the number in the text.
5. Block and report. Block the sender and forward scam texts to 7726 (SPAM) in the US.

What If You Already Clicked or Replied?

• Change passwords for any account you may have exposed.
• Call your bank immediately if you entered card or login details.
• Watch for unexpected charges and set up account alerts.
• Report it at reportfraud.ftc.gov.

Frequently Asked Questions

Should I block every unknown number?

Not necessarily — but block any number that sends links, asks for money or codes, or pressures you. When unsure, don’t engage.

Can opening a text infect my phone?

Simply reading a text won’t install malware. The danger is clicking links or downloading attachments inside it.

Why do I keep getting scam texts?

Your number was likely exposed in a data breach or sold to spammers. Reporting and blocking helps reduce them over time.

Bottom line: treat every unexpected text as unverified until you’ve checked it. When in doubt, run it through our free Scam Checker before you respond.
