Call your card issuer when ready — before you use the card again
The moment you realize your card is missing, call the customer service number on your bank's website or your statement. Do not call a number from a letter or email — go directly to the official website. Tell them your card is lost and ask them to freeze it right away. They will deactivate it so no one else can use it, even if they find it.
This call is the single most important step. Once the card is frozen, you are no longer responsible for charges made after that moment. Federal law caps your liability at $50 for unauthorized charges made before you report it lost, and $0 if you report it before any fraudulent charges post to your account.
Keep the date and time of your call and the name of the representative you spoke with. You may need this record later if a charge shows up that you did not make.
Key Takeaways
- Call your card issuer's official customer service line when ready to freeze the card, which stops you from being liable for charges made after that call.
- You are not responsible for unauthorized charges made after you report the card lost, and your liability for charges before the call is capped at $50 under federal law.
- Request a replacement card during the same call — most issuers can mail a new card within 5 to 10 business days, or offer a rush option for a fee.
- Check your account online or by phone for any fraudulent charges in the days after you report it lost, and dispute any charges you did not make.
- If you find the card later, do not use it — the replacement card will arrive and the old one will remain inactive.
Request a replacement card and ask about rush delivery
During the same call, ask the issuer to send you a replacement card. Standard delivery usually takes 5 to 10 business days. If you need the card sooner — for example, if you have a trip coming up — ask whether they offer rush or expedited shipping. Some issuers provide this at no cost, while others charge a flat fee, typically $15 to $35.
The issuer will assign a new card number to your replacement. Any recurring charges tied to your old card number — subscriptions, automatic bill payments, gym memberships — will fail when the new card arrives. You will need to update those merchants with your new number. The issuer can tell you which recurring charges they have on file, though not all merchants report this information.
Ask the issuer whether they can provide a temporary card number you can use online while you wait for the physical card to arrive. Some banks offer this; others do not. If they do, write down the expiration date and CVV, because these are temporary and will change when your new card arrives.
Monitor your account for fraudulent charges
Log into your online account or call the issuer every few days for the next two weeks. Look for any charges you do not recognize. Fraudsters sometimes test a stolen card with a small charge first — $1 or $2 — to see if it will go through before making larger purchases.
If you see a charge you did not make, call the issuer when ready and tell them it is fraudulent. They will open a dispute and investigate. While the dispute is pending, the charge will usually be removed from your balance so you do not have to pay it. The investigation typically takes 30 to 60 days, and the issuer will contact you with the outcome.
Keep records of any fraudulent charges: screenshots of the charge in your account, the date you reported it, and the name of the representative you spoke with. If the issuer denies your dispute, you will have this documentation to support an appeal.
Check your credit reports for signs of identity theft
A lost card is not the same as identity theft, but it is worth checking. Request your free credit reports from AnnualCreditReport.com, the official site run by the three major credit bureaus (Equifax, Experian, and TransUnion). You get one free report per bureau per year.
Look for accounts you did not open — credit cards, loans, or lines of credit in your name. If you find any, contact the issuer when ready and report them as fraudulent. You can also file a report with the Federal Trade Commission at IdentityTheft.gov, which creates an official record and gives you a recovery plan.
If your lost card was the only card in your wallet, the risk of identity theft is lower than if you also lost your driver's license or Social Security card. But checking your reports costs nothing and takes about 15 minutes, so it is worth doing.
Update recurring charges and automatic payments
Once your new card arrives, you will need to update any merchants who charge your card automatically. This includes subscription services (streaming, software, cloud storage), utility companies, insurance providers, and any other business that bills you monthly or yearly.
Log into each account and update the payment method with your new card number, expiration date, and CVV. If you do not update them, the charges will fail and you may face late fees or service interruptions. Some merchants will send you an email notification when a charge fails; others will not.
If you are not sure which merchants have your card on file, check your recent statements for recurring charges. The issuer can also provide a list of recurring transactions, though this list may not be complete because not all merchants report this data to the bank.
Decide what to do if you find the card later
If your card turns up after you have reported it lost and received a replacement, do not use the old card. It is permanently frozen and will not work. You can destroy it by cutting it in half and throwing it away, or you can return it to the issuer by mail if they provide a prepaid envelope.
The replacement card is now your active card. Any charges made on the old card after you reported it lost are not your responsibility, even if someone finds it and tries to use it. The card straightforward will not process the transaction.
Understand your rights and protections
Federal law protects you from liability for unauthorized charges on a lost credit card. If you report the card lost before any fraudulent charges are made, you owe $0. If fraudulent charges post before you report it lost, your liability is capped at $50 per card.
This protection applies to credit cards issued by banks and credit unions. Debit cards have different protections — your liability depends on how quickly you report the loss, and can be as high as $500 if you wait more than 60 days. If your lost card was a debit card, call your bank when ready.
The issuer must investigate any dispute you file and respond within 30 days. During the investigation, the disputed amount is typically removed from your balance. If the issuer rules against you, you have the right to request a written explanation and to submit a statement of your own for your file.
Frequently Asked Questions
Will losing my card hurt my credit score?
No. Losing a card and reporting it lost does not affect your credit score. Your score is based on your payment history, credit utilization, and the age of your accounts — not on whether you lose a physical card. As long as you do not miss payments on the account, your score will not change.
What if I see charges from before I reported the card lost?
Dispute them. Call the issuer and report each charge as fraudulent. Your liability is capped at $50 total for all unauthorized charges made before you reported the card lost, so even if there are multiple charges, you owe no more than $50. The issuer will investigate and remove the charges from your balance while they do.
How long does it take to get a replacement card?
Standard delivery is usually 5 to 10 business days. Some issuers offer rush delivery for a fee, which can arrive in 2 to 3 business days. A few issuers offer when ready card numbers you can use online while you wait for the physical card. Ask about all three options when you call to report the card lost.
Do I need to do anything with my old card number after I get the replacement?
Yes — update any merchants who charge your card automatically. Subscriptions, utilities, insurance, and other recurring charges will fail if you do not provide your new card number. Check your recent statements to find all the merchants you need to update.
What if the issuer says I am responsible for fraudulent charges?
You have the right to dispute their decision. Request a written explanation of why they denied your claim, and submit a written statement of your own explaining why you believe the charges are fraudulent. Send both to the issuer and keep copies. If you still disagree, you can file a complaint with the Consumer Financial Protection Bureau.
