Voided Check vs Deposit Slip for Direct Deposit

If you're setting up direct deposit, use a voided check. It shows your bank's real routing number and your account number in the exact format payroll systems expect. A deposit slip can carry a different internal number that direct deposit will reject, which is why many employers ask for the check specifically.

Why the two documents aren't the same

A voided check is a blank check with the word VOID written across it. Writing VOID means no one can cash or deposit it, but the printed numbers stay readable. That's the whole point. You're sharing your account details, not paying anyone.

A deposit slip is the small form you fill out to put money into your account at a branch or an ATM. It records a deposit. It was never built to hand your account details to an outside company.

Both connect to the same account, so they look interchangeable. They aren't, and the difference comes down to one number.

The routing number is where deposit slips fall short

Your routing number is the nine-digit code that tells the banking network which bank to send money to. Direct deposit runs on it. (The system behind it is called ACH, short for Automated Clearing House, the network banks use to move money electronically between accounts.)

A voided check prints your routing number and account number along the bottom in a special magnetic-ink font called the MICR line (Magnetic Ink Character Recognition). That bottom row is the number your bank actually uses for electronic transfers, and it's the one payroll needs.

Here's the catch with deposit slips. Some banks print a different routing number on them, an internal one used only for processing deposits inside the bank. It is not the same as the electronic-transfer routing number, and if payroll enters it, your direct deposit fails. Not every bank does this, but enough do that most payroll departments won't take the chance. That's the real reason a voided check became the standard.

When each one is accepted

Reach for a voided check when you're:

• Setting up direct deposit for a paycheck
• Authorizing automatic payments on a loan, mortgage, or utility bill
• Linking your checking account to a brokerage, a savings app, or another bank

A deposit slip is really only useful for:

• Making a deposit in person or at an ATM, which is its actual job
• Casually showing that an account exists, when no money is moving

If a form or an employer asks for "a voided check or deposit slip," read it as: the check is the safe option, and the slip might work. When in doubt, send the check. Requirements vary, so it's worth confirming with whoever is asking.

What to do if you only have one

If you only have a checkbook: pull a check and void it. Write VOID in large letters across the front, covering the payee line, the amount box, and the signature line, but leave the numbers at the bottom clear. That's your document. There's a fuller walkthrough in how to void a check.

If you have deposit slips but no checks: don't send the slip on its own for direct deposit. Do one of these instead:

• Log into your bank's website or app and look under Account Services or Documents for a direct deposit form. It's a PDF with your real routing and account numbers already filled in, made for exactly this.
• Ask your bank for a voided-check image or a short account verification letter on its letterhead. Both are widely accepted.
• If you need something in the next minute, you can create a voided check with your details in the correct format.

If you bank online-only: those banks rarely mail checkbooks, so use the direct deposit form or verification letter in the app. A quick message to their support usually gets it emailed to you the same day.

Sending it safely

Whichever document you use, it carries your name, account number, and routing number, so treat it like cash. Upload it through an employer's secure portal when they offer one. Regular email isn't encrypted, so if you have to email it, password-protect the PDF and share the password by text or a quick call. And never post a photo of it publicly.
