Credit cards don't require a PIN for most purchases, but you may need one in specific situations
In the United States, credit cards do not need a PIN for everyday shopping. You can swipe, insert, or tap your card at a store without entering a number. The transaction goes through with your signature (or no signature at all, depending on the merchant). However, a PIN becomes necessary when you use your credit card at an ATM to withdraw cash, or when you're making a purchase outside the US where chip-and-PIN is the standard payment method.
The reason for this difference comes down to how payment networks designed their systems. Visa and Mastercard built their US networks around signature verification and fraud monitoring rather than PIN protection. Debit cards, by contrast, almost always require a PIN because they draw directly from your bank account. Credit cards shift the liability to the card issuer, so the networks prioritized speed and convenience over PIN entry.
Whether you have a PIN on your credit card depends partly on your card issuer and partly on what you plan to use it for. Some issuers set one automatically; others let you create one if you need it. Knowing when you actually need a PIN—and how to get one if you don't have it—saves you from being stuck at an ATM or stranded abroad.
Key Takeaways
- Credit cards work without a PIN for in-store and online purchases in the United States, relying instead on signature or fraud detection.
- You will need a PIN if you want to withdraw cash from an ATM using your credit card, since ATMs require numeric entry.
- International travel often requires a PIN because many countries outside the US use chip-and-PIN as their standard payment method.
- You can request a PIN from your card issuer by calling the customer service number on the back of your card or logging into your online account.
- Having a PIN does not change how your card works for regular purchases—it only adds an option for ATM withdrawals and overseas use.
When you need a PIN for your credit card
The most common reason to need a PIN is ATM cash withdrawal. If you want to use your credit card to pull cash from an ATM, the machine will prompt you to enter a four-digit PIN. Without one, the transaction will be declined. This is different from a debit card withdrawal—the ATM treats a credit card cash advance as a loan, and the PIN is the security check.
International travel is the second major situation where a PIN matters. Many countries in Europe, Asia, and elsewhere have moved entirely to chip-and-PIN payment systems. When you insert your card into a payment terminal abroad, the machine may ask for a PIN instead of accepting a signature. If you don't have one set up, you may not be able to complete the purchase, even though your card is valid and you have available credit.
Some merchants in the US also request a PIN for large purchases or specific transaction types, though this is less common. Gas station pumps sometimes ask for a PIN as an extra verification step. In these cases, if you don't have a PIN, you can usually go inside and pay the attendant instead, or use a different payment method.
How to set up or change your credit card PIN
If your card issuer hasn't assigned you a PIN, or if you want to change the one you have, the process is straightforward. Call the customer service number on the back of your credit card. A representative will verify your identity by asking for your card number, date of birth, or other security information, then walk you through creating or resetting your PIN.
Many card issuers also let you set or change your PIN through their mobile app or website. Log into your account, look for a "Card Settings" or "Security" section, and find the option to manage your PIN. The exact steps vary by bank—Chase, American Express, Discover, and Citi all have slightly different interfaces—but the option is usually in account or card management.
If you forget your PIN, you don't need to panic. Call your issuer's customer service line and request a reset. They'll verify who you are and either tell you your current PIN or let you create a new one on the spot. Some issuers mail a new PIN to your address on file, which takes a few days, while others set it up when ready over the phone.
PIN versus signature: how credit card security actually works
In the US, credit cards rely on signature verification and fraud monitoring rather than PIN protection. When you sign a receipt, the merchant is supposed to check that your signature matches the one on the back of your card. In practice, most retailers don't look closely at signatures anymore. Instead, the card network and your bank monitor transactions for unusual patterns—a purchase in another state minutes after a local one, or a charge at 3 a.m., for example—and flag suspicious activity.
A PIN adds a second layer of security by requiring something you know (the number) rather than something you have (the card). If someone steals your card, they can't use it at an ATM or overseas without the PIN. For everyday US purchases, the card networks decided that the friction of entering a PIN slowed down checkout too much, so they built their security around other methods instead.
This is why your credit card liability is capped at $50 for unauthorized charges under federal law, and most issuers waive that entirely. The bank absorbs fraud losses, not you, so they have strong incentives to catch and stop fraudulent transactions quickly. A PIN helps, but it's not the main line of defense.
What happens if you don't have a PIN when you need one
At an ATM, if you don't have a PIN, the machine will straightforward decline your request and return your card. You won't be charged a fee for the failed attempt, though some ATM operators charge a small fee just for trying. You can then use a different payment method—a debit card, cash, or a check—to get the money you need.
Abroad, the situation is more limiting. If a store's payment terminal requires a PIN and you don't have one, you cannot complete the purchase with that card. You'll need to find an ATM that accepts your card (which usually does work, even without a PIN, because ATMs are designed to handle international cards), or use a different payment method. This is why travel guides recommend calling your issuer before you leave the country to confirm your PIN is active.
Online purchases never require a PIN, whether you're shopping in the US or internationally. You enter your card number, expiration date, and CVV (the three-digit security code on the back). A PIN is only needed for in-person transactions at physical terminals or ATMs.
Credit cards with built-in PIN options
Most major issuers—Visa, Mastercard, Discover, and American Express—allow you to set a PIN on any credit card, whether the card came with one or not. Some business credit cards and premium cards come with a PIN already activated. Secured credit cards, which are designed for people building credit, sometimes require a PIN as part of their security structure.
If you're planning to travel internationally or use your card at ATMs regularly, it's worth setting a PIN even if you don't have one yet. The process takes five minutes on the phone, and it gives you more flexibility without changing how your card works for regular purchases. You'll still be able to tap, swipe, or insert your card at checkout without entering anything.
Frequently Asked Questions
Can someone use my credit card without a PIN?
Yes, in the US, because credit cards don't require a PIN for most purchases. However, your card issuer monitors for fraud and will catch unauthorized charges. You're protected by federal law, which caps your liability at $50, and most banks waive that fee entirely. A PIN only protects you at ATMs and overseas.
Do I need a PIN to use my credit card at a store?
No. In the United States, stores accept credit cards with a signature, a tap, or no verification at all, depending on the amount and the merchant's system. A PIN is not required for in-store shopping. It's only needed at ATMs and in countries that use chip-and-PIN as their standard.
What's the difference between a credit card PIN and a debit card PIN?
Both are four-digit numbers, but they serve different purposes. A debit card PIN protects your bank account because the card draws money directly from it. A credit card PIN is optional for most US purchases and mainly protects you at ATMs and abroad. Debit cards almost always require a PIN; credit cards do not.
Will I be charged if I try to use my credit card at an ATM without a PIN?
The ATM will decline the transaction and return your card without charging you. However, some ATM operators charge a small fee just for attempting a withdrawal, regardless of whether it goes through. Check your card issuer's terms to see if they charge a fee for declined ATM attempts.
Can I use my credit card internationally without a PIN?
It depends on the country. In the US and some other places, you can use a signature or tap. In Europe, Asia, and most other regions, payment terminals require a PIN. Having one set up before you travel prevents you from being unable to pay at checkout. Online purchases never require a PIN, even internationally.
