Your credit card PIN is a four-digit code that proves you own the card when you use it at an ATM or in person at a store

A PIN (personal identification number) is separate from your card number, expiration date, and CVV. It is a code only you should know. When you enter it at a machine or payment terminal, the bank verifies that the person holding the card is actually the cardholder.

Most credit cards do not require a PIN for everyday purchases in stores or online. You use your PIN mainly at ATMs to withdraw cash or at certain payment terminals in other countries. Some cards let you set a PIN; others do not offer one at all. Whether your card has a PIN depends on the card issuer and the card type.

Key Takeaways

  • Your credit card PIN is a four-digit code you create or receive from your bank, used mainly at ATMs and some in-person terminals.
  • Most credit cards do not require a PIN for regular store purchases or online transactions in the United States.
  • You can set or change your PIN through your bank's website, mobile app, or by calling customer service.
  • If you forget your PIN, contact your card issuer directly — they can reset it or send you a new one by mail.
  • Never share your PIN with anyone, including bank employees or customer service representatives.

When you actually need your credit card PIN

You need your PIN when you withdraw cash from an ATM using your credit card. Insert the card, select the withdrawal amount, and enter your PIN to complete the transaction. The ATM will dispense the cash and charge it to your credit card account as a cash advance, which typically comes with a higher interest rate and an upfront fee.

In some countries outside the United States, payment terminals at stores require a PIN instead of a signature or chip verification. If you travel internationally, ask your card issuer whether your card has a PIN and whether you can use it at foreign merchants. Many U.S. credit cards work without a PIN abroad, but having one available is useful as a backup.

Some credit cards issued by smaller banks or credit unions may require a PIN for in-person purchases, but this is uncommon. Check your card's terms or contact your issuer if you are unsure.

How to set or change your credit card PIN

If your card issuer offers PIN protection, you can usually set or change your PIN through your online account. Log in to your bank's website or mobile app, find the card settings or security section, and look for a PIN option. Follow the prompts to create a four-digit code that is not your birth date, address, or other easily guessed information.

If you cannot find the PIN option online, call the customer service number on the back of your card. A representative can walk you through the process or set a temporary PIN that you can change later. Some issuers mail a PIN to your address on file when you first open the account.

Change your PIN if you think someone else knows it, if you have not used it in a long time, or if you straightforward want a new one. The process is the same whether you are setting it for the first time or updating an existing PIN.

What to do if you forget your PIN

Call the customer service number on the back of your card and tell the representative you have forgotten your PIN. They will verify your identity by asking for your card number, the last four digits of your Social Security number, or other personal information. Once verified, they can reset your PIN or send you a new one by mail.

If you need the PIN when ready, ask whether the issuer can give you a temporary PIN over the phone that you can change online later. If the issuer mails a new PIN, it typically arrives within five to seven business days. Until then, you can still use your card for regular purchases and online transactions — you just cannot withdraw cash from an ATM.

Protecting your PIN from theft

Treat your PIN like you treat your password. Never write it down, never share it with anyone (including bank employees or family members), and never tell it to someone who calls or emails claiming to be from your bank. Your bank will never ask for your PIN.

When you enter your PIN at an ATM or payment terminal, shield the keypad with your hand or body so nearby people cannot see the numbers. If a terminal looks damaged or unfamiliar, do not use it — find another ATM or contact your bank.

If you suspect someone knows your PIN or has used your card without permission, contact your card issuer when ready. They can cancel the card, issue a replacement, and investigate any fraudulent charges.

PIN versus other card security features

Your PIN is one layer of security, but it is not the same as other protections on your card. Your CVV (the three-digit code on the back) is used for online and phone purchases. Your signature or chip verification is used at store checkout. Your card number and expiration date are needed for any transaction.

Each of these serves a different purpose. The PIN proves you have the physical card and know a secret code. The CVV proves you have the card in hand for remote transactions. The chip or signature proves you are present at the store. Together, they make it harder for someone to use your card without permission.

If your card does not have a PIN, you are not at a disadvantage — most U.S. credit cards work fine without one. The chip and your signature (or contactless payment) provide enough security for everyday use.

Frequently Asked Questions

Is my credit card PIN the same as my online banking password?

No. Your PIN is a four-digit code used at ATMs and some payment terminals. Your online banking password is what you use to log into your account on the bank's website or app. They are separate and should be different. If your bank asks you to use the same code for both, change one of them when ready.

Can I use my debit card PIN on my credit card?

No. Each card has its own PIN. If you have both a debit card and a credit card from the same bank, they have separate PINs. You set or change them independently. Using the wrong PIN will not work and may lock you out of the terminal temporarily.

What happens if I enter the wrong PIN three times?

Most ATMs will retain your card or cancel the transaction after three incorrect attempts. If the ATM keeps your card, contact your bank to retrieve it or request a replacement. If the transaction is cancelled, wait a few minutes and try again with the correct PIN, or call customer service for help.

Do I need a PIN if I never use ATMs?

No. If you never withdraw cash and do not travel internationally, you may never need a PIN. Your credit card works for purchases and online transactions without one. However, having a PIN available is useful as a backup in case you need cash in an emergency or travel abroad unexpectedly.

Can someone use my credit card if they know my PIN?

At an ATM, yes — they could withdraw cash. At a store, they would also need the physical card. Online, they would need your card number, expiration date, and CVV, not your PIN. If you suspect someone knows your PIN, contact your card issuer right away to cancel the card and prevent unauthorized withdrawals.
