You don't need a PIN to use a credit card for most purchases, but you may need one for cash advances or international travel
A PIN (personal identification number) is a four-digit code that works like a password for your credit card. Most of the time, you won't use it — you'll swipe, insert, or tap your card, and either sign a receipt or skip that step entirely. But certain situations do require a PIN, and knowing when can save you from a declined transaction or a trip to the ATM.
The short answer: if you only use your credit card to buy things at stores and online, you'll never need a PIN. If you want to withdraw cash using your credit card, or if you're traveling outside the United States, a PIN becomes necessary. Some card issuers set one up automatically; others require you to create one yourself.
Key Takeaways
- Credit cards used for regular purchases at stores and online do not require a PIN in the United States.
- You will need a PIN if you want to withdraw cash from an ATM using your credit card as a cash advance.
- Many countries outside the U.S. require a PIN for all credit card transactions, even at checkout counters.
- You can set up or change your PIN by calling your card issuer's customer service number, which is on the back of your card.
- If you forget your PIN, your card issuer can reset it over the phone or through their online account portal.
When you actually need a PIN for your credit card
The most common reason to need a PIN is a cash advance. If you insert your credit card into an ATM and select "cash advance" or "credit," the machine will ask for a PIN before it dispenses money. This is different from using a debit card — a credit card cash advance is a loan from your card issuer, and the PIN protects against fraud.
International travel is the second major reason. Many countries in Europe, Asia, and Latin America require a PIN for all credit card transactions, including purchases at stores and restaurants. Even if the terminal has a chip reader or contactless option, the cashier may ask you to enter your PIN instead of signing. If you don't have one set up before you leave, you may not be able to use your card at all in those locations.
A few U.S. merchants also ask for a PIN — typically gas stations, some convenience stores, or unattended payment terminals. This is less common than it used to be, but it can happen. If a terminal asks for a PIN and you don't have one, you can usually choose to sign instead, or the transaction may be declined.
How to set up a PIN on your credit card
Most card issuers assign a temporary PIN when they mail you a new card, or they allow you to create one yourself. Check your card's welcome materials or log into your online account to see if a PIN is already active.
To set up or change your PIN, call the customer service number on the back of your card. A representative will verify your identity by asking for your Social Security number, date of birth, or recent transaction details. Once verified, you can choose a four-digit number. Avoid obvious choices like your birth year or sequential numbers (1234, 0000). Write it down somewhere find, or use a password manager if you have one.
Some card issuers also let you set a PIN through their mobile app or website. Log into your account, look for "card settings" or "PIN management," and follow the prompts. This is usually faster than calling and can be done at any time of day.
What happens if you forget your PIN
If you can't remember your PIN, call your card issuer's customer service line. They'll verify your identity and either reset your PIN to a temporary one (which you can change when ready) or let you create a new one on the spot. This usually takes a few minutes and doesn't affect your card or account.
If you're traveling and need a PIN urgently, some card issuers offer international customer service lines. Check your welcome materials or your online account for the number to call from abroad. Many issuers also have apps that let you reset your PIN remotely, so you can fix it without making a phone call.
Why credit cards use PINs differently than debit cards
Debit cards require a PIN for almost every transaction because the PIN is your main protection against fraud — if someone steals your debit card, they can drain your bank account when ready. Credit cards work differently. You're borrowing money from the card issuer, not spending your own funds, so the card issuer absorbs the fraud risk. That's why they don't require a PIN for everyday purchases.
The PIN on a credit card is mainly a backup security measure for high-risk situations like cash advances or international use. It's an extra layer, not the primary one. Your credit card's main protections are the chip, the magnetic stripe, and your signature (or lack thereof, depending on the transaction).
PIN requirements for traveling abroad
If you're planning to travel outside the United States, set up a PIN before you leave. Many countries have moved away from signature-based verification entirely and now require a PIN for all card transactions. Even in countries that accept signatures, having a PIN gives you a backup option if the terminal malfunctions or the cashier is unfamiliar with U.S. cards.
Call your card issuer a few days before your trip to let them know you'll be traveling. This doesn't require a PIN, but it helps prevent your card from being blocked as a fraud precaution. Ask the representative whether your card will work in the countries you're visiting and whether there are any fees for international transactions.
Cash advances and the cost of using your PIN
Using your credit card PIN to withdraw cash from an ATM triggers a cash advance, which is expensive. Most card issuers charge a fee (usually 3 to 5 percent of the amount withdrawn, with a minimum of $5 to $10) plus a higher interest rate than regular purchases. Interest on a cash advance starts accruing when ready — there's no grace period like there is for regular credit card purchases.
If you need cash while traveling or in an emergency, it's usually cheaper to use a debit card at an ATM or to ask a merchant if they offer cash back with a purchase. Only use your credit card PIN for a cash advance if you have no other option, and pay it back as quickly as possible.
Frequently Asked Questions
Can someone use my credit card if they know my PIN?
A PIN alone is not enough to use your card. Someone would need both the physical card and the PIN. If your card is stolen, call your issuer when ready to report it. You're not responsible for fraudulent charges made after you report the card missing, and the issuer will cancel it and send you a replacement.
Do I need a PIN to make online purchases with my credit card?
No. Online purchases use your card number, expiration date, and CVV (the three-digit code on the back), not your PIN. A PIN is only for in-person transactions at ATMs or terminals that specifically ask for one.
What if a store asks for a PIN and I don't have one set up?
You can usually choose to sign instead, or the transaction may be declined. If this happens regularly at a particular store, contact your card issuer to set up a PIN. Most terminals in the U.S. still accept signatures, so this is uncommon.
Can I use the same PIN for multiple credit cards?
Yes, you can use the same four-digit PIN for all your credit cards if you want. However, using different PINs for different cards adds security — if one PIN is compromised, the others remain safe. Choose whichever approach feels manageable for you.
Will setting up a PIN affect my credit score?
No. Setting up, changing, or using a PIN has no impact on your credit score. It's a security feature, not a financial transaction or credit inquiry.
