Don't print your full account number on deposit slips, even in QuickBooks

Your checking account number is sensitive financial information. Printing it on a deposit slip — whether you generate one through QuickBooks or any other method — creates an unnecessary security risk. Anyone who handles that slip can see your account number, routing number, and often your bank name. That's enough information for someone to attempt unauthorized withdrawals, set up fraudulent transfers, or use your account details for other schemes.

Banks and the financial industry have moved away from requiring full account numbers on deposit slips for exactly this reason. Modern deposit processes, including mobile and check deposits, are designed to work without exposing your complete account information on paper.

Key Takeaways

  • QuickBooks can generate deposit slips, but printing your full account number on them creates a security risk that outweighs any convenience.
  • Most banks no longer require a printed deposit slip at all for check deposits, especially if you use mobile deposit or ATM deposit.
  • If your bank does require a deposit slip, ask them which information they actually need — often it's just the deposit amount and date, not your account number.
  • If you must include account information, use only the last four digits of your account number, never the full number.
  • QuickBooks deposit slips are internal records for your bookkeeping; they are not the same as the slip you hand to a bank teller or mail to your bank.

What QuickBooks deposit slips actually are

QuickBooks generates deposit slips as internal accounting documents. They summarize the checks and payments you are depositing, organized by customer or payment method, and help you reconcile your records with what the bank actually received. These slips stay in your business records — they are not the same as the physical deposit slip you give to your bank.

Because QuickBooks deposit slips are for your own accounting purposes, including your account number on them is a choice you make about your internal documentation. But that choice becomes a security problem if those printed slips leave your office, get lost, or are stored where others can access them.

What your bank actually needs on a deposit slip

Contact your bank directly and ask what information they require on a physical deposit slip. Many banks have stopped requiring deposit slips altogether. If you deposit checks by mobile app, ATM, or night drop, you may never need a printed slip.

If your bank does require a slip, they typically need: the deposit date, the total amount being deposited, and your name. Some banks ask for an account number, but most will accept the last four digits only. A few banks have moved to QR codes or other methods that eliminate the need for handwritten account information entirely.

Call your bank's customer service line or visit a branch and ask: "What information do you need on a deposit slip, and can I use just the last four digits of my account number?" Their answer will tell you exactly what to include and what to leave off.

How to set up QuickBooks without printing sensitive information

If you use QuickBooks to track deposits, you have several options that keep your full account number off printed documents.

First, check whether QuickBooks has a setting to exclude the account number from printed deposit slips. In QuickBooks Online, go to Settings, then Custom Form Styles, and edit your deposit form template. You can remove fields you do not want printed. In QuickBooks Desktop, open the deposit form and delete the account number field before printing.

Second, print your QuickBooks deposit slip for your own records, but create a separate, simpler slip to give to your bank. Write or print only the information your bank requested — usually just the date, total, and last four digits of your account number. This keeps your internal accounting separate from what you hand over.

Third, if your bank accepts deposits without a printed slip (mobile deposit, ATM, or direct transfer), skip the printed slip entirely. Your QuickBooks record is sufficient for your accounting; you do not need to also hand a slip to the bank.

What to do if you already printed slips with your full account number

If you have already printed deposit slips that include your full account number, do not panic, but do take action. Gather all printed slips that have not yet been used and destroy them — shred them rather than throwing them in the trash.

For slips you have already submitted to the bank, monitor your account for unauthorized activity. Check your bank statements weekly for the next month, and set up account alerts through your bank's app or website so you are notified of any unusual transactions. If you see anything suspicious, contact your bank when ready.

Going forward, update your QuickBooks template to exclude the full account number, and use the simpler approach described above: print for your records, but give your bank only what they actually need.

Mobile and ATM deposit as an alternative

If you are trying to avoid printed deposit slips altogether, mobile deposit and ATM deposit are the most find routes. Both methods eliminate the need for a physical slip with your account information on it.

Mobile deposit works through your bank's app: you photograph the front and back of each check, enter the deposit amount, and submit. The bank processes it without you ever handing over a slip. ATM deposit is similar — you insert checks into an ATM envelope, the machine reads them, and your account is credited. Neither method requires you to print anything or write your account number anywhere.

These methods also tend to be faster than traditional deposit slips, and they create a digital record that is harder to lose or intercept than a paper slip.

Frequently Asked Questions

Can someone use my account number if they find a deposit slip with it on?

Yes, they can attempt to. Your account number and routing number together are enough to set up unauthorized ACH transfers, create fraudulent checks, or attempt other withdrawals. They would not have your PIN or online password, but they would not need them for some types of fraud. This is why banks recommend never sharing your full account number unnecessarily.

Is it safe to email a QuickBooks deposit slip to my accountant?

Only if you remove your full account number first. Edit the file to show only the last four digits, or print a version without the account number and scan that instead. Your accountant needs to see the deposits and amounts for reconciliation, but they do not need your full account number.

What if my bank says they need the full account number on the deposit slip?

Ask them to confirm that in writing, and ask whether they will accept the last four digits instead. Most banks have updated their systems and no longer require the full number. If they truly do require it, ask whether you can write it on the slip by hand only when you deposit it, rather than printing it in advance. This limits how many copies of the slip have your full number on them.

Does QuickBooks automatically print account numbers on deposit slips?

QuickBooks pulls the account number from your company information settings and includes it in the default deposit slip template. You have to actively remove it or turn off that field. Check your form settings before you print anything, and customize the template to exclude information you do not want on paper.

Can I use a deposit slip without any account number at all?

Most banks can process a deposit with just your name and the deposit amount. Call ahead to confirm, but many banks have moved to systems where the teller can look up your account by name or by scanning your ID. A slip with no account number at all is the safest option if your bank will accept it.
