• Use only the official site – Always type activate.uhc.com yourself instead of clicking links from texts or emails.

• Watch for lookalike sites – Many unofficial "guide" websites copy the UHC look and feel. Don't enter your details there.

• Never share sensitive info – UHC won't ask for your full Social Security number or bank login just to activate a card.

• Verify suspicious messages – If a link looks slightly off, go to the site directly or call the number on the back of your card instead of clicking through.

• Keep your login secure – Use a strong password and don't share your account details with anyone.

• Check the URL carefully – Make sure the address bar shows the correct official domain before entering any personal information.

A few careful habits go a long way in protecting your personal and health information. Stick to the official website, stay alert for phishing attempts, and you'll be able to activate and use your UnitedHealthcare card safely.
