Call your bank right now, before you do anything else

The moment you realize your card is gone, call the phone number on your bank statement or the back of another card you have. Do not use a number from a Google search — scammers create fake bank websites and phone lines. Your bank can freeze the card in seconds, which stops anyone from using it even if they find it.

Have your account number ready when you call. 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 when you opened the account. This takes about five minutes. Once the card is frozen, it will not work at ATMs, stores, or online, even if someone else has it.

If your bank has a mobile app, you can often freeze the card yourself without calling. Open the app, find the card settings, and look for a "freeze" or "lock" option. This is faster than calling during business hours, though calling is still the safest route if you are not sure whether the app will actually block the card immediately.

Key Takeaways

  • Call your bank immediately using the number on your statement or another card, not a number from an online search, to freeze the card within minutes.
  • Fraudulent charges made before you report the card lost are your bank's responsibility under federal law, but only if you report it promptly.
  • A replacement card typically arrives in five to ten business days, though some banks offer expedited shipping for a fee or next-day delivery.
  • While you wait for the replacement, you can use your mobile wallet, online banking transfers, or a temporary digital card if your bank offers one.
  • Check your account for unauthorized charges for at least 60 days after reporting the card lost, and report any fraudulent transactions to your bank in writing.

Your liability for charges made before you reported it

Federal law (the Electronic Funds Transfer Act) protects you from most fraudulent charges, but only if you report the card lost within a specific window. If you report it lost before any fraudulent charges appear, you owe nothing. If charges show up before you notice and report the card, your liability depends on how quickly you act.

If you report the card lost within two business days of discovering the fraud, you are liable for no more than $50 of unauthorized charges. If you wait longer than two business days but report it within 60 calendar days of your statement showing the fraudulent charge, you could be liable for up to $500. If you do not report it within 60 days of your statement, you could lose the entire amount that was fraudulently charged.

This is why calling immediately matters — the clock starts the moment you discover the card is missing, not the moment the fraud happens. Write down the date and time you called your bank. If you later dispute a charge, you will need to prove when you reported the card lost.

How long a replacement card takes and what to do while you wait

Most banks mail a replacement card within five to ten business days. Some banks offer rush delivery for $15 to $25, which can get the card to you in one to three business days. A few banks offer a temporary digital card that you can add to your phone's mobile wallet (Apple Pay, Google Pay, Samsung Pay) the same day you report the card lost — this works at most stores and online, even though the physical card has not arrived yet.

While you wait, you have several ways to access your money. You can withdraw cash at an ATM using your PIN if you remember it, transfer money to another account through your bank's website or app, pay bills online through your bank's bill pay feature, or use a debit card from a different bank if you have one. If your bank offers a temporary digital card, that is usually the fastest way to make purchases.

If you need cash urgently and cannot wait for a replacement card, call your bank and ask whether they can issue a temporary card at a branch location. Some banks will print one on the spot if you show up in person with ID. Others will not. It is worth asking.

Checking your account for fraud over the next two months

After you report the card lost, log into your online banking or mobile app at least once a week for the next 60 days. Look at every transaction — even small charges like $1 or $2 that might seem like test charges. Fraudsters sometimes make tiny charges first to see if the card works, then make larger ones later.

If you see a charge you did not make, contact your bank immediately. Do this by phone first, then follow up in writing (email or letter) within 10 days. Include the date you called, the name of the person you spoke to, the fraudulent transaction amount, the date it posted, and the merchant name. Keep a copy for your records. Your bank has 10 business days to investigate and either remove the charge or explain why it was legitimate.

Some banks will remove the charge temporarily while they investigate, crediting your account within a few days. Others will leave it there until the investigation is complete. Either way, you should not have to pay it if you reported it on time.

What happens if someone used your card before you reported it lost

If fraudulent charges already appear on your account when you call to report the card lost, tell the bank representative about them during that call. The bank will note this in your account. Do not assume the charges will be removed automatically — you will likely need to dispute each one separately, even though you reported the card lost at the same time.

The bank will send you a dispute form (often called a "claim form" or "fraud report form") by mail or email. Fill it out for each fraudulent charge, sign it, and return it within the deadline they give you — usually 10 to 30 days. Include copies of any evidence you have: receipts from the actual merchant showing you were somewhere else, screenshots of your location data if you have it, or anything else that proves you did not make the charge.

If the charge was made at a physical store and you were not there, that is usually enough. If the charge was online, the bank may ask more questions because online fraud is harder to prove. Either way, keep records of everything you send to the bank.

Protecting yourself after you get the replacement card

When the new card arrives, sign the back of it immediately. Activate it through your bank's website, app, or phone line before you use it — most banks require this step. Update any recurring charges (subscriptions, insurance payments, automatic bill pay) that were linked to the old card, because those will fail once the old card is deactivated.

If you had set up automatic payments for loans, credit cards, or utilities using the old card, contact each company and provide the new card number. Some will update automatically when you activate the new card, but others will not. Check your account with each company to be sure.

Consider whether you want to change your PIN or set up additional security features. Some banks offer card alerts that text or email you every time the card is used, which can help you spot fraud faster next time. Others let you set spending limits or turn the card off and on through the app. These features do not prevent fraud, but they make it easier to catch.

If your card was stolen and used for large amounts

If someone used your card to make purchases of several hundred dollars or more before you reported it lost, the bank's fraud investigation may take longer than 10 business days. Federal law gives banks up to 45 days to complete the investigation in some cases. During this time, the fraudulent amount may stay on your account, even though you are not responsible for paying it.

Ask your bank whether they will issue a provisional credit while they investigate. This is not the same as removing the charge — it is a temporary credit to your account so you can access the money while the bank looks into it. Not all banks do this automatically, so you may need to request it. If they refuse, ask to speak to a supervisor.

If the investigation takes more than 10 business days and the bank has not given you a provisional credit, follow up in writing. Send a letter to the bank's dispute department (the address should be on your statement or the bank's website) restating the fraudulent charges, the date you reported the card lost, and the date you first contacted them. Keep a copy and send it certified mail so you have proof of delivery.

Frequently Asked Questions

Can I use my old card number online after I report it lost?

No. Once you report the card lost and the bank freezes it, the card number will not work anywhere — not at stores, not at ATMs, and not online. This is why updating recurring charges is important. If you have subscriptions or automatic payments linked to that card, they will fail and you may get late fees if you do not update them quickly.

What if I find my card after I already reported it lost?

Call your bank and tell them you found it. They can unfreeze it if you want, though many people choose to keep it frozen and just use the replacement. Do not use the old card at an ATM or store if there is any chance someone else had access to it, because they may have written down the number or the PIN.

Do I have to pay for the replacement card?

Most banks issue the first replacement for free. If you lose a second card or request expedited shipping, some banks charge $15 to $25. Check your bank's fee schedule or ask when you call to report the card lost. A few banks charge for all replacements, so it is worth knowing your bank's policy.

What if my bank says the fraudulent charges were legitimate?

If the bank completes their investigation and concludes the charges were authorized, you can dispute their decision. Send a written response to the dispute department within 30 days, explaining why you believe the charges were fraudulent. Include any new evidence you have found. The bank must respond to your second dispute, though they are not required to reverse the charges if they still believe they were legitimate.

Should I report the lost card to the police?

You do not have to, and most police departments will not investigate a lost card unless it was stolen as part of a larger crime (like a robbery or burglary). If your wallet was stolen, you may want to file a police report for insurance purposes or to have a record in case the thief uses other documents from your wallet. But for the card itself, reporting it to your bank is what matters.
