Is this phone number a scam? How to check a call or text in two minutes
4 min read · Updated October 2, 2026
Most crypto scams now start with a phone call or a text — sometimes a 'wrong number' message from a friendly stranger, sometimes a frightening call about your bank account. You can check any number before you engage, and you should.
Check the number before anything else
Paste the number into our free check at the top of this site. If someone in the community has already been contacted by it, their report will show you exactly what the caller tried.
Also search the full number in a fresh browser tab, in quotes, plus the word 'scam'. Scam numbers get used hundreds of times, and victims often post about them.
The signs that give it away
You usually do not need any tools at all. The conversation itself tells you.
- They contacted you first. Banks, exchanges and government agencies do not cold-call or cold-text you about crypto.
- There is urgency — an account problem, a deadline, an opportunity that expires.
- They ask you to move money, buy crypto, or share a code that was texted to you.
- They want to keep the conversation secret, or to move it to WhatsApp or Telegram.
- A 'wrong number' text turns into friendship, then into an investment tip.
If you already talked to them
Hang up and do not call back any number they gave you. If they claimed to be your bank or an exchange, find the official number on the back of your card or the company's real website and call that instead.
If you sent money or shared codes, act quickly: our guide on what to do after a crypto scam walks you through it step by step. And if you have a minute, report the number here — your report is what the next person finds when they check it.
