10 things to know about vishing (before you get that call)

Your phone rings. Caller ID shows it’s your bank. A warm, professional voice says there's unusual activity on your account. Everything about the call feels legitimate — and that’s exactly how scammers convince people to hand over sensitive information, send money, or give access to their accounts.

Vishing scams don’t just create confusion. They can lead to real financial loss. That’s why it’s important to understand how these calls work from start to finish before you get one. Here’s what you need to know about how vishing works, why these scams are costing people money, and what to watch for before a caller pressures you into making a costly mistake.

1. It's phishing, just by phone.

Vishing (voice + phishing) is when a scammer calls and pretends to be your bank, the IRS, tech support, or even someone you know, all to try to talk you into handing over money or personal information.

2. Caller ID can lie to you.

Seeing your bank’s name or grandma’s number on your screen isn't proof it's your bank or your grandma. Scammers can spoof caller ID to display any name or number, including a customer service line of a bank, family, and even law enforcement. 

3. Technology can now clone a real voice.

With just a few seconds of audio being pulled from a video, voicemail, or social post, scammers can recreate someone's actual voice down to tone, accent, and even the way the person pauses.

4. Scammers might already have some of your real details.

It’s all too easy to buy leaked information from past data breaches. Your name, email, and even the last four digits of your card can all be sourced. A caller volunteering a few correct details or getting a few answers right isn't proof they're legitimate.

5. Vishing is growing fast, and the money is real.

Vishing attempts have surged sharply over the past year as AI has made convincing fake calls cheap to produce. Americans field well over a billion scam calls every month, and for many victims, these calls don’t end in annoyance — they end in stolen funds, compromised accounts, or stolen payments that can be difficult or impossible to recover.

6. Urgency is the pressure point, but you don’t have to act.

Instead of devising a clever and convincing story, scammers rely on making you feel rushed saying things like "Your account will be frozen" or “This has to happen right now." Pressure is the scam hard at work, not a sign that the crisis is real.

7. Vishers may ask you to provide a one-time code you just received by text or phone.

Your trusted institutions won’t. If a caller asks for a verification code that was just texted to your phone, hang up. The scam can include a text message and a phone call.

8. The ask always comes last.

Every vishing call builds toward one moment the request that you provide some piece of information. It may be a code, a password, a transfer, or a gift card. Everything before that — the friendly tone and the conveyance of urgency — exists to soften you up for the ask. 

9. It’s ok to hang up mid-call.

You don't owe a caller the rest of the conversation, no matter how far in you are or how legitimate they've sounded. 

10. Always call back on a number you already trust.

Use the number on your card or on the organization’s or institution’s official website — never use a number the caller gives you, even if they offer to "transfer" you to someone else.

If something about a call ever feels off, trust that instinct. A callback to a trusted number on file, like that of your local branch, to confirm the legitimacy of a call is a small price to pay for peace of mind, and we'd always rather you double-check.
