Quick answer

StopScam helps users evaluate the context around suspicious phone calls: what the caller claimed, what they asked for, whether a text or link followed, and what to do before responding. The app is the ongoing protection layer for repeated unknown calls.

What to check

Caller claims about banks, government agencies, delivery problems, tech support, prizes, or family emergencies.

Voicemails that demand urgent callback, payment, account verification, or secrecy.

Follow-up texts or links that arrive after a suspicious call.

How to use it

Step 1

Paste the voicemail transcript, callback request, number context, or follow-up text into the checker.

Step 2

Use AI chat if you need plain-English guidance on urgency, impersonation, or payment pressure.

Step 3

Install the app if unknown calls are a recurring problem on your phone.

Useful for

  • People deciding whether to call an unknown number back.
  • Users receiving bank, IRS, delivery, or tech-support-style phone pressure.
  • Families helping older relatives slow down before sending money or sharing codes.

Frequently asked questions

1 Can StopScam identify every scam phone number?

No tool can identify every number with certainty. StopScam helps evaluate the message, context, and warning signs so you can make a safer callback decision.

2 What should I do if the caller says my account is at risk?

Hang up, do not share codes or passwords, and contact the company using an official number you find yourself.

3 Should I paste a phone number into the checker?

You can include the number and the caller message, but the caller claims and requested action usually matter more than the number alone.
