A voided check is a blank check from your checkbook with the word “VOID” written in large letters across the front, which makes it impossible to cash or deposit while leaving the routing and account numbers along the bottom edge readable. Employers, landlords, insurers, and lenders ask for one when they need to set up direct deposit or automatic payments, because the numbers printed on the check confirm exactly where to send money or pull it from.
How to Void a Check
Take any unused check from your checkbook and a blue or black ink pen. Write “VOID” in large capital letters across the front, big enough to cover the payee line and the amount box so nobody can fill either one in later. Don’t sign it. A signature muddies whether you meant to authorize a payment.
Keep the lettering clear of the line of numbers along the bottom edge. Those digits are the whole point of the exercise, and the recipient needs to read them.
If your printed address or phone number appears on the check and you’d rather not share it, black it out. The recipient only needs your name, routing number, and account number, so redacting personal contact information doesn’t invalidate the check for its purpose.
One easy habit: jot the check number down in your register or a notes app, along with the date and who received it. When you reconcile the account later, you won’t puzzle over a missing number in the sequence.
Which Numbers on the Check Matter
The bottom of every check carries three groups of digits printed in a magnetic ink font called MICR. Reading left to right:
- The routing number is a nine-digit code identifying your bank. The ACH network uses it to send money to the correct financial institution.1American Bankers Association. ABA Routing Number
- The account number is your individual account inside that bank. It tells the bank which account to credit or debit.
- The check number matches the number printed in the upper corner. It doesn’t matter for electronic transfers.
Some banks reverse the order of the account and check numbers on the MICR line. If one sequence is noticeably longer than the other, the longer one is almost certainly the account number. When in doubt, log into your bank’s app or online portal, where routing and account numbers are usually shown under account details.
When Someone Will Ask for One
Payroll direct deposit is the most common trigger. Your employer’s payroll system needs the routing and account numbers to send wages electronically, and a voided check is a widely accepted way to confirm those details are right. No federal law makes a voided check the required format; it’s just the standard.
Utility companies, landlords, and insurance carriers ask for one when setting up recurring autopay. Lenders may request one to disburse loan proceeds or to run automatic loan payments. Companies that pay independent contractors electronically often ask too. In every case, the job of the voided check is the same: confirm that a real account exists at a specific bank and hand over the numbers needed to reach it.
How to Submit a Voided Check Safely
In an office, handing the physical check to a payroll or HR representative is the simplest route. Remotely, many employers and billers offer a secure online portal where you can upload a scan or a clear photo.2Nacha. Direct Deposit Without a Voided Check? Absolutely!
Don’t send a voided check as an attachment in ordinary unencrypted email. Email can be intercepted, forwarded, or sit indefinitely on servers you don’t control. If the recipient has no secure portal and needs a physical copy, mail it in a sealed envelope rather than sending it by email.
When You Don’t Have Paper Checks
Plenty of accounts, especially online-only and basic checking accounts, no longer come with a checkbook. Three substitutes work in almost every situation a voided check would.
Pre-Filled Direct Deposit Forms
Most banks and credit unions let you generate a direct deposit form through the mobile app or online banking site. The form carries your name, routing number, account number, and account type, which is the same information a voided check would provide. Most employers and billers accept these as a direct substitute.
Account Verification Letter
You can visit a branch and ask for a letter confirming your account details on the bank’s letterhead or with an official stamp. Some banks charge a small fee, so ask before ordering one. A letter on bank stationery tends to carry more weight than a photocopy of a check when the recipient is cautious about fraud.
Micro-Deposit Verification
Some companies skip the voided check entirely and send one or two tiny deposits, each under a dollar, to the account you gave them. You log in, confirm the exact amounts, and the company knows you have access to the account. The deposits typically arrive within one to two business days. Nacha rules require these micro-entries to include “ACCTVERIFY” in the transaction description and to use a recognizable company name, and any offsetting debits can’t exceed the credits, so the process won’t leave your account short.3Nacha.

Protecting Your Banking Information
A voided check can’t be cashed, but it displays the two numbers someone would need to attempt a fraudulent ACH withdrawal. That’s worth taking seriously even when the recipient is a legitimate employer or biller.
Handling and Disposal
Only hand a voided check to a party you trust, and only through a channel you trust. Once the recipient confirms the setup is complete, destroy any spare copies. Shredding is best. Tearing into small pieces works if you don’t have a shredder. Don’t drop a voided check into a public trash can with the numbers still legible.
Federal Liability Limits if Something Goes Wrong
If someone misuses your banking information to run an unauthorized electronic transfer, the Electronic Fund Transfer Act caps your exposure based on how quickly you report it:
- Report within two business days of learning about the unauthorized transfer, and your liability is capped at $50 or the amount transferred before you notified the bank, whichever is less.4Office of the Law Revision Counsel. 15 USC 1693g – Consumer Liability
- Report after two business days but within 60 days of receiving the statement showing the transfer, and your liability can rise to a maximum of $500.5eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
- Wait longer than 60 days and you could be on the hook for the full amount of any unauthorized transfers that happened after that window closed, if the bank can show it could have stopped them had you reported sooner.
These deadlines have exceptions for extenuating circumstances like hospitalization or extended travel, in which case the bank must grant a reasonable extension.4Office of the Law Revision Counsel. 15 USC 1693g – Consumer Liability Check your statements regularly, and turn on your bank’s real-time transaction alerts if they’re available. Catching an unauthorized debit fast is the single biggest factor in how much money you might lose.
