Most credit cards in the U.S. don't require a PIN for everyday purchases, but you may need one for cash advances or 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 handle PINs differently. With a debit card, you almost always need a PIN to withdraw cash or make purchases at the point of sale. With a credit card, a PIN is optional in most situations — you can sign a receipt or use contactless payment instead.
Whether you need a PIN depends on how you're using the card and where you're using it. A PIN becomes necessary when the card reader can't process a signature, when you're getting cash from an ATM, or when you're in a country where chip-and-PIN is the standard payment method. Understanding when a PIN is required saves you from being declined at checkout or unable to access cash when you need it.
Key Takeaways
- U.S. credit cards typically use signature verification instead of PINs, so you can make most purchases without entering a code.
- You will need a PIN if you want to withdraw cash from an ATM using your credit card, since that counts as a cash advance.
- Many countries outside the U.S. require a PIN for all credit card transactions, even small purchases, so set one before traveling internationally.
- Contactless payment (tapping your card) works without a PIN or signature for purchases under a certain amount, usually $25 to $100.
- Your card issuer can set up a PIN for you by phone or through your online account, and you can change it anytime.
When a PIN is required for credit cards
You need a PIN when you withdraw cash from an ATM using your credit card. This is treated as a cash advance, not a regular purchase, and the ATM requires a PIN to confirm your identity. Cash advances typically carry a higher interest rate and an upfront fee, so check your card's terms before using this feature.
A PIN is also required in most countries outside the U.S., even for small purchases. Europe, Canada, Australia, and much of Asia use chip-and-PIN as the standard payment method. If you travel internationally and your card doesn't have a PIN set, you may be unable to complete transactions at unattended machines (like parking meters or train ticket kiosks) or at merchants who don't accept signature-based payments. Some in-person retailers may also refuse a card without a PIN.
Certain U.S. merchants — typically gas stations, parking garages, and automated kiosks — may request a PIN even though it's not standard. If the card reader can't process a signature (because the screen is broken or the merchant doesn't have the capability), you may be asked for a PIN as a backup.
When you don't need a PIN in the U.S.
For regular in-store purchases at most U.S. retailers, you can sign the receipt or use contactless payment instead of entering a PIN. Contactless payment — tapping or waving your card near the reader — works without a PIN or signature for transactions under a set limit, usually $25 to $100 depending on your card issuer and the merchant.
Online purchases never require a PIN. You provide your card number, expiration date, and CVV (the three-digit security code on the back) instead. Phone purchases work the same way — the merchant takes your card details over the phone without needing a PIN.
Mail-order purchases also don't use a PIN. You mail your card details or provide them by phone, and the merchant processes the transaction without any code.
How to set up or change your credit card PIN
If your card issuer allows PINs, you can set one up through your online account or by calling the customer service number on the back of your card. Most issuers let you choose your own four-digit code, though some may assign one and let you change it later. The process usually takes a few minutes and goes into effect when ready or within 24 hours.
If you forget your PIN, call your card issuer and verify your identity (usually by providing your Social Security number and other account details). They can reset it or send you a temporary PIN by mail. If you want to change your PIN after it's set, you can do so through your online account or by phone — you don't need to contact the issuer in person.
Before traveling internationally, set up a PIN even if you don't plan to use cash advances. Many overseas merchants and ATMs won't process your card without one, and setting it up at home is faster than trying to do it from abroad.
PIN security and fraud protection
A PIN adds a layer of security because it proves you have physical possession of the card. If someone steals your card number but doesn't know your PIN, they can't withdraw cash or make purchases in countries that require a PIN. However, a PIN doesn't protect you from online fraud — online transactions don't use a PIN, so a thief with your card number and CVV can still make purchases online.
Never share your PIN with anyone, including bank employees or customer service representatives. Your issuer will never ask for your PIN over the phone or by email. If someone claims to be from your bank and asks for your PIN, hang up and call the number on the back of your card to verify.
If you enter your PIN incorrectly multiple times, the card reader may lock you out temporarily as a fraud prevention measure. Wait a few minutes and try again, or contact your issuer if the card remains blocked.
PIN requirements by card type and issuer
Not all credit card issuers offer PIN functionality. Visa and Mastercard credit cards in the U.S. typically don't require PINs for everyday use, but most issuers will set one up if you request it. American Express and Discover cards have similar policies — PINs are optional and mainly useful for international travel or cash advances.
Debit cards, by contrast, almost always require a PIN. When you use a debit card, you're accessing your bank account directly, so the PIN is a security requirement rather than an option. Credit cards are different because the card issuer (not your bank account) is responsible for the charge, so signature or contactless payment is sufficient.
Some premium or business credit cards may have different PIN policies. Check your card's terms or call your issuer to confirm whether a PIN is available and what it covers.
What to do if your card is declined without a PIN
If a merchant asks for a PIN and you don't have one set up, ask if they accept signature or contactless payment instead. Most U.S. merchants will accept one of these alternatives. If the card reader is broken and can't process a signature, the merchant may ask you to try a different payment method or come back later.
If you're traveling internationally and your card is declined because it doesn't have a PIN, contact your issuer when ready. They can set one up over the phone, though it may take 24 hours to set up. In the meantime, look for ATMs that accept your card (they may allow you to withdraw cash without a PIN, depending on the country) or use a different payment method.
If you're at an ATM and your card is declined, double-check that you're using a credit card and not a debit card — some ATMs don't accept credit cards for cash advances. If the ATM still declines you, try a different ATM or contact your issuer to confirm your PIN is active.
Frequently Asked Questions
Do I need a PIN to use my credit card at the grocery store?
No. You can sign the receipt, use contactless payment, or provide your card number online. A PIN is not required for regular purchases at U.S. retailers. Some older card readers may ask for a PIN if they can't process a signature, but this is uncommon.
What happens if I forget my PIN while traveling?
Call your card issuer's customer service number (usually on the back of your card or your statement). They can reset your PIN or provide a temporary one. Keep the issuer's international customer service number in your phone before you travel, since calling from abroad may have different dialing instructions.
Can I use my credit card at an ATM without a PIN?
No. ATMs require a PIN to withdraw cash because it's a cash advance, not a regular purchase. If you don't have a PIN set up, you won't be able to use the ATM. Set one up before you travel or need cash.
Is a PIN the same as a CVV?
No. A PIN is a four-digit code you enter at a card reader or ATM to prove you own the card. A CVV is a three-digit security code printed on the back of your card and used for online or phone purchases. You need both for different types of transactions.
Do I need a PIN if I use contactless payment?
No. Contactless payment (tapping your card) works without a PIN or signature for purchases under your issuer's limit, usually $25 to $100. For larger purchases, you may be asked to sign or enter a PIN, depending on the merchant.
