To void a check, take a pen with permanent blue or black ink and write “VOID” in large capital letters across the front of the check, stretching the word from the payee line through the signature line. Leave every other field blank. That’s the whole procedure. Knowing how to void a check matters because the voided slip gives an employer, biller, or agency your bank’s routing number and account number for electronic payments without letting anyone withdraw money from the account.
The Steps
Use a felt-tip marker or ballpoint with permanent ink so no one can erase the word later. Make the letters big enough that nobody could squeeze a dollar amount or payee name around them. Do not scribble so hard that you cover the numbers printed along the bottom edge of the check.
That bottom row is the MICR (Magnetic Ink Character Recognition) line, and it is the whole reason the voided check is useful. It carries the nine-digit routing number that identifies your bank, followed by your account number.1American Bankers Association. ABA Routing Number Payroll processors and billing systems read those digits to set up your electronic payments. Ink over them and the check is useless.
Leave the rest of the check empty. No signature, no date, no payee, no amount. A signature is what turns a piece of paper into a live payment instrument, so adding one to a voided check creates a security risk you do not want.2Legal Information Institute. Uniform Commercial Code 3-401 – Signature Once you’ve written VOID, note the check number in your register so you don’t wonder later where it went.
Why Someone Is Asking for One
The most common request comes from a new employer setting up direct deposit. Payroll or HR uses the routing and account numbers to send your pay electronically, a process governed by the Electronic Fund Transfer Act and its implementing rule, Regulation E.3eCFR. 12 CFR Part 205 – Electronic Fund Transfers (Regulation E)
Landlords, utility companies, insurers, and loan servicers ask for one when you sign up for automatic monthly payments. They use the details to schedule ACH debits from your account, and you’ll usually sign a separate authorization form giving them permission to pull the money.
Federal law requires Social Security and Supplemental Security Income payments to be delivered electronically, so enrollment involves providing your bank details to the Treasury.4Social Security Administration. Direct Deposit The IRS lets you request direct deposit on your tax return. If you want to split a refund across two or three accounts, Form 8888 collects the routing number, account number, and account type for each.5Internal Revenue Service. Form 8888 – Allocation of Refund A voided check isn’t strictly required for these, but having one nearby helps you copy the digits correctly.
Brokerages, robo-advisors, and online savings platforms sometimes ask for a voided check image when you link an external bank account. It works as a backup check on the numbers you typed in.
Handing It Over
For digital submission, take a clear, well-lit photo or scan and upload it through the employer’s payroll portal or the requesting organization’s secure website. Make sure the full MICR line is legible in the image. Don’t send voided check images over unencrypted email. If the organization has no secure upload option, ask whether they’ll take a direct deposit form instead.
For a physical handoff, put the check in a security-tinted envelope and mail it through a tracked service. Don’t paperclip anything over the MICR line.
After receiving your banking details, most companies verify the account before sending real money. Some run a prenote, a zero-dollar test transaction confirming the account exists and accepts electronic transfers. Others send one or two micro-deposits of a few cents and ask you to confirm the exact amounts. Micro-deposits usually show up in your transaction history within two to three business days. Once the account is verified, you’ll get a confirmation and recurring payments will start.
What to Do If You Don’t Have Paper Checks
Plenty of accounts no longer come with checks, and most organizations accept substitutes. Banks generally show your routing and account numbers inside online and mobile banking, and some generate a prefilled direct deposit form you can download and give to your employer.6Nacha. Direct Deposit Without a Voided Check? Absolutely!
If your bank doesn’t offer that form, ask a branch or customer service for a direct deposit verification letter. It confirms your name, routing number, account number, and account type on bank letterhead, and most employers and billers accept it in place of a voided check.
A third option is to fill out your employer’s own enrollment form by hand, copying the routing and account numbers from your bank’s website, app, or a recent statement. Double-check every digit. A transposed number sends your pay to the wrong account, and fixing it can cost a full pay cycle.
Mistakes That Ruin the Check or Expose the Account
- Signing it. A signature turns paper into a potentially negotiable instrument. Leave the signature line blank.
- Writing over the MICR line. If the digits at the bottom are covered or smudged, automated systems can’t read them and the receiving organization will send you back to start over.7Federal Reserve. MICR-Line Issues Associated With the Check 21 Act and the Boards Proposed Rule
- Using pencil or erasable ink. If VOID can be erased, the check can be filled out and presented for payment.
- Filling in a payee or amount. Even with VOID across the face, extra details create unnecessary risk. A blank check with only VOID on it gives a fraudster nothing to work with.
- Emailing the image unencrypted. An email with your full account number bouncing across servers is a data leak waiting to happen. Use the secure portal.
Throwing It Away
Once the organization confirms the account is linked and the first payment has cleared, you don’t need the paper anymore. Don’t drop it in the trash or recycling. A voided check still shows your full account number, routing number, name, and address.
A cross-cut shredder is the simplest fix at home. Cross-cut models slice paper in two directions and produce confetti that is effectively impossible to reassemble. Strip-cut shredders leave long ribbons that someone could piece back together, so they are less secure for financial documents. If you don’t own a shredder, many banks, office supply stores, and community groups host periodic shredding events for free destruction, and some office supply chains offer year-round drop-off shredding for a small fee.
The Risk You’re Taking by Sharing the Numbers
A routing number and account number together are enough for someone to attempt an unauthorized ACH debit. This is the most common form of account-number fraud, and consumer protections exist precisely because it happens.
Federal law caps your liability for unauthorized electronic transfers, but the cap depends on how quickly you report. Notify your bank within two business days of discovering an unauthorized transaction and your maximum loss is $50. Wait longer than two business days but report within 60 days of the statement showing the charge and your exposure rises to $500. Wait beyond 60 days and you can be on the hook for the full amount of any transfers the bank can show it would have stopped had you reported sooner.8Office of the Law Revision Counsel. 15 USC 1693g – Consumer Liability
The practical version: only share a voided check with organizations you trust, submit it through secure channels, and read your bank statements. Catching a fraudulent charge in the first two days keeps your exposure at its lowest.
