What Is PIN (Personal Identification Number)?
Definition
A secret 4-digit code used to access your bank account at ATMs and authorize debit card purchases. Never share your PIN with anyone.
Example: "I chose a PIN that isn't my birthday or any number someone could guess."
Why It Matters
Your PIN is a critical line of defense for your bank account. Anyone with your debit card and PIN can withdraw cash from your account at any ATM. Choose a PIN that's not easily guessable, avoid birthdays, addresses, or sequences like 1234. Never write your PIN on your card or carry it in your wallet. When entering your PIN at an ATM or checkout terminal, shield the keypad with your hand. If you suspect someone has learned your PIN, change it immediately through your bank's app or by calling customer service.
