For everyday purchases in the United States, a credit card does not need a PIN — the chip in the card handles authentication, and most terminals ask for nothing more than a tap or an insert. You will need a PIN in two situations: withdrawing cash from an ATM, and paying at certain unattended machines when traveling abroad.
When You Don’t Need a PIN
At a U.S. store, restaurant, or gas pump, the terminal almost never prompts for a PIN. The EMV chip generates a unique, one-time security code for each transaction, and the card network uses that cryptographic handshake to confirm the card is genuine.1EMVCo. EMV Contact Chip Signatures are no longer required either. Most cardholders in the U.S. can go years without setting up a PIN and never notice.
The reason credit cards work differently from debit cards at checkout is which federal law applies. Debit cards fall under the Electronic Fund Transfer Act and Regulation E, which cover ATM withdrawals and point-of-sale debit transactions.2National Credit Union Administration. Electronic Funds Transfer (EFT) and Regulation E Credit cards fall under the Truth in Lending Act and Regulation Z, which do not require PIN entry at the register.
When a PIN Is Required
ATM Cash Advances
Any time you use a credit card at an ATM to withdraw cash, you have to enter a PIN. That rule doesn’t bend, and it applies in every country. The machine will not dispense money without the code.
Unattended Terminals Abroad
Outside the U.S., chip-and-PIN is the norm. At a staffed register overseas — a hotel, restaurant, or department store — the cashier can usually fall back to a signature when a U.S. card doesn’t prompt for a PIN. Unattended machines are the problem. Train-ticket kiosks, highway toll booths, parking meters, and vending machines have no way to accept a signature, and they will decline your card if you can’t enter a PIN.
Some countries also use six-digit PINs rather than four. Travelers have reported trouble using four-digit PINs at certain ATMs in parts of Asia, so check with your issuer about your destination before you go.
What a Cash Advance Actually Costs
Before you enter your PIN at an ATM, know what you’re being charged. A credit card cash advance is one of the most expensive ways to get money:
- An upfront fee of roughly 3% to 5% of the amount withdrawn. On a $500 advance, that’s $15 to $25 before you leave the machine.
- A separate, higher APR for cash advances. At major banks the cash advance rate often runs around 30%, compared with about 22% for regular purchases.
- No grace period. Interest starts accruing the moment the cash is dispensed, unlike purchases where paying in full each month avoids interest entirely.3Consumer Financial Protection Bureau. What Is a Grace Period for a Credit Card
- An ATM operator surcharge on top, often $2 to $5.
Your issuer has to disclose the cash advance APR and fees when you open the account and on every statement.4eCFR. 12 CFR Part 226 – Truth in Lending (Regulation Z) The exact figures are in the pricing table with your cardholder agreement. Treat a cash advance as a last resort.
How to Set Up or Change Your PIN
Some issuers include a PIN with your new card; many don’t. To set one up or change it:
- Log in to your issuer’s website or mobile app and look under card settings or security. Some issuers let you set or change the PIN instantly.
- Call the customer service number on the back of the card. An automated system or a representative will verify your identity and walk you through it.
- At an ATM operated by your issuer, insert the card and follow the on-screen prompts, if that option is available.
Available methods vary by bank. Issuers are allowed to send a PIN to an existing cardholder without a specific request, provided the PIN alone doesn’t unlock the credit — it has to be used together with the physical card.5Consumer Financial Protection Bureau. 1026.12 Special Credit Card Provisions
If you’re heading overseas, set the PIN well before you leave. Some issuers mail PINs, and delivery can take a week or more. Discovering the gap at a foreign train station is a bad time to find out.
If You Enter the Wrong PIN
Three wrong entries in a row at an ATM or terminal will usually trigger a temporary lockout. The block may lift automatically after 24 hours, or you may need to call your issuer to unfreeze the card — policies differ by bank. Don’t keep guessing. Repeated failed attempts can also flag the account for potential fraud, which extends the hold. Contact your issuer through the app, website, or customer service line to reset the code.
Does a PIN Change Your Fraud Liability?
If a thief uses your credit card with your PIN, federal law still caps your liability at $50, as long as you notify the issuer after finding the unauthorized charges.6Office of the Law Revision Counsel. 15 U.S. Code 1643 – Liability of Holder of Credit Card For that cap to apply, the issuer must have given you a way to report the loss and a method to identify authorized users, such as a PIN or signature.5Consumer Financial Protection Bureau. 1026.12 Special Credit Card Provisions Most major issuers go further with zero-liability policies, so in practice you usually owe nothing on fraudulent charges. If the thief uses only your card number and expiration date, with no PIN or physical card, you have no statutory liability at all. Report a lost or stolen card as soon as you notice, and you’re not responsible for anything charged afterward.
