How To Check Phone Numbers And Websites An AI Gives You

Never call a phone number or open a website just because an AI answer or search result gave it to you. Scammers plant fake customer service numbers online, and AI can repeat them. Get contact details from the back of your card, a letter, the official app, or a website address you type yourself.

Quick Steps

  1. Get numbers from your card, a letter or the official app.
  2. Type website addresses yourself.
  3. Never give a PIN, password or code on a call you didn't expect.
  4. If in doubt, hang up and call back on a checked number.

Why Does AI Sometimes Give Fake Phone Numbers?

You ask Google or a chatbot for your airline's or bank's phone number. It gives you one. You call, and the friendly person on the line asks for your card details.

AI tools like Google's AI Overviews and ChatGPT build answers from what's on the web. If scammers have posted a fake "customer service" number in enough places, the AI can repeat it as if it were real. AI can also simply make up a number or web address that looks right. Google's own help page says AI Overviews can make mistakes.

What Is The Golden Rule?

Get contact details from a source you already trust: the back of your bank card, a printed bill or letter, the official app, or a website address you type yourself. Not from an AI answer, an advert or a search result.

How Do I Check A Phone Number?

  1. Find the official website by typing the address yourself, then look for "Contact us". Does the number match?
  2. Check your paperwork: the back of your card, a statement, a booking email or the company's official app.
  3. Be suspicious if the person asks for your full card number, PIN, passwords or one-time codes, asks you to install an app, asks for remote access to your computer, or rushes you.
  4. If in doubt, hang up and call back on a number you've checked, ideally from a different phone or after waiting a few minutes.
Got a phone number from AI? 1 Don't call it yet: AI can give out-of-date or fake numbers. 2 Find the real number on your card, a statement, a letter, the official app, or the official website typed in yourself. 3 Do they match? If not, use the number you found yourself. 4 Still unsure? Hang up, and never give a PIN, password or code on a call you didn't expect.
Check any number a chatbot gives you before you ring it.

How Do I Check A Website Is Real?

  • Read the address carefully. Fakes add extra words or dashes (like "chatgpt-login-help.com") or use a different ending (.co, .net, .shop).
  • Don't trust "Sponsored" results. Scammers sometimes pay for adverts at the top of search results.
  • Type well-known addresses yourself, like chatgpt.com or gemini.google.com, and save them as bookmarks.
  • Government sites end in .gov in the USA and .gov.uk in the UK.
  • Never pay to "unlock" a free AI tool. ChatGPT, Gemini and Claude all have free versions on their official sites.

Can I Ask The AI Where It Got The Number?

Yes. Ask: "Where did you get that phone number? Give me the link to the official page." Then open the link and make sure it's really the company's own website. If it can't show you, don't use the number.

What If I've Already Called A Fake Number?

  1. Hang up.
  2. If you gave card or bank details, call your bank straight away on the number on the back of your card and ask them to block the card.
  3. If you let someone into your computer, switch it off and get help from someone you trust before using it for banking again.
  4. Change any passwords you shared.
  5. Report it (below).

Where Do I Report A Fake Number Or Website?

UK

Common Questions

Google's AI gave me a number. Is it real?

Maybe, maybe not. Always check it against the company's own website or your paperwork before calling.

I called a fake number and gave my card details. What now?

Call your bank straight away, using the number on the back of your card, and ask them to block the card. Then report it.

How do I spot a fake ChatGPT website?

The real one is chatgpt.com, or the official app made by OpenAI. Be wary of any site that asks you to pay to unlock it or asks for card details before you've tried it.

Are sponsored search results safe?

Not always. Scammers sometimes pay for adverts at the top of search results. Type the company's address yourself instead.

How can I tell a government website is real?

US government websites end in .gov and UK government websites end in .gov.uk.
