If you’ve forgotten your Citi card PIN, you can retrieve or reset it through the Citi online banking portal or mobile app. Log in to your account, navigate to the “Manage My Account” section, and look for the PIN retrieval option. If available, you may receive a temporary PIN via SMS or email. Alternatively, you can contact Citi customer service for assistance. They will verify your identity and guide you through the process of resetting your PIN. Remember to keep your PIN secure and avoid sharing it to protect your account.
