To report a lost credit card, call the number on the back of any other card from the same bank or on your monthly statement, or open your bank’s mobile app and use the “report lost or stolen” option in the card settings. Do it as soon as you notice the card is gone. Federal law caps your personal liability for unauthorized charges at $50, and Visa and Mastercard both go further with zero-liability policies that usually eliminate even that amount.1Federal Trade Commission. Lost or Stolen Credit, ATM, and Debit Cards The urgency is practical rather than legal: every hour the card is out there is another charge you may have to dispute later.
Call, Tap, or Log In
Three channels work, and any of them stops new charges immediately.
By phone, the issuer’s number appears on your monthly statement, on the back of any other card from the same bank, or on the issuer’s website.2Federal Trade Commission (FTC). Lost or Stolen Credit, ATM, and Debit Cards Expect an automated menu before a representative picks up. The agent will verify your identity, lock the card, and give you a confirmation number. Write that number down with the date and time of the call. That timestamp is your proof of when you reported, and it decides which charges fall on which side of the notification line.
Most banking apps have a “report lost or stolen” option inside the card or account settings, which flags the account for the fraud team instantly. Online banking portals do the same thing and create a timestamped record automatically. Either digital channel saves you the phone menu.
What to Have Ready
Before you dial or log in, pull together:
- Your full name and the billing address on the account
- The last four digits of your Social Security number, or whatever identity check your issuer uses
- The approximate date and time you last had the card
- Your most recent authorized purchase, so the fraud team can draw a line between your charges and anyone else’s
The more specific you are about when the card went missing, the easier it is for the issuer to sort real transactions from fraudulent ones.
Follow Up in Writing
Call first, then write. The FTC specifically recommends a written follow-up, and it’s the step most cardholders skip.1Federal Trade Commission. Lost or Stolen Credit, ATM, and Debit Cards In the letter, give your account number, the date and time you noticed the card was missing, and when you first reported it by phone. Keep a copy along with your notes from the call.
Send the letter to the address your issuer lists for billing disputes or inquiries, not the payment address. These are almost always different and both appear on your monthly statement, on the issuer’s website, or in your card agreement.3Federal Trade Commission. Sample Letter for Disputing Credit and Debit Card Charges The paper trail protects you if the phone report never makes it into the issuer’s system, or if you later need to prove exactly when you provided notice.
What You’ll Actually Owe
The Truth in Lending Act caps your personal liability for unauthorized credit card charges at $50.4Office of the Law Revision Counsel. 15 USC 1643 – Liability of Holder of Credit Card That $50 covers every unauthorized charge made before you notified the issuer, no matter how long you waited. After notification, your liability for any further unauthorized use drops to zero by statute.1Federal Trade Commission. Lost or Stolen Credit, ATM, and Debit Cards
If the physical card never left your possession and only the number was stolen, through a data breach or a skimmer, you owe nothing at all under the statute. The law treats that situation differently from a lost card.4Office of the Law Revision Counsel. 15 USC 1643 – Liability of Holder of Credit Card
In practice, the $50 cap rarely matters. Visa’s zero-liability policy covers both credit and debit transactions and requires issuers to replace stolen funds within five business days of notification.5Visa. Visa Zero Liability Policy Mastercard’s policy covers in-store, online, phone, and mobile transactions.6Mastercard. Mastercard Zero Liability Protection Policy Both policies require that you used reasonable care in protecting the card and reported the loss promptly. Both exclude commercial cards and anonymous prepaid cards like gift cards. A provisional refund can be reversed if the issuer’s investigation finds gross negligence or determines the claim itself is fraudulent.
One boundary worth knowing: if what you lost is a debit card, these rules do not apply. Debit cards fall under the Electronic Fund Transfer Act, where liability can climb to $500 after two business days and becomes potentially unlimited after 60 days.7GovInfo. 15 USC 1693g – Consumer Liability The networks’ zero-liability policies cover their branded debit cards too, but that protection is a corporate policy rather than a statutory guarantee.
What Happens to Your Account Next
Once you report, the issuer deactivates the old card number so nothing new goes through.1Federal Trade Commission. Lost or Stolen Credit, ATM, and Debit Cards A replacement with a new number ships out, typically in five to seven business days, and some issuers offer expedited shipping. Charges you legitimately authorized before the loss generally settle normally unless you flag them as fraudulent.
Reporting the card does not affect your credit score. The underlying account stays open with the same history, age, and payment record. Only the card number changes.
Recurring Payments
Any subscription or automatic payment tied to the old number will fail once the card is deactivated. You’ll need to update your payment information with each merchant after the replacement arrives. Visa and Mastercard both operate automatic billing updater services that share your new card details with participating merchants, so some charges may keep working seamlessly while others decline.8Mastercard Developers. Automatic Billing Updater You can’t predict which merchants participate, so review your recurring charges carefully during the first billing cycle after the replacement to catch anything that fell through.
Digital Wallets
If the lost card was in Apple Pay, Google Pay, or a similar wallet, what happens depends on your issuer. Some push new card information to the wallet automatically through tokenization. Others require you to re-add the card by hand. The cleanest approach is to remove the old card from the wallet yourself and add the replacement fresh when it arrives.
If You Lose the Card Overseas
Losing a card abroad adds urgency because you may be relying on it for hotels and meals. Visa cardholders can call collect at +1-303-967-1096 from any country where a local toll-free number isn’t available.9Visa Global Customer Assistance Services. Visa Global Customer Assistance Services Toll-free Numbers Mastercard and other networks maintain similar global assistance lines. Your issuer can often arrange an emergency replacement or a cash advance wired to a local bank, though availability and fees vary. Before any international trip, save your issuer’s international number in your phone; tracking it down from a foreign hotel with no card and spotty internet is miserable and entirely preventable.
The 60-Day Window to Dispute Specific Charges
Reporting the card as lost is separate from disputing individual unauthorized charges. The Fair Credit Billing Act gives you 60 days from the date your issuer sends the statement containing a suspicious charge to submit a written dispute.10Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
Send the written notice to the billing dispute address (again, not the payment address) with your name, account number, the charge you’re disputing, the dollar amount, and why you believe it’s an error.11Consumer Financial Protection Bureau. Billing Error Resolution – 1026.13 While the issuer investigates, it can’t try to collect the disputed amount or report it as delinquent. Missing the 60-day window doesn’t erase every right you have, but it seriously weakens your legal position, so review every statement carefully in the weeks after a loss, even if you reported the card the same day.
When to Add a Fraud Alert or Freeze
If the card was stolen alongside other identifying information, such as a wallet with your driver’s license or Social Security card, consider taking two more steps.
A fraud alert tells lenders to verify your identity before opening new credit in your name. Contact any one of the three major credit bureaus, Equifax, Experian, or TransUnion, and that bureau is required to notify the other two. An initial fraud alert lasts one year and costs nothing.12Federal Trade Commission. Credit Freezes and Fraud Alerts
A credit freeze goes further by blocking new credit applications entirely until you lift it. Freezes are free and stay in place indefinitely, and you can temporarily lift one when you need to apply for new credit yourself.12Federal Trade Commission. Credit Freezes and Fraud Alerts
If accounts you don’t recognize are already appearing in your name, file a report at IdentityTheft.gov. The site generates a personalized recovery plan, pre-fills dispute letters, and tracks each step.13Federal Trade Commission. IdentityTheft.gov Some issuers and credit bureaus require an FTC report before granting an extended fraud alert, which lasts seven years.
