Can someone commit fraud with the bank details printed on your cheque?

USPublished 6 October 2026 · Written by BuyMeWhiskey Editorial Team · How we check facts

Yes. The account and routing details printed on a US check can be useful to a fraudster, but they do not by themselves give someone unlimited access to your bank balance. The real risk is unauthorised checks, account misuse, identity theft or altered payment instructions.

If you see an unauthorised check or suspicious withdrawal, contact your bank promptly and use the fraud channel on your statement or card; CFPB guidance explains common check-fraud patterns.

What the information on a check can reveal

A paper check can display the bank routing number, account number, account-holder name and other identifying details. Those details are part of the payment process, so exposing them is not the same as exposing a password. Still, the information can help someone attempt unauthorised debits, counterfeit checks or identity theft.

CFPB describes check fraud as access to checks or check images being used for unauthorised purchases or withdrawals. That makes the physical cheque, a scanned image and an emailed copy sensitive financial material even when the account itself remains protected by other controls.

Why a check image is more useful to a fraudster

A blank cheque contains payment identifiers, while a completed cheque can add the payee, amount, signature and date. A fraudster who obtains several examples may learn enough to imitate the account holder's normal payment pattern or target a specific account.

Check washing is another risk. CFPB explains that criminals can alter the payee or amount on genuine checks. The problem is therefore not simply someone learning your routing number; it is someone obtaining enough payment information to create or manipulate a transaction.

Can someone drain the account with only a routing and account number?

Not necessarily. A routing number and account number are designed to identify the payment account, and many legitimate transactions use them. A bank will normally apply additional controls to payment activity. But those details can be used in fraudulent ACH or check schemes, so they should not be treated as harmless public information.

The safer mindset is risk reduction. You do not need to destroy every cheque because the numbers are printed on it, but you should avoid sending cheque images casually and monitor the account for transactions you did not authorise.

Safer handling of paper checks

The CFPB recommends practical steps for check safety, including using black permanent marker or black gel ink where appropriate, sending checks directly to a post office rather than leaving outgoing mail in a mailbox, and retrieving incoming mail promptly.

For old or unused checks, destroy them so that the account identifiers are no longer readily readable. Shredding across several pieces is preferable to dropping intact checks into household recycling. The aim is to make reconstruction materially harder for someone searching your rubbish.

What to do if a counterfeit check appears

If a bank statement shows a check you did not write, contact the bank immediately. The objective is to stop further unauthorised payments, understand whether the bank can place account controls, and establish a record of the disputed transaction.

If your checkbook, check images or personal information have also been exposed, ask what additional monitoring or account changes the bank recommends. A fraud incident can spread beyond the single item you noticed, so checking neighbouring transactions matters.

Cashier checks are not automatically safe

Cashier's checks are bank-issued instruments, but the existence of a bank name or official-looking document does not prove that money is good. Fake-check scams commonly rely on the victim depositing a check, seeing provisional funds and then sending real money elsewhere before the counterfeit is discovered.

The safest response to an unexpected check is not to treat the apparent balance as spendable cash merely because a deposit has appeared. Verify the transaction independently with the bank using contact details you obtain yourself.

The balance-sheet view matters

Check fraud is a payments-control problem rather than simply a privacy problem. Your bank account can remain open and funded while a criminal attempts to create a payment using copied credentials. Good monitoring, prompt reporting and careful document handling reduce the period in which an unknown transaction can go unnoticed.

If the account is used for payroll, bill payments or a high volume of transfers, consider whether another account can be kept separate for routine spending. Segmentation can reduce the amount exposed to a compromised payment instrument, although it does not replace bank fraud controls.

Worked example

Illustrative example: Elena mails a legitimate cheque and later discovers that a second cheque appears on her statement for an amount she never authorised. The fraudulent cheque uses details associated with her account.

She records the transaction date and amount.
She contacts her bank through an official number rather than replying to an unexpected message.
She asks the bank to investigate the unauthorised item and whether other checks or payment methods need review.
She checks surrounding account activity for additional unfamiliar transactions.

The example does not assume a particular reimbursement amount or bank policy. The point is the sequence: recognise the item, report it quickly, preserve the evidence and review the rest of the account.

The bank may also advise whether other payment instruments or credentials need attention after the report.

Is it dangerous to write a check because it shows my account number?#

There is a fraud risk, but checks remain a legitimate payment method. The account and routing numbers help a payment system identify your account; they are not a universal password. The greater concern is what a fraudster can do with a complete check or image, especially counterfeit checks or altered genuine checks.

Can a scammer use my routing and account number to take money?#

Those details can be used as part of fraudulent payment activity, but they do not mean a criminal automatically gains unrestricted online access to your bank. The bank's controls and the payment channel matter. Monitor the account and report unauthorised transactions quickly if you see one.

How does check washing work?#

Check washing is a form of check fraud in which criminals remove or alter information written on a genuine check, often changing the payee or amount. CFPB warns that this remains a problem. Limiting access to outgoing mail and avoiding easily altered ink can reduce exposure.

Should I shred old checks?#

Yes, unused checks that you no longer need should be destroyed rather than thrown away intact. A shredder or similarly effective destruction method reduces the chance that someone can reconstruct the cheque number and bank details from discarded paperwork Do not leave intact cheque leaves in household waste.

Are cashier's checks safe from scams?#

A genuine cashier's check is a bank-issued payment instrument, but a fake cashier's check can be used in scams. A deposit appearing in your account is not the same thing as proof that an unknown sender has provided final, irrevocable funds. Verify unexpected checks independently before sending money elsewhere.

What should I do about an unauthorised check?#

Tell the bank promptly, provide the transaction details and ask what fraud controls or account changes are appropriate. CFPB recommends contacting your bank when you encounter check fraud. Keep the original statement, check image and any communications relating to the disputed item.

Should I stop using checks completely?#

Not necessarily. Checks can still be useful, but they need sensible handling because the document exposes payment information. People who rarely write checks can reduce risk by limiting unused check stock, securing completed checks and reviewing bank activity regularly A controlled payment method can still be perfectly reasonable.
