To void a check, take a blank check from your checking account, grab a pen with blue or black ink, and write the word VOID in large capital letters across the front. Make the letters big enough to cover the payee line, the amount box, the date, and the signature line, but keep them clear of the row of numbers printed along the bottom edge. That’s the whole task. The check can no longer be cashed or deposited, but the routing and account numbers along the bottom stay readable, which is the reason anyone asked you for a voided check in the first place.
The Steps in Order
Use a pen, never a pencil. Pencil erases; ink doesn’t.
Write VOID once, large, across the middle of the check. A single word covering most of the face is enough. Some people prefer to write it a second time across the signature line, or across the amount box, and that’s fine, but one clear VOID across the front is all that’s needed to make the check unusable.
Keep your marks off the bottom edge. That strip is called the MICR line, and reading from left to right it contains three groups of numbers: your bank’s nine-digit routing number, your account number, and the check number.1Cornell Law School. 12 CFR Appendix A to Part 229 – Routing Number Guide Those are the numbers your employer or biller needs to pull off the check, so they have to stay legible.
Write down what you did. In your check register, or wherever you track your account, note the check number and mark it voided. If that check number ever shows up as a posted transaction on your statement, you’ll know something is wrong.
If You Already Filled the Check Out
A check you wrote but haven’t handed to anyone can still be voided the same way. Write VOID across the front in large letters, keep the MICR line clear, and log it in your register. The signature doesn’t matter once the word VOID is on the face of it.
Once the check is in the payee’s hands, writing VOID on your carbon copy or stub does nothing. Your only move at that point is to call your bank and request a stop payment. Stop payments usually cost somewhere between about $15 and $35 depending on the bank and how you place the order, and the order may expire after six months unless you renew it.
Why Someone Asked for One
The usual reasons are direct deposit of a paycheck and automatic payment of a recurring bill. Payroll departments use the routing and account numbers on the voided check to set up an electronic link through the ACH network, which is what actually moves money on payday. The same setup applies to autopay on a mortgage, rent, insurance premium, utility bill, or retirement contribution, and to recurring loan repayments and government benefit deposits like Social Security or a tax refund.
The check is used because it carries your bank details in a printed, machine-readable form. That’s harder to mistype than numbers read off a screen or copied into a form.
How to Send It Without Exposing Your Account
You’ll usually be asked to upload the voided check to a secure portal, send it as a scanned PDF, or hand over a physical copy. If you photograph or scan it, check that the MICR line is sharp and every digit is readable in the image.
Email is the risky channel. If you have to email a voided check, password-protect the PDF before attaching it, and send the password in a separate message. When your employer’s HR system offers an upload through an encrypted portal, use the portal instead.
After you submit the check, the first real deposit or payment may not happen for a few business days. Payroll and billing systems often run a small non-monetary test through the ACH network first to confirm the account is valid.2Payments Innovation Alliance. ACH File Overview
What to Do if You Don’t Have a Checkbook
Plenty of people don’t keep paper checks anymore. You can still set up direct deposit or autopay. Nacha, which governs the ACH network, lists several substitutes that employers and billers commonly accept.3Nacha. Direct Deposit Without a Voided Check? Absolutely!
- Log in to your online or mobile banking. Most banks show your routing and account numbers there, and some will generate a prefilled direct deposit form or a printable digital voided check.
- Call your bank. A representative can read the numbers to you after verifying your identity.
- Ask for a bank verification letter on the bank’s letterhead confirming your name, account number, and routing number. Branches can usually print one on the spot, sometimes for a small fee.
- Use the employer’s own direct deposit authorization form, which typically just asks for routing number, account number, and account type.
- Hand over an unused deposit slip from your checkbook, which carries the same numbers, though not every employer accepts one.
Keep the Account Safe Afterward
A voided check can’t be cashed, but it still shows your full name, routing number, and account number. Anyone who gets hold of that combination could try to set up an unauthorized ACH withdrawal, print a counterfeit check, or use the numbers for online payments. A few habits reduce the exposure:
- Don’t text a photo of a voided check or send it as an unprotected email attachment.
- Void one check per request. Extras don’t help anyone and can get lost.
- Shred any voided check the recipient didn’t end up needing.
- Watch your statements for unfamiliar activity in the weeks after you shared the check.
If you spot a transaction you didn’t authorize, call your bank right away to freeze or close the account. You can also file a report at IdentityTheft.gov, which walks you through a recovery plan.
