The 4 digit PIN on a debit card is not printed or located anywhere on your debit card or even credit card.
The debit card and credit card PIN numbers are secret numbers that you must create when you activate your debit card or credit card.
If you forget your 4 digit PIN for your credit card or debit card you often reset it through the credit card website or if a debit card PIN, you can often reset your debit card PIN number or create one on your online banking account.
You can also call your banks customer service number to reset your 4 digit secret PIN number for your debit card.
Or if you're using a credit card you can call the credit card company's customer service and reset the 4 digit PIN number.
You should also never keep your PIN number for your debit card or credit card in your wallet with your debit card or credit card.
If you keep the PIN number for your debit card or credit in your wallet along with the credit card or debit card, and you lose the wallet, someone would have access to your PIN number and be able to easily use your credit card or debit card to withdraw money.
However, while there's no actual 4 digit PIN on a debit card or credit card, there is a 3 digit or even sometimes 4 digit number located on the back of the card, which is called a CVV number, if that is what you mean.
The CVV number, which is also known as the Card Verification Value, number is a 3 or 4 digit security code that is used for verifying if you have the physical card with you during phone transactions or online transactions.
For Visa, Mastercard and Discover cards, the 3 digit CVV number is located on the back of the card, near the signature panel.
And for American Express, the 4 digit CVV number is printed on the front of the card, just above the main card number.
