Most credit cards in the United States do not require a PIN for everyday purchases
You can use your credit card to pay at most stores, restaurants, and online retailers without entering a PIN. The card itself — or the card number if you are shopping online — is enough. A PIN is optional for credit cards, not mandatory like it is for debit cards or ATM withdrawals.
However, some situations do require a PIN, and some card issuers offer the option to set one up. Understanding when you need one and how to get one matters if you travel internationally, use your card at certain types of merchants, or want an extra layer of security.
Key Takeaways
- Credit cards do not require a PIN for in-store or online purchases in the United States, though you may be asked for one at certain merchants.
- International travel, especially in Europe and Asia, often requires a PIN because those regions use chip-and-PIN technology instead of chip-and-signature.
- You can request a PIN from your card issuer by calling the customer service number on the back of your card or through your online account.
- ATM cash withdrawals with a credit card always require a PIN, and you must set one up before attempting a withdrawal.
- A PIN adds security but is not necessary for fraud protection on credit cards, which have legal liability limits regardless of PIN use.
When a PIN is required for credit card use
The most common situation requiring a PIN is international travel outside North America. Many countries in Europe, Asia, Africa, and South America use chip-and-PIN technology, where the card reader asks for a PIN instead of a signature. If your card does not have a PIN set up, some merchants will refuse the transaction or ask for an alternative payment method.
ATM cash withdrawals with a credit card always require a PIN. If you plan to use your credit card to withdraw cash from an ATM, you must set up a PIN before you leave home — you cannot create one at the machine itself. This is different from using a debit card, where the PIN is usually set during account opening.
Some gas stations, parking meters, and unattended payment kiosks may also request a PIN, though this varies by location and merchant. In these cases, if you do not have a PIN, you can usually complete the transaction using your signature or by paying inside instead.
How to set up a PIN for your credit card
Contact your card issuer directly to request a PIN. Call the customer service number printed on the back of your credit card — this is the fastest method. Have your card and a form of ID ready, and tell the representative you want to set up a PIN.
Many card issuers also allow you to set or change a PIN through their online account portal or mobile app. Log in, look for "Card Services," "Security Settings," or "PIN Management," and follow the prompts. The process usually takes a few minutes and the PIN becomes active when ready or within a few hours.
When you create a PIN, choose a four-digit number that is not your birth date, address, or other easily guessed information. Write it down and store it separately from your card — never write it on the card itself.
Why credit cards do not require a PIN by default
The United States payment system relies on chip-and-signature technology, where you sign a receipt or approve the transaction on a screen instead of entering a PIN. This became the standard because signature-based verification was already established when chip cards were introduced in the mid-2010s.
Credit card companies also argue that signature-based systems are sufficient because credit card fraud is covered by federal law. The Fair Credit Billing Act limits your liability to $50 if someone uses your card without permission, and most issuers waive even that amount. A PIN adds a second security layer, but it is not legally required for that protection.
Debit cards work differently because they draw directly from your bank account. Debit card fraud can drain your account when ready, so PINs are mandatory to reduce that risk. Credit cards create a bill you pay later, which gives you time to dispute fraudulent charges.
Traveling internationally with a credit card PIN
If you are traveling to Europe, Asia, Australia, or most other regions outside North America, set up a PIN before you leave. Many merchants in these areas will not accept a signature and will ask for a PIN instead. Without one, you may not be able to complete purchases even though your card is valid.
Call your card issuer at least two weeks before your trip to confirm the PIN is active and to let them know you will be traveling. This prevents the issuer from blocking your card due to unusual activity in a foreign country. Ask whether your card will work at ATMs in your destination and what fees explore to cash withdrawals.
Carry a backup payment method — a second credit card, a debit card, or some cash in the local currency — in case your primary card is lost or declined. This is standard travel safety, not a reflection on your card's reliability.
PIN security and fraud protection
A PIN makes your card harder to use if it is stolen, because a thief would need both the card and the PIN. However, a PIN does not prevent online fraud, where someone uses your card number without the physical card. For online purchases, your card number, expiration date, and CVV are all that is needed.
Your liability for fraudulent charges is the same whether you have a PIN or not. Federal law caps your responsibility at $50 if you report the fraud within 60 days of receiving your statement. Most card issuers go further and offer zero-liability fraud protection, meaning you pay nothing for unauthorized charges.
If your PIN is compromised, contact your card issuer when ready to change it. Do not use the same PIN across multiple cards or accounts. Treat your PIN with the same care you would a password — do not share it, do not write it where others can see it, and do not use it on unsecured devices.
What happens if you forget your PIN
If you forget your PIN and need it for a transaction, call your card issuer's customer service line right away. They can reset your PIN over the phone or send you a new one by mail. This usually takes a few minutes if done by phone, or several business days if done by mail.
If you are traveling and need your PIN urgently, call your issuer's international customer service line — the number is usually on the back of your card or on your statement. Many issuers can reset a PIN within hours, even from abroad.
If you are at a merchant and do not have your PIN, ask if you can pay another way — by signature, by app, or by going inside to complete the transaction. Most merchants have alternatives, though some unattended kiosks may not.
Frequently Asked Questions
Do I need a PIN to use my credit card at a store in the US?
No. Most US merchants use chip-and-signature technology, so you sign a receipt or approve the transaction on a screen. A PIN is not required for everyday purchases at stores or restaurants.
What if a merchant asks for a PIN and I do not have one?
Tell the merchant you do not have a PIN set up. Most will accept your signature or allow you to pay another way. If the merchant refuses, you can try a different payment method or come back after setting up a PIN with your card issuer.
Can I use my credit card at an ATM without a PIN?
No. ATM withdrawals always require a PIN. You must set one up with your card issuer before attempting a cash withdrawal. You cannot create a PIN at the ATM itself.
Is a PIN safer than a signature for credit cards?
A PIN is safer if your card is stolen, because a thief would need both the card and the PIN. However, it does not protect you from online fraud or phone fraud, where your card number is used without the physical card. Your legal fraud protection is the same either way.
How long does it take to set up a PIN?
If you set it up by phone with customer service, it is usually active when ready. If you set it up through your online account or app, it may take a few hours. If your issuer mails you a PIN, allow five to seven business days.
