What is a voided check?

A voided check is a regular check with the word VOID written in big letters across the front. Voiding it means no one can use it to take money out of your account. But every number a company needs to send money into your account stays printed and readable. That is the whole point: it is a safe way to share your bank details.

What a voided check is

Start with a blank check from your own checkbook. Write VOID across the front, big enough to cover the middle of the check. The check is now dead as a payment. Nobody can fill it in and cash it.

What does not change is the printed information. Your name, your bank's name, your routing number, and your account number are all still there and still easy to read. A company uses those printed numbers to connect to your account. So a voided check does two jobs at once: it cannot be spent, and it shows your real account details.

Exactly what information it shares

A voided check is basically a printed record of the account it came from. Here is what someone sees on it:

• Your bank's name, and often its logo, usually near the top.
• Your name and address, printed in the top left corner.
• The routing number. This is a nine-digit code that identifies your bank. Think of it as the bank's address inside the payment system.
• Your account number. This points to your specific account at that bank, so money lands in yours and not someone else's.

The routing and account numbers show up again along the bottom of the check, printed in a blocky font. That row is called the MICR line (short for Magnetic Ink Character Recognition, a special ink that machines can scan). Payroll systems and banks read that line to pull your numbers automatically, which is why they trust a check more than a number you typed by hand.

What a voided check does not show matters too. It does not reveal your balance, your debit card PIN, or your online banking password. Someone holding it could send money to your account or set up a withdrawal, but they cannot log in as you.

How it differs from a normal check

A normal blank check is a payment waiting to happen. Fill in a name and an amount, sign it, and the person you hand it to can cash or deposit it. That is exactly what you do not want when you are only trying to share account details.

Voiding flips that around. The VOID mark cancels the check so it can never be cashed, even though the account numbers stay visible. One rule follows from this: never sign a voided check. Your signature is what makes a check spendable, and a voided check should never be spendable.

Why companies ask for one

Two reasons. It proves the account is really yours, and it gives your exact numbers with no typos. A single wrong digit can send a paycheck to the wrong place or bounce a bill, so many companies would rather read the numbers off a check than trust what you type into a form.

You will usually be asked for one when you set up:

• Direct deposit for a paycheck, so your employer can send pay straight to your bank. For the setup steps, see using one for direct deposit.
• Automatic bill payments through ACH (the Automated Clearing House, the network banks use to move money between accounts electronically), for things like a mortgage, car loan, or utility bill.
• Tax refunds and government benefits, such as an IRS refund or a Social Security payment sent by direct deposit.

Most employers and billers accept a voided check for this, though some will also take a bank letter or their own direct deposit form instead. It is worth confirming what a specific company wants before you send anything.

How to get one

The simplest way is free: pull a check from your checkbook and write VOID across it. If you do not keep paper checks anymore, you still have options. Many banks can print one for you or let you handle it inside online banking, and some employers accept a signed direct deposit form in place of a check. The full list of choices is in our guide on how to get a voided check.

If you need one quickly and have no checkbook, you can also create a voided check online from your bank details. However you get it, confirm the routing and account numbers are correct and clearly readable before you hand it over.

Is a voided check safe to hand over?

For a normal request you expected, it is fine, and it is safer than typing your numbers into an email. The check cannot be cashed, and the details on it are the same ones printed on every check you write. Even so, treat it with care. Only give it to a company you trust and were expecting to ask, and send it through a secure upload or portal rather than plain email when you can.
