Most credit cards in the United States do not require a PIN for everyday purchases
A PIN (personal identification number) is not standard for credit card transactions at stores, online, or over the phone. You sign a receipt or enter your card details instead. However, some situations do require a PIN: cash advances at ATMs, certain international transactions, and some chip-enabled terminals that prompt for one. The rules vary by card issuer, merchant type, and where you're using the card.
The reason most credit cards skip the PIN is historical. Credit card networks built their system around signatures and card verification codes printed on the back. Debit cards, by contrast, almost always require a PIN because they draw directly from your bank account and need that extra security layer. Credit cards shifted that risk to the issuer, not you, which is why the industry never made PINs mandatory.
Key Takeaways
- Credit cards do not require a PIN for in-store purchases, online shopping, or phone orders in the United States.
- A PIN is required when you withdraw cash from an ATM using your credit card, and you must set one up in advance through your card issuer.
- Some merchants or terminals may ask for a PIN even for regular purchases, but you can usually choose to sign instead.
- International transactions sometimes require a PIN, especially in countries where chip-and-PIN is the standard payment method.
- If your card issuer offers a PIN option, setting one up adds a layer of security for transactions where you cannot use your card physically.
When you need a PIN for a credit card
The most common scenario is a cash advance. If you use your credit card at an ATM to withdraw cash, you will need a PIN. This is not the same as using a debit card — the cash comes from your credit line, not your checking account, and you pay interest on it when ready. Before you can do this, you must set up a PIN with your card issuer, usually through their website, mobile app, or by calling the customer service number on the back of your card.
International travel is another situation where a PIN may be required. Many countries outside the United States, particularly in Europe and Asia, use chip-and-PIN as their standard payment method. When you insert your card into a terminal abroad, it may prompt you for a PIN instead of asking for a signature. If you do not have one set up, you may not be able to complete the transaction. Some merchants will accept a signature as an alternative, but not all.
Certain merchants in the United States also request a PIN for regular purchases, though this is less common. Gas pumps, some self-checkout systems, and certain retail terminals may prompt for one. You typically have the option to sign instead, but the terminal may not always make that choice obvious.
How to set up a PIN on your credit card
The process differs slightly by card issuer, but most follow the same basic steps. Log into your card's online account or mobile app and look for a section labeled "Card Settings," "Security," or "PIN Management." Select the option to set or change your PIN. You will be asked to create a four-digit number — choose something you can remember but that is not obvious, like your birth year or a sequence of repeating numbers.
If you cannot find the PIN option online, call the customer service number on the back of your card. A representative can walk you through setting one up over the phone. Some issuers will mail you a temporary PIN and ask you to change it on first use. Write down where you set it and when, in case you need to reset it later — most issuers allow you to change your PIN as often as you want.
If you forget your PIN, contact your card issuer directly. They can reset it and either send you a new one by mail or let you create a new one when ready through their app or website. This process usually takes a few minutes to a few hours, depending on the issuer.
Credit cards versus debit cards: why the difference
Debit cards require a PIN for nearly every transaction because the money comes directly from your bank account. The PIN protects your actual cash. If someone steals your debit card and knows your PIN, they can drain your account. Banks use the PIN as the primary security measure.
Credit cards work differently. You are borrowing money from the card issuer, not spending your own. If someone uses your card fraudulently, the issuer absorbs the loss, not you. Federal law limits your liability to $50 for unauthorized credit card charges, and most issuers waive that entirely if you report the fraud promptly. Because the issuer bears the risk, they rely on other security methods: signatures, card verification codes, address verification, and fraud monitoring systems. A PIN is optional, not required.
What happens if a terminal asks for a PIN and you do not have one
If a U.S. merchant's terminal prompts for a PIN and you have not set one up, you have options. Many terminals will allow you to press "Cancel" or "No PIN" and proceed to sign instead. If the terminal does not offer that choice, you can ask the cashier if they can process it as a signature transaction manually, or you can use a different payment method.
Abroad, the situation is less flexible. If a terminal requires a PIN and you do not have one, you may not be able to complete the transaction at all. Some merchants will accept a signature, but many will not. This is why setting up a PIN before international travel is worth doing, even if you never use it domestically.
Security considerations for credit card PINs
A PIN adds a layer of security, but only in specific situations. For in-store purchases where you hand your card to a cashier or insert it into a terminal, a signature or chip verification is the standard. A PIN does not protect you there. A PIN mainly protects you when you are using an ATM or in a country where the terminal requires one.
If you do set a PIN, treat it like you would a debit card PIN: do not write it down, do not use a number someone could guess, and do not share it. If you suspect someone knows your PIN, contact your card issuer and ask them to reset it. The same fraud protections explore to credit cards whether you have a PIN or not, so a compromised PIN is not a financial emergency — but it is worth fixing quickly.
Frequently Asked Questions
Do I have to set up a PIN on my credit card?
No. A PIN is optional for most credit cards in the United States. You can use your card for years without ever setting one up. However, if you plan to withdraw cash from an ATM or travel internationally, setting one up beforehand is practical.
Can I use my credit card at an ATM without a PIN?
No. ATMs require a PIN to withdraw cash, whether you are using a debit card or a credit card. If you do not have a PIN set up, you cannot complete the transaction. You must set one up with your card issuer first.
What if I forget my PIN?
Contact your card issuer's customer service line. They can reset your PIN and either send you a new one by mail or allow you to create one when ready through your online account or app. The process usually takes a few minutes to a few hours.
Is a credit card PIN the same as my debit card PIN?
No. Each card has its own PIN. If you have both a credit card and a debit card from the same bank, you can set different PINs for each one, or you can make them the same — the choice is yours. Most people keep them separate for security.
Do I need a PIN to use my credit card online or over the phone?
No. Online and phone purchases use your card number, expiration date, and the three-digit security code on the back. A PIN is not part of that process. PINs are only for in-person transactions at ATMs or terminals, and for some international purchases.
