Most credit cards don't require a PIN in the United States, but some situations demand one
In the U.S., credit cards typically work without a personal identification number (PIN). You sign a receipt or use contactless payment instead. However, a PIN becomes necessary in specific situations: when you withdraw cash from an ATM using your credit card, when you use your card at a terminal outside the U.S., or when your card issuer requires one for online or phone purchases. Understanding when a PIN is required — and when it isn't — helps you avoid declined transactions and protects your account.
The reason most U.S. credit cards skip the PIN is historical. Credit card networks built their system around the signature as proof of authorization. Debit cards, by contrast, almost always require a PIN because they draw directly from your bank account. Credit cards sit between you and the issuer, which is why the liability rules differ and the authentication method differs too.
Key Takeaways
- Credit card PINs are required for ATM cash withdrawals, international transactions at certain terminals, and some online or phone purchases, but not for everyday in-store purchases.
- You set your own PIN through your card issuer's website, mobile app, or by calling the customer service number on the back of your card.
- A PIN is not the same as your CVV (the three-digit security code on the back); you need both for different purposes.
- If you forget your PIN, you can reset it when ready through your issuer's app or website without calling customer service.
- Some credit cards don't offer PIN functionality at all, particularly older cards or those from smaller issuers, so check with your bank if you need one.
When you absolutely need a PIN with your credit card
ATM cash withdrawals are the most common reason you'll need a PIN. When you insert your credit card into an ATM to get cash, the machine requires a PIN to verify you're the cardholder. This is true whether you're using your own bank's ATM or a third-party machine. Without the PIN, the transaction will be declined.
International transactions at certain terminals also require a PIN. Many countries outside the U.S. — particularly in Europe, Asia, and Latin America — use chip-and-PIN technology as their standard authentication method. If you travel abroad and use your credit card at a gas pump, toll booth, or unattended kiosk, you may be prompted for a PIN. Some stores will also ask for a PIN at the register instead of a signature. If your card doesn't have a PIN set, the transaction may fail.
Online and phone purchases sometimes require a PIN, though this is less common. Some card issuers use a PIN as an additional security layer for high-risk transactions, such as large purchases or transactions from unfamiliar locations. Your issuer may text or email you asking for your PIN to complete the purchase.
How to set up a PIN for your credit card
Most card issuers let you create or change your PIN through their mobile app or website. Log into your account, look for a section labeled "Card Settings," "Security," or "PIN Management," and follow the prompts. You'll typically choose a four-digit number that you can remember but others cannot easily guess. Avoid birthdays, sequential numbers (1234), or repeated digits (1111).
If your issuer doesn't offer online PIN setup, call the customer service number on the back of your card. A representative can walk you through the process over the phone. Some issuers mail a temporary PIN with your new card; you can then change it to something you prefer.
The process usually takes seconds and becomes active when ready. You don't need to wait for a new card or confirmation letter.
PIN versus CVV: what's the difference
A PIN is a four-digit number you create and memorize. You enter it at an ATM or at a terminal when prompted. It proves you have physical possession of the card and know the secret code.
A CVV (Card Verification Value) is a three- or four-digit code printed on the back of your card. You provide it when making online or phone purchases to prove you have the physical card in hand. You do not memorize it; you read it from the card each time.
Both protect your account, but they serve different purposes. A PIN protects in-person and ATM transactions. A CVV protects remote transactions. You need both if you plan to use your card internationally and online.
What happens if you forget your PIN
Forgetting your PIN is not an emergency. You can reset it when ready through your card issuer's app or website using the same "Card Settings" or "PIN Management" section where you created it. The new PIN is active right away.
If you're at an ATM and can't remember your PIN, you cannot retrieve it on the spot. You'll need to reset it through your issuer's app or website before your next ATM visit, or call customer service to do it over the phone. Some issuers can reset your PIN during the call and tell you the temporary one, which you can then change online.
If you enter the wrong PIN three times in a row at an ATM, the machine will usually lock you out temporarily to prevent fraud. Wait a few minutes and try again, or reset your PIN through your issuer's app.
Do all credit cards have PIN capability
Not every credit card offers PIN functionality. Older cards or cards from smaller regional banks may not have this feature built in. If you need a PIN and your card doesn't support one, contact your issuer to ask whether they can enable it or whether you need to request a replacement card with PIN capability.
Most major issuers — Chase, Bank of America, American Express, Discover, Capital One, and Citi — support PIN setup on their credit cards. If you're unsure whether your card has PIN capability, check your issuer's website or call the number on the back of your card.
PIN security: protecting your number
Your PIN is as sensitive as your password. Never write it down, share it with anyone, or use a PIN that's straightforward to guess. When you enter your PIN at an ATM or terminal, shield the keypad with your hand so cameras or bystanders cannot see the numbers.
Your card issuer will never ask you for your PIN via email, text, or phone call. If someone contacts you claiming to need your PIN, it's a scam. Hang up or delete the message and contact your issuer directly using the number on your card.
If you believe your PIN has been compromised, reset it when ready through your issuer's app or website. You can change it as many times as you want at no cost.
Frequently Asked Questions
Can I use my credit card at a U.S. store without a PIN?
Yes. Most U.S. stores don't require a PIN for credit card purchases. You'll either sign a receipt or use contactless payment (tap or mobile wallet). A PIN is only needed at ATMs, some international terminals, and occasionally for high-risk online or phone purchases.
What if I'm traveling abroad and don't have a PIN set?
Set your PIN before you leave. Many countries use chip-and-PIN terminals, and without a PIN your card may be declined at gas pumps, toll booths, and unattended kiosks. You can set it through your issuer's app in minutes. Some issuers also let you use a signature instead of a PIN in certain countries, but having a PIN is safer and more reliable.
Is my PIN the same as my online banking password?
No. Your PIN is separate from your online banking password. Your PIN is used at ATMs and in-person terminals. Your password is used to log into your account online. You set and manage both independently.
Can someone use my credit card if they know my PIN?
They can attempt to use it at an ATM or terminal, but they still need the physical card. If your card is lost or stolen, contact your issuer when ready to freeze or cancel it. You're not liable for fraudulent charges made after you report the card missing, even if the thief knows your PIN.
Do I need a PIN for contactless payments?
No. Contactless payments (tapping your card or phone) don't require a PIN for small purchases. However, some terminals may ask for a PIN if the purchase amount is high or if the terminal's security settings require it. This varies by merchant and issuer.
