Search a caller ID or text-message number against scam alerts. Optionally paste what they said for script-pattern matching (IRS, Medicare, Zelle refund trick, etc.).
Not law enforcement. A blank index result does not mean the caller is safe — hang up and call back on an official number.
Quick answer
Use Phone Scam Checker when you need a fast second opinion on a caller ID or text-message number. Paste the number, optionally add what they said, and we compare it against published scam alerts plus common IRS, Medicare, utility shutoff, and Zelle refund scripts.
How the Phone Scam Checker works
- Enter the number exactly as it appears (include country code when you can).
- Optional: paste a short summary of the call or SMS script.
- Review matches from indexed alerts and pattern labels.
- If it looks familiar, hang up and call back on an official number from your bill, card, or .gov site.
Spoofed caller ID is common. A blank result does not prove the caller is legitimate — it only means we have not indexed that number yet.
When to use this tool
- Utility shutoff threats demanding same-day payment
- Medicare or Social Security "benefits suspended" calls
- Bank / Zelle "refund trick" callbacks
- Tech-support or package-delivery robocalls with a local-looking number
