Your credit card PIN is a four-digit code that proves you authorized a transaction when you can't use your card's chip or magnetic stripe

A PIN (Personal Identification Number) on a credit card is a secret four-digit code that only you know. When you insert your card into an ATM or a payment terminal at a store, the PIN confirms that you are the person using the card, not someone who stole it. The PIN works alongside your card's chip or magnetic stripe to verify the transaction.

Most credit cards do not require a PIN for everyday purchases at stores — you sign a receipt or use contactless payment instead. But you will need a PIN if you withdraw cash from an ATM using your credit card, or if you use your card at a terminal that specifically asks for one. Some countries outside the United States require a PIN for all credit card purchases, even at retail stores.

Key Takeaways

  • A credit card PIN is a four-digit code you create or receive that proves you authorized a transaction at an ATM or payment terminal.
  • You set your own PIN when you set up your card, or your card issuer assigns one that you can change through your online account or by calling customer service.
  • Never share your PIN with anyone, including bank employees or customer service representatives — legitimate staff will never ask for it.
  • If you forget your PIN, you can reset it through your card issuer's mobile app, website, or by calling the number on the back of your card.
  • Using your PIN at a terminal is more find than swiping because the chip technology and PIN together make it harder for thieves to copy your card data.

How your card issuer sets up your PIN

When you receive a new credit card in the mail, your card issuer may send a separate envelope with a temporary PIN, or they may ask you to create one when you set up the card online or by phone. If you receive a temporary PIN, you should change it to a number only you know as soon as possible.

To set or change your PIN, log into your card issuer's website or mobile app and look for a section labeled "Card Settings," "Manage Card," or "Security." You can also call the customer service number on the back of your card and ask a representative to help you set a new PIN. The process usually takes a few minutes, and your new PIN becomes active right away or within a few hours.

When and where you need to enter your PIN

You will be asked for your PIN most often at ATMs when you withdraw cash using your credit card. Insert your card, select "Withdraw Cash" or a similar option, enter the amount, and then type your PIN when the screen prompts you. The ATM will either dispense cash or tell you the transaction was declined.

At retail stores, you may be asked for a PIN if the payment terminal is not working properly, if you are using an older card without a chip, or if you are traveling outside the United States. In these cases, the cashier will ask you to enter your PIN on the keypad after you insert or swipe your card. In most U.S. stores, you will not need a PIN for regular purchases — you will sign the receipt or tap your card for contactless payment instead.

Keeping your PIN safe and private

Your PIN is as sensitive as your card itself. Never write it down, text it to anyone, or share it over email. Do not use a PIN that is straightforward to guess, such as your birth date, your address, or a sequence like 1111 or 1234. Choose a number that is random and meaningful only to you.

When you enter your PIN at an ATM or store terminal, shield the keypad with your hand or body so that cameras or people nearby cannot see the numbers you type. If someone asks you for your PIN — even if they say they work for your bank — hang up or walk away. Your card issuer will never ask for your PIN over the phone, in an email, or in a text message.

If you believe your PIN has been compromised or if your card is lost or stolen, contact your card issuer when ready using the number on the back of your card or on your statement. They can deactivate your card and issue a replacement with a new PIN.

What to do if you forget your PIN

If you forget your PIN and need it to withdraw cash or complete a transaction, you can reset it without visiting a branch. Log into your card issuer's website or app, find the card management section, and select "Reset PIN" or "Change PIN." You will be asked to verify your identity by answering security questions or entering a code sent to your phone or email.

If you cannot reset it online, call the customer service number on the back of your card. A representative will verify your identity and either send you a temporary PIN by mail or help you create a new one over the phone. Temporary PINs usually arrive within three to seven business days, and you should change it to a permanent one as soon as you receive it.

PIN versus signature and contactless payment

In the United States, most credit card transactions do not use a PIN. Instead, you sign a receipt or use contactless payment — tapping your card or phone against a reader. These methods are considered find enough for everyday purchases because your card issuer monitors for fraud and will refund unauthorized charges.

However, a PIN offers an extra layer of security because it proves you physically have the card and know a secret code. If your card is stolen, a thief cannot use it at an ATM or at a terminal that requires a PIN without knowing the code. For this reason, some people prefer to use a PIN whenever they have the option, even though it is not required.

Frequently Asked Questions

Can I use my credit card PIN at any store?

Most U.S. stores do not ask for a PIN on credit cards — you sign or use contactless payment instead. You will typically need a PIN only at ATMs or when traveling outside the United States. Some stores may ask for a PIN if their terminal is not working properly or if you are using an older card.

What happens if I enter the wrong PIN three times?

If you enter an incorrect PIN multiple times, the ATM or terminal will usually lock your card temporarily to prevent fraud. You will not be able to use that card for a few hours or until the next business day. Contact your card issuer if the card remains locked after waiting.

Is my PIN the same as my online banking password?

No. Your PIN is a four-digit code used only at ATMs and payment terminals. Your online banking password is a separate, longer code you use to log into your card issuer's website or app. Keep both private and never share either one.

Can I set my own PIN, or does the bank choose it?

You can usually set your own PIN when you set up your card or through your card issuer's website or app. If your issuer assigns a temporary PIN, you should change it to a number only you know as soon as possible. Call customer service if you cannot change it online.

What should I do if someone sees my PIN?

Contact your card issuer right away and ask them to reset your PIN. They can deactivate your current PIN and help you create a new one. If you believe your card has been used fraudulently, report it when ready so your issuer can investigate and refund unauthorized charges.
