Scams using the O2 name
Phone, broadband and energy providers send bills every month, so a fake bill blends right in.
Bill overdue or big discount
Messages claim your bill is overdue, or offer a large discount or refund, to get you onto a fake payment page.
SIM swap
Scammers convince a provider to move your number to their SIM, then receive your security codes. A sudden loss of signal is a warning sign.

Step by step
How to check a message that claims to be from O2
- 1
Look at the actual sender address, not just the name. Tap or hover over the name to reveal it. It must end in @o2.co.uk, or a subdomain of one.
- 2
Do not use links or phone numbers from the message. Type o2.co.uk into your browser or open the official O2 app, and check your account there.
- 3
Slow down when you see urgency, small fees, gift cards, crypto, or requests for codes and passwords. Those are the levers every scam pulls.
- 4
Still unsure? Paste the sender address or link into the checker above.
Questions
O2 scam FAQ
What email address does O2 use?
Genuine O2 email comes from addresses ending in @o2.co.uk, or a subdomain of those (for example something@mail.o2.co.uk). An address on any other domain, even one containing "o2", is not O2.
Can scammers fake an @o2.co.uk email address?
We are running the first check on o2.co.uk. Until then, assume a sender address alone proves nothing and verify by visiting o2.co.uk yourself.
Are there websites pretending to be O2?

What should I do if I clicked a link in a fake O2 message?
Do not enter anything else. If you typed a password, change it at o2.co.uk straight away and turn on two-step sign-in. If you entered card or bank details, call your bank using the number on your card. Then report the message using the guide below.
