You can request a new account number from your bank, but the reason matters and the process varies by bank

Most banks will issue you a new account number if you ask, but they treat the request differently depending on why you want one. If you've had fraud or unauthorized activity on your account, the bank may issue a new number as part of their fraud resolution process — sometimes without you asking. If you simply want a fresh number for privacy or organizational reasons, you'll need to call or visit your branch and make the request directly. The bank will close your old account and open a new one with a different number, though the account itself stays in your name and at the same branch.

The catch is that changing your account number creates work on your end. Any automatic payments, direct deposits, or standing orders tied to your old number will stop working unless you update them. Your employer's payroll system, your utility companies, your subscription services — all of these need the new number. The bank won't do this for you. You have to contact each one separately and provide the new details.

Key Takeaways

  • You can request a new account number by calling your bank's customer service line or visiting your branch in person, and most banks will process the request within one to three business days.
  • If your account has been compromised by fraud or unauthorized activity, the bank may issue a new number automatically as part of their fraud investigation, sometimes without waiting for you to ask.
  • After you receive a new account number, you must update it with your employer's payroll department, all billers who pull money from your account, and any services that deposit money to you.
  • Your old account will be closed once the new one is active, so verify that all recurring transactions have been switched over before the closure date to avoid missed payments or bounced deposits.
  • Some banks charge a small fee for issuing a new account number if the request is not related to fraud, though many waive the fee if you explain the reason.

When the bank issues a new number without you asking

If your account has been compromised — someone used your account number to make unauthorized charges, or you reported fraud — your bank's fraud department may close the account and open a new one with a different number as part of the resolution. This is standard practice and protects you by cutting off access to the old account. The bank will typically do this within a few days of confirming the fraud claim.

You'll receive notice of the closure and the new account number by mail or email, depending on your bank's communication preferences. The bank will also usually offer to reissue your debit card if the old one was compromised. However, the bank will not automatically notify your employer, your landlord, or anyone else who deposits money to you. That notification is your responsibility, and delays in updating those parties can mean missed paychecks or late deposits.

How to request a new account number for non-fraud reasons

Call your bank's main customer service number or visit your branch and ask to speak with an account representative. Tell them you want to close your current account and open a new one with a different account number. You don't need to provide a detailed reason — banks process these requests routinely — but if you mention a specific concern (such as privacy or a data breach at a third party), the representative may note it in your file.

The bank will walk you through the process, which usually involves signing a form to authorize the closure and opening of the new account. They'll give you the new account number on the spot or within one business day. Some banks charge a small fee for this service if it's not fraud-related, typically $10 to $25, though many waive it if you ask or if you've been a customer for a long time. Ask before you agree to proceed.

Updating automatic payments and direct deposits

This is the most time-consuming part of changing your account number. You need to contact every organization that either pulls money from your account or deposits money to it. Start with your employer's payroll or HR department — they need the new number so your paychecks go to the right place. Then contact your utility companies, insurance providers, loan servicers, and any subscription services that charge your account monthly.

For each one, you'll need to provide your new account number and routing number (which usually stays the same). Some organizations let you update this information online through their website or app. Others require a phone call or a written request. Keep a list as you go so you don't miss anyone. A common mistake is forgetting about a service you don't use often — a gym membership you've paused, an old insurance policy, or a charity donation you set up years ago. These will try to charge the old account and fail, which can trigger overdraft fees or late-payment notices.

Timing: when the old account closes and what happens to pending transactions

Your bank will usually keep the old account open for 30 to 60 days after opening the new one, giving you time to update your recurring payments. However, don't wait until the last day. Start updating as soon as you have the new number, because some organizations take several business days to process the change. If a payment tries to go through to the old account after it's closed, it will bounce, and you may face overdraft fees or late charges.

Ask your bank specifically when the old account will close and whether they'll accept deposits to it after that date. Some banks will still accept incoming deposits to a closed account and hold them temporarily, then contact you to redirect them. Others reject deposits outright. Knowing this helps you time your updates correctly — you want all direct deposits moved over before the closure date, but you have a small window to catch any stragglers.

What to do if you've already given out your old account number widely

If you've shared your account number with many people or organizations and you're worried about updating them all, consider whether a new number is actually necessary. If the concern is privacy rather than fraud, you might manage the risk by monitoring your account closely instead. If the concern is fraud or unauthorized activity, the bank should issue a new number as part of their fraud response, so the work is necessary.

If you do proceed, prioritize the updates: employer payroll first, then regular billers (utilities, insurance, loans), then optional services. For any organization you can't reach or that won't accept the new number, contact your bank and ask whether they can help you redirect the payment or flag the old account to forward deposits. Some banks offer this service, though it's not may provide.

Fees and what to expect from different banks

Most large national banks (Chase, Bank of America, Wells Fargo, Citibank) do not charge a fee for a new account number if the request is fraud-related. If it's not fraud-related, fees range from $0 to $25, and many banks waive the fee if you ask or if you maintain a minimum balance. Credit unions typically charge less or nothing. Online banks vary — some charge nothing, others charge $10 to $15. Call your bank and ask before you commit.

The time to receive the new number is usually one to three business days. If you need it urgently, visit your branch in person — they can often issue a temporary number the same day and mail the official documentation later. Ask whether the bank can expedite the process if you explain that you need the number for an upcoming direct deposit or payment.

Frequently Asked Questions

Will my routing number change if I get a new account number?

No. Your routing number identifies your bank and branch, not your individual account. It stays the same. You only need to update the account number portion when you contact employers, billers, and other organizations. Some people mistakenly think they need a new routing number too, which can cause confusion when updating payments.

What happens to checks I've already written with my old account number?

Checks will bounce if they're deposited after your old account closes. Contact anyone you've written checks to and ask them to wait for a new check with the updated account number, or provide them with the new number directly if they're willing to update their records. For checks you've already mailed, call the recipient as soon as possible.

Can I keep my old account open while using the new one?

Some banks will keep both accounts open if you ask, though this is not standard. Most banks close the old account automatically after 30 to 60 days. If you want to keep both open — for example, to receive final deposits to the old account while using the new one — ask your bank whether they allow this and whether there are any fees for maintaining two accounts.

If my bank issued a new number because of fraud, will the fraudster be able to use the old number?

No. Once your bank closes the old account, it cannot be used for deposits or withdrawals, even if someone has the number. The old account is dead. However, the fraudster may still have your other information (name, address, Social Security number), so monitor your credit report and watch for new fraud attempts on other accounts or in your name.

How long does it take for direct deposits to start going to the new account?

This depends on when your employer processes the change. If you update your employer's payroll system immediately, the change usually takes effect on the next pay cycle. If your next paycheck is in two weeks, the new account number should be active by then. For other organizations, allow one to two pay cycles for the change to go through. Always verify that the first deposit went to the new account before assuming the update worked.
