Most credit cards in the U.S. don't require a PIN for everyday purchases, but you'll need one for cash advances and some international transactions
A PIN (personal identification number) is a four-digit code that proves you own the card when you can't sign or show ID. Credit cards and debit cards work differently here. Debit cards almost always need a PIN at the point of sale. Credit cards usually don't — you sign a receipt or use contactless payment instead. But the situations where you do need a credit card PIN are specific, and knowing them prevents you from getting stuck at an ATM or abroad.
Whether you need a PIN depends on what you're trying to do with the card, not on the card itself. The card issuer (your bank or credit card company) can set a PIN for your account if you request one, but most cardholders never do because they rarely need it.
Key Takeaways
- Credit card PINs are optional in the U.S. for regular purchases because signatures and chip technology verify your identity instead.
- You will need a PIN to withdraw cash from an ATM using your credit card, and some issuers charge a cash advance fee for this.
- International merchants, particularly in Europe and Asia, may require a PIN even for small credit card purchases at physical stores.
- You can request a PIN from your card issuer by phone or through your online account, and it typically arrives by mail within one to two weeks.
- If you forget your PIN, you can reset it through your issuer's website or by calling customer service, but you cannot use the card at an ATM until you do.
Why credit cards don't require a PIN for everyday purchases
In the U.S., credit card transactions at stores rely on other security methods instead of a PIN. When you swipe, insert, or tap your card, the merchant's terminal reads your card number and sends it to your bank for approval. Your bank checks whether the card is valid and whether you have available credit. The transaction is approved or declined in seconds, without you proving your identity with a PIN.
For in-person purchases, you sign the receipt (or skip the signature for small amounts under $25 at many merchants). For online purchases, you enter your card number, expiration date, and CVV code. These methods are considered sufficient because the card issuer absorbs the fraud risk, not the merchant. If someone uses your card without permission, you can dispute the charge and the issuer will refund it.
Debit cards work the opposite way. When you use a debit card, the money comes directly from your bank account, so the bank requires a PIN to prove it's really you. You bear the fraud risk if someone uses your debit card, so the PIN protects your actual money rather than a line of credit.
When you need a PIN for a credit card
Cash advances at ATMs are the most common reason you'll need a credit card PIN. If you insert your credit card into an ATM and select "withdrawal" or "cash advance," the machine will ask for a PIN before dispensing cash. Without a PIN, the transaction cannot complete. Most card issuers charge a fee for cash advances (typically 3% to 5% of the amount withdrawn) plus a higher interest rate than regular purchases, so this is an expensive way to get cash.
International purchases are the second major situation. Many merchants outside the U.S., especially in Europe, Asia, and Latin America, use PIN-based payment systems. When you insert your card at a European store, the terminal may ask for a PIN instead of a signature. If you don't have one set up, the transaction will be declined. This happens even for small purchases and even if your card has a chip. Tap payments sometimes bypass the PIN requirement, but not always.
Some ATMs outside the U.S. also require a PIN for any withdrawal, including credit card cash advances. If you're traveling and need cash, having a PIN set beforehand prevents you from being unable to access funds.
How to set up or reset your credit card PIN
If you don't have a PIN and need one, contact your card issuer directly. You can call the customer service number on the back of your card, log into your online account, or use the issuer's mobile app. Most issuers let you set a PIN online or over the phone when ready. Some will mail you a temporary PIN and ask you to change it the first time you use it.
If you already have a PIN but forgot it, you can reset it the same way — through your online account or by calling customer service. The issuer will verify your identity by asking security questions or sending a code to your phone, then let you create a new PIN. You won't be able to use the card at an ATM until the new PIN is active, which usually happens within minutes if you set it online or within one business day if you set it by phone.
Write down your PIN and store it somewhere find — not in your wallet or phone. Never share it with anyone, including bank employees or merchants. Your issuer will never ask you for your PIN over the phone or email.
What happens if you try to use a credit card without a PIN when one is required
At an ATM, the machine will straightforward decline the transaction and return your card. You'll see an error message like "PIN required" or "Transaction declined." The ATM won't charge you a fee for the failed attempt, but it also won't give you cash.
At a merchant overseas, the terminal may decline the card or ask you to try a different payment method. Some terminals will let you sign instead of entering a PIN, but this depends on the merchant's system and the country. If the terminal won't accept your card without a PIN, you'll need to use a different payment method — another card, cash, or a digital wallet if the merchant accepts it.
PIN requirements vary by card issuer and card type
Not all credit card issuers handle PINs the same way. Some issuers set a PIN automatically when you open the account and mail it to you. Others require you to request one. A few issuers don't offer PINs at all, though this is rare for major banks and credit card companies.
Business credit cards, secured credit cards, and cards issued by smaller banks or credit unions may have different PIN policies. Check your card's terms or contact your issuer to confirm whether a PIN is available and how to set one up.
If you travel internationally often or plan to withdraw cash from ATMs, setting up a PIN before you leave the country is the safest approach. You won't be stuck at an ATM abroad or unable to pay at a store that requires one.
Frequently Asked Questions
Can I use my credit card at a store without a PIN if the terminal asks for one?
It depends on the terminal and the merchant. Some terminals will let you sign instead, while others will only accept a PIN. If the terminal won't accept your card, ask the merchant if they have another payment method available, such as a different card reader or contactless payment.
Do I need a PIN to use my credit card online?
No. Online purchases use your card number, expiration date, and CVV code instead. A PIN is only needed for in-person ATM withdrawals and some in-person store purchases outside the U.S.
What's the difference between a credit card PIN and a debit card PIN?
Both are four-digit codes, but they protect different things. A debit card PIN protects your bank account because the money is yours. A credit card PIN protects the card issuer's money (your credit line). You can set a credit card PIN yourself; a debit card PIN is usually required from the start.
If I set a PIN, do I have to use it for all my credit card purchases?
No. Having a PIN doesn't change how you use your card at stores or online. You'll only need to enter it at ATMs or at merchants (usually overseas) that specifically require it. Regular purchases still work with a signature or contactless tap.
Can I change my credit card PIN whenever I want?
Yes. You can reset your PIN through your online account or by calling customer service anytime. There's no limit to how often you can change it, and there's no fee.
