How to check a O2 website
Look at the actual website address in your browser, not just the organisation name, logo, page design or wording. A page can look familiar while being hosted on a completely different website address.
GenuineWebsite compares the actual hostname with the website addresses held for O2. An address that merely contains “O2” is not automatically a genuine O2 website.
Why check a O2 link?
O2 is associated with phone, broadband or communications services. Unexpected links can arrive through email, text messages, search results, adverts or social media. Checking the website address gives you a simple identity check before you continue.
GenuineWebsite answers a narrow question: does the website address match a verified website address held for the organisation it appears to represent?
