Call your bank right now, before you do anything else
The moment you realize your card is gone, call the phone number on the back of another card, your bank statement, or your online banking app. Do not use a number you find by searching — scammers create fake bank websites. Your bank can freeze the card in seconds, which stops anyone from using it even if they find it.
When you call, have your account number ready. The bank will ask you to verify your identity — usually your Social Security number, date of birth, and answers to security questions you set up. They will deactivate the card when ready. This takes less than five minutes.
If it is after hours, call anyway. Most banks have 24-hour fraud lines. The call will route to a live person or an automated system that can freeze your card without waiting for morning.
Key Takeaways
- Call your bank's fraud line when ready — the number is on your statement or app, not from a web search — to freeze the card before anyone can use it.
- Your bank will send a replacement card to your address on file, usually arriving within 5 to 10 business days, though some banks offer expedited delivery for a fee.
- You are not responsible for fraudulent charges made after you report the card lost, but you may be liable for charges made before you called if you were negligent.
- While you wait for the replacement, you can still access your money through your bank's app, ATM, or by visiting a branch in person.
- If your card was used fraudulently before you reported it, file a dispute with your bank within 60 days of seeing the charge on your statement.
What happens to charges made before you called
Federal law limits your liability for unauthorized charges, but the limit depends on when you report the loss. If you report the card lost before anyone uses it, you owe nothing. If someone uses the card before you call, your liability caps at $50 — but only if the card itself was used in person or online. If the thief used your card number without the physical card, you typically owe nothing.
Most banks waive the $50 entirely as a matter of policy, even though the law allows them to charge it. Call and ask. If your bank refuses, you can dispute the charge, and the bank must investigate.
The clock starts when you report the loss to your bank, not when you discover the fraudulent charge. This is why calling when ready matters — every hour you wait extends the window in which someone can charge to your account.
How to get a replacement card
When you freeze your card, the bank will offer to send a replacement. Standard delivery takes 5 to 10 business days to your address on file. Some banks offer expedited delivery — overnight or two-day — for a fee of $10 to $25, or sometimes free if you have a premium account.
Ask the bank which option they offer and what it costs. If you need cash before the card arrives, you can withdraw from an ATM using your PIN, visit a branch and show your ID, or use your bank's app to send money to another account or to a person via their service.
The replacement card will have a new number. Any subscriptions or automatic payments tied to your old card number will fail when the new card arrives. You will need to update those accounts — streaming services, insurance, utilities — with the new number. Your bank can tell you which charges were set to your old card.
Checking for fraudulent charges while you wait
Log into your online banking or app daily while you wait for the replacement. Look at your recent transactions and flag anything you do not recognize. Fraudsters often test a stolen card with small charges first — $1 or $2 — before attempting larger purchases.
If you see a charge you did not make, contact your bank when ready. Do not wait for your statement. The bank will open a dispute, freeze the charge, and credit your account while they investigate. The investigation usually takes 10 business days, though the bank must return your money within two days if the charge is clearly unauthorized.
Keep records of when you reported the loss and the name of the person you spoke to. Write down the time and date. If a dispute arises later, this documentation proves you reported the loss promptly.
What to do if your card was used fraudulently
If you see charges on your statement that you did not make, file a dispute with your bank within 60 days of the charge appearing. This is a legal important date — after 60 days, the bank can refuse to investigate.
Call the fraud line or use your online banking to report the charge. The bank will ask you to describe what happened and confirm you did not authorize it. They will place a temporary credit in your account while they investigate, usually within two business days. The investigation takes up to 10 business days.
If the bank determines the charge was unauthorized, the credit becomes permanent and the charge is removed. If they determine you authorized it or cannot prove otherwise, they will reverse the credit. This is rare when you report the loss promptly.
Protecting yourself while using your account without a card
Until your replacement arrives, you can still pay bills and move money. Use your bank's app to transfer funds, pay bills online, or send money to another person. You can also visit a branch in person with your ID and ask a teller to withdraw cash or process a payment.
ATMs work with your PIN, not your card number, so you can withdraw cash at any ATM that accepts your bank. If you do not know your PIN, call the bank and ask them to reset it or send it to you.
Avoid giving your account number to anyone over the phone unless you initiated the call to your bank's official number. Scammers sometimes call people who have reported lost cards, pretending to be the bank, and ask for account details to "verify" the loss.
If your card turns up later
If you find your card after you have reported it lost and received a replacement, do not use the old card. Destroy it by cutting it in half or shredding it. The old card number is deactivated and will not work, but physically destroying it prevents confusion.
If someone else finds your card and tries to use it after you reported it lost, the transaction will be declined. The card is useless to them. There is no risk in keeping the old card around, but destroying it removes any chance of accidental use.
Frequently Asked Questions
Can I use my debit card number online if the card is lost?
No. Once you report the card lost, the number is deactivated and will not work for online purchases. Use your bank's app to pay bills or transfer money instead. If you need to make an online purchase, wait for the replacement card or use a different payment method.
What if I lost my card while traveling?
Call your bank's international fraud line when ready — the number is usually on your statement or in your app. Tell them where you are. Many banks can overnight a replacement card to a hotel or local branch. If that is not possible, ask about a temporary card number they can issue over the phone, or use your app to access cash through a partner bank or ATM network.
Do I have to pay for the replacement card?
Most banks send the first replacement free. If you lose multiple cards in a short period, some banks charge $5 to $15 for additional replacements. Expedited delivery — overnight or two-day — usually costs $10 to $25, though premium account holders may get it free. Ask your bank what they charge.
How long does it take to dispute a fraudulent charge?
Your bank must credit your account within two business days if the charge is clearly unauthorized. The full investigation takes up to 10 business days. You must report the charge within 60 days of it appearing on your statement, or the bank can refuse to investigate.
What if my bank says I am responsible for the fraudulent charges?
Ask the bank to explain in writing why they believe you authorized the charges. If you reported the loss promptly and did not act negligently, federal law limits your liability to $50. If the bank refuses to budge, you can file a complaint with your state's banking regulator or the Consumer Financial Protection Bureau. Document everything — the date you reported the loss, the person's name, and the charges in question.
