Forgetting your Citi card PIN can be inconvenient, but retrieving it is straightforward. Start by logging into your Citi account online or through the mobile app. Navigate to the "Account Services" or "Card Services" section, where you can find options for managing your PIN. You might be prompted to verify your identity through security questions or a one-time password sent to your registered email or phone. If you prefer, you can call Citi's customer service for assistance. Once verified, you can reset your PIN easily. Always choose a secure and memorable PIN to avoid future issues.
