If a new employer or a billing department has just asked you for a "voided check," the request can sound stranger than it is. You are not giving anyone money and you are not signing anything away. You are simply handing over a check that has been deliberately spoiled — marked VOID so it cannot be cashed — for one reason: it carries your bank's routing number and your account number in a format they can trust. Those two numbers are all that is needed to point a deposit or a recurring payment at your account.
This guide explains exactly what a voided check is, why you keep getting asked for one, how to void a check correctly in under a minute, and what your options are if you do not have a paper checkbook at all. When you simply need the document itself, you can also create a voided check online and skip the checkbook entirely — but read on first, because in many cases you may not need a voided check at all.
What is a voided check, exactly?
A voided check is an ordinary personal or business check that has been cancelled by writing the word VOID across the front in large letters. The mark makes the check worthless as a payment instrument — a bank or teller will not honor it — but it leaves the pre-printed numbers along the bottom edge fully readable.
That bottom row is the entire point. It is printed in a machine-readable font (the MICR line) and contains three things: your bank's nine-digit routing number, which identifies the financial institution; your account number, which identifies your specific account; and the check number. A voided check is, in effect, a piece of paper your bank has already validated that says "this routing and account number belong to a real account here." That is why a payroll or billing system trusts it more than a number you type into a form, where a single transposed digit can misroute the money.
- It cannot be cashed or deposited — the VOID mark cancels it.
- It does still display your routing number, account number, name, and usually your address.
- It authorizes nothing on its own; it only supplies verified account details.
Why do employers and companies ask for a voided check?
Almost every request comes down to one of two things: someone wants to send money into your account, or someone wants to pull money out of it on a schedule. In both cases they need your verified routing and account numbers, and historically a voided check was the easiest way to prove them.
The most common reason by far is direct deposit. When you start a new job, payroll uses your routing and account numbers to deposit your wages through the ACH network instead of cutting a paper check. If this is your situation, the step-by-step guide on setting up direct deposit at a new job walks through exactly what payroll needs. The U.S. Consumer Financial Protection Bureau notes that to set up a direct deposit you simply "need to know your… account number and… routing number" — a voided check is one convenient way to hand both over accurately.
The second big reason is automatic payments. To set up autopay for rent, a mortgage, utilities, insurance, a gym membership, or retirement contributions, the company needs your account details so it can debit you on a recurring basis. As the CFPB explains, automatic payments work because "you give a company your checking account or debit card information and authorize them to electronically withdraw money from that account on a recurring basis." A voided check supplies that information cleanly.
- Direct deposit of wages, a pension, government benefits, or a tax refund.
- Recurring autopay for rent, mortgage, utilities, insurance, or subscriptions.
- Linking your bank account to a payroll, benefits, brokerage, or loan provider.
- Verifying account ownership when opening an investment account or applying for a loan.
How do you void a check?
Voiding a check takes about thirty seconds and a pen. The goal is to make the check impossible to use for payment while keeping the account information at the bottom perfectly legible. Take any blank check from your checkbook — you do not need to fill in a payee, date, or amount — and do the following:
- Use a medium or fine blue or black pen. Avoid a thick marker that could bleed through onto the numbers.
- Write VOID in large capital letters across the front of the check, big enough to span the middle of it.
- Keep the routing and account numbers along the bottom edge clear — do not write over the MICR line.
- Do NOT sign the check. A voided check needs no signature, and leaving it unsigned removes any risk if it goes astray.
- Make a record. Note the check number in your register or snap a photo, so you can track that this check was spoiled rather than lost.
Some people prefer to write VOID in smaller letters in each separate field — the date line, the payee line, the amount box, the amount line, and the signature line — instead of one large mark. Either approach is fine; the only firm rules are that the cancellation is unmistakable and the bottom numbers stay readable. Once voided, you can hand the check to whoever requested it or scan and send a copy.
What if you don't have a checkbook?
Plenty of people bank entirely online and have never ordered paper checks. The good news is that a voided check is just a delivery method for two numbers, so there is almost always another way to provide them. In fact, Nacha — the organization that governs the ACH network behind direct deposit — has pointed out that the voided check is increasingly optional, because financial institutions "typically make account and routing numbers readily available to customers that sign in to online and mobile banking," and many now offer pre-filled direct deposit forms.
If the company will accept it, the simplest fix is often just to give them your routing and account numbers directly, or a bank-generated direct deposit form. If they specifically insist on a voided check, you still have several options:
- Ask your bank for a counter check or a pre-printed voided check. A teller or your branch can usually print one on the spot.
- Request a bank verification letter on official letterhead stating your name, account number, and routing number — this is often accepted in place of a check.
- Use a deposit slip from the back of your checkbook, which carries the same routing and account numbers (confirm the recipient accepts one — see the comparison below).
- Generate a voided check online by entering your details into a tool that produces a printable, correctly formatted document.
- Find the numbers yourself in your bank's app or website, then type them into the company's enrollment form.
Whichever route you take, confirm with the requester which documents they accept before you submit anything, so you are not chasing paperwork twice.
What information does a voided check reveal, and is it safe to give one?
A voided check is reasonably safe to hand to a legitimate recipient, but it is not nothing. It exposes your bank's routing number, your account number, your name, and frequently your home address. Those details cannot be used to log into your bank or to drain your account by themselves, but in the wrong hands they could be used to set up an unauthorized ACH debit or attempt fraud, so a voided check deserves the same care as the checkbook it came from.
Treat it sensibly: give a voided check only to a party you trust and have a real reason to deal with — your actual employer's payroll department, a known lender, an established biller. Hand it over through a secure channel rather than plain email when you can, and never leave voided checks lying around. The reassuring part is your right to undo recurring withdrawals: if a company you authorized for autopay starts taking payments you did not intend, the CFPB says you can revoke permission by telling the company and then your bank, ideally in writing, and that after you do so "any additional payments initiated by that company would be errors, and you can contact your bank for a refund."
Common voided-check mistakes to avoid
Most problems with voided checks come from one of a handful of avoidable slips. Watch for these:
- Covering the numbers. Writing VOID over the routing or account number at the bottom makes the check useless to the recipient. Keep that row clear.
- Signing it. There is never a reason to sign a voided check, and an unsigned spoiled check is far safer.
- Using a deposit slip when a check is required. A deposit slip's printed routing number is sometimes a different internal number than the one on a check — verify the recipient will accept one.
- Sending it insecurely. Emailing a photo to the wrong address or posting it anywhere exposes your account details. Use a trusted channel.
- Assuming it authorizes the deposit. A voided check only supplies your numbers; you still complete and sign the employer's or biller's enrollment form to actually authorize the transfer.
- Closing the old account too soon. If you provided the check to switch where money lands, keep the previous account open until you confirm the first deposit or payment runs on the new one.
The bottom line
A voided check is a small, low-risk document that does one job: it proves your routing and account numbers to someone who needs to send money to, or collect money from, your account. You rarely truly need a paper one anymore — your account number and routing number, a bank letter, or a pre-filled form will often do — but when a request specifically calls for a voided check and you do not have a checkbook handy, you can create a voided check online in a couple of minutes. Either way, keep the bottom numbers legible, never sign it, and share it only with people you trust.
