Is your brand in these feeds?

New lookalike domains registered recently
Domains registered in the last 15 days that contain O2's name, sit one character away from it or use look-alike characters. Attackers often register these days before sending the first email.

How O2 phishing works
Phishing against O2 follows patterns common to telecom & internet. Typical lures:
- An "unpaid bill" or "service suspension" text with a payment link.
- A fake "account upgrade" or "free phone" offer that asks for card and PIN details.
- A notice that your email or voicemail is full that links to a cloned account page.
- A call or message about a SIM change that pushes you to verify your identity online.
Red flags
- Carriers rarely suspend service by text link with an hour's notice.
- The payment page is not on the provider's official site or app.
- You are asked for your account PIN, SSN or a one-time code to "restore" service.
Real O2 domains
If the address in your browser is not one of these (or a subdomain of them), it is not O2. The list is not exhaustive.
o2.co.ukIf you already clicked or entered details
Sign in only through the provider's official app or site, set or change your account PIN, ask the carrier to add a port-out lock, and check that no new lines or forwarding were added.
Protecting a brand like O2 from lookalike domains
If you run security, brand or fraud for a company that is copied this way, this is the order that works in practice:
- Enforce DMARC. Move your policy to quarantine, then reject, so attackers cannot send mail that passes as your domain.
- Watch new registrations. Lookalikes appear daily; the earlier you see one, the sooner you can act, ideally before the first email goes out.
- Register the obvious typos and keyword variants you can afford to hold, and check which lookalikes are already registered by someone else.
- Report fast. A live fake needs a request to the registrar and host, plus a report to browser safe-browsing lists and the public feeds shown above.
- Tell your customers where you will and will not ask for logins, codes or payments.
Protect your brand from lookalike domains
O2 is one of 579 brands in this index, but attackers copy any company whose customers log in or pay. PhishPin checks your domain for registered lookalikes, email-spoofing gaps and listings in these same phishing feeds, then helps you get the fakes taken down.
Audits use public data only – we never touch your servers. Results within 24 hours.
Questions about O2 phishing
How can I tell if a message from O2 is phishing?
Check the sender and link domain first. Carriers rarely suspend service by text link with an hour's notice. The payment page is not on the provider's official site or app. You are asked for your account PIN, SSN or a one-time code to "restore" service. When in doubt, do not use the link: type o2.co.uk into your browser or open the official app.
How many O2 phishing sites has PhishPin found?
As of 1 Nov 2026, 175 hostnames referencing O2 appear in the phishing feeds PhishPin indexes (274 reported URLs). These are reported hostnames, not a count of sites that are online today; many are removed quickly and some matches are coincidental.
What do fake O2 domains look like?
In our data, the most common ending for reported hosts is .com. The brand is most often combined with the word "billing". 31 hosts put the brand name in a subdomain of an unrelated site. Always read the part of the address just before the first single slash: that is the real site. Real O2 addresses end in o2.co.uk.
What should I do if I entered my details on a fake O2 page?
Sign in only through the provider's official app or site, set or change your account PIN, ask the carrier to add a port-out lock, and check that no new lines or forwarding were added.
How do I report a fake O2 website or message?
Forward phishing emails to reportphishing@apwg.org, report scams at reportfraud.ftc.gov, and report the page to Google Safe Browsing. Also tell O2 through the contact options on its official website (o2.co.uk).
Is it safe to visit the domains listed on this page?
No. They are shown defanged, with dots in brackets, so they cannot be clicked by accident. Do not type them into a browser. Listings are warnings from automated matching, and some are harmless coincidences.
How does PhishPin find lookalike domains of O2?
We read the daily list of newly registered domains (1,050,000 domains over the last 15 days) and flag those that contain the brand name, differ by one character or swap look-alike characters. A match is a warning sign, not proof of abuse.
How can a company protect its own brand from lookalike domains like these?
Publish an enforced DMARC policy so nobody can send mail as your domain, monitor newly registered domains that resemble your name, register the obvious typo domains, and file takedown requests with the registrar, host and browser safe-browsing lists when a fake goes live. PhishPin's free brand audit checks the first three for your domain.
