Strict. Only the servers o2.co.uk lists may send its email, everything else fails.
DMARC is the rule a domain owner publishes telling mail servers what to do with email that pretends to come from them. The stronger it is, the more likely scammers switch to lookalike domains, which is why the next section matters.

We check misspellings, look-alike characters, and the O2 name combined with words like “billing”, “bill”, “account” across common domain endings. A registered lookalike is not proof of a scam: companies often register typos of their own name to protect customers. But you should never trust a message from one.

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.

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?
None. o2.co.uk publishes no DMARC policy, so email pretending to come from @o2.co.uk is not blocked by this check. Treat the address alone as no proof.
Are there websites pretending to be O2?
On 14 October 2026 we checked 130 lookalike domain names and found 9 registered. 1 appear to be owned by O2 or a brand-protection service, 0 are parked or for sale, and 7 could not be linked to O2 while hosting a website or accepting email. A registered lookalike is not proof of a scam, but any message from one deserves suspicion.
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.
