Caller ID Spoofing: When the Number Looks Real

Scammers can make any number or name appear on your caller ID, including your bank's. How caller ID spoofing works, why it succeeds, and why calling back is the answer.

Your phone rings and the screen shows your bank's name, or the number printed on your card. Surely it is them. Not necessarily. Caller ID spoofing lets a caller choose what number or name appears on your screen.

How spoofing works

Internet-based phone systems let callers set the caller ID they send. Criminals use this to display:

  • your bank's genuine customer service number
  • a police station or government office
  • a local-looking number ("neighbour spoofing")
  • a family member's number

Caller ID is not proof of identity. A matching number on your screen means nothing on its own.

Why it succeeds

  • People are taught to check the number, and it matches.
  • Combined with personal details, the call feels completely genuine.
  • Callers even invite you to "check the number on your card", knowing it matches.

The answer: call back

  1. End the call politely.
  2. Find the number yourself: on your card, statement, the official app or website.
  3. Call from a different phone if possible, or wait a few minutes.
  4. Ask if they called you.

Reduce spoofed calls

  • Turn on your phone's or network's spam call filtering.
  • Let unknown numbers go to voicemail.
  • Report scam calls to your network or national service.

Frequently asked questions

Can scammers really show my bank's number?

Yes. Caller ID can be faked, so a call can show a bank's genuine number or name. That is why you should call back on the number on your card.

What is neighbour spoofing?

Faking a number that looks local, often with the same area code and first digits as yours, to make you more likely to answer.

Is anything being done about spoofing?

Some countries require carriers to verify caller ID or block spoofed calls, which helps but has not eliminated spoofing.
