To check your California Lottery results and claim your winnings safely, start by visiting the official California Lottery website or using the official mobile app, where you can view the latest winning numbers and verify your ticket instantly. You can also check results at authorized retailers by scanning your ticket using a self-service machine or asking a clerk for assistance. If you’ve won, sign the back of your ticket immediately to protect it from theft or loss. For smaller prizes, you can claim your winnings directly at a retailer, while larger prizes require submission through a Lottery District Office or by mail with a completed claim form. Always ensure you use official channels and avoid third-party websites to keep your personal and financial information secure.
