Yes, you can change your phone number online with most banks

Most banks let you update your phone number through their website or mobile app without calling or visiting a branch. Log into your account, find the settings or profile section (often labeled "Account Settings," "Personal Information," or "Contact Details"), and look for a phone number field. The exact steps vary by bank, but the process usually takes under five minutes.

Some banks require you to verify your identity before making the change—they may send a code to your current phone number or email, or ask you to answer security questions. A few banks still require a phone call or in-person visit for phone number changes, particularly if you're changing the number linked to two-factor authentication or fraud alerts. Check your bank's website or app first; if you don't see the option online, call the number on the back of your card to ask whether they offer it.

Key Takeaways

  • Most banks allow phone number changes through their website or app in the settings or profile section.
  • Your bank may require identity verification—such as a code sent to your current phone or email—before processing the change.
  • If you're changing the phone number tied to two-factor authentication, your bank may require a phone call or in-person verification.
  • Update your phone number as soon as possible after switching phones or carriers to avoid missing fraud alerts and account notifications.

Where to find the phone number field in your bank's app or website

Start by logging into your account on your bank's website or opening their mobile app. Look for a menu or icon labeled "Settings," "Profile," "Account Settings," or "My Information"—this is usually in the top right corner of the website or at the bottom of the app. Once you're in that section, search for "Contact Information," "Phone Number," or "Personal Details."

If you cannot find it after checking the main settings area, try searching within the app or website using keywords like "phone" or "contact." Some banks bury this option under "Notifications" or "Security Settings" instead of the main profile area. If the option truly is not available online, your bank's website should say so, or you can call the customer service number on your card to confirm whether they support online changes.

What happens when you submit the change

After you enter your new phone number and click "Save" or "Confirm," your bank will usually send a verification code to either your current phone number or your email address on file. You'll need to enter that code into the app or website to confirm the change is real and that you authorized it. This step protects your account from someone else changing your phone number without permission.

Once you verify the code, the change takes effect immediately in most cases. Your bank will then use the new number for text alerts about large transactions, fraud warnings, and account notifications. If you do not receive the verification code, check your spam folder or wait a few minutes—codes can take time to arrive. If nothing shows up after 10 minutes, go back and try submitting the change again, or contact your bank's customer service line.

Why your bank might require a phone call instead

If your phone number is linked to two-factor authentication (2FA)—the security feature that requires a code sent to your phone to log in—your bank may not let you change it online. The reason is simple: if someone had already compromised your account, they could change the phone number to lock you out. To prevent that, some banks require you to call a customer service representative who can verify your identity through other means, such as your Social Security number or answers to security questions.

Similarly, if you're changing the phone number that receives fraud alerts or overdraft warnings, some banks treat this as a security-sensitive change and require a call. A few banks also require in-person verification at a branch if you're changing the primary contact number on the account. Before you call, have your account number, Social Security number, and a form of ID ready. The call usually takes 5 to 10 minutes.

Timing matters: update your number before you lose access to your old phone

Change your phone number in your bank's system as soon as you switch to a new phone or change carriers, ideally before you cancel or disconnect your old number. If you wait until after your old number is deactivated and your bank tries to send a verification code to that number, the code will not reach you, and you may not be able to complete the change online. You'll then have to call customer service to update it manually.

If you've already lost access to your old number and cannot receive the verification code, call your bank's customer service line right away. Explain that you've switched phones or carriers and cannot access the old number. The representative can verify your identity through other methods and update your phone number directly in the system. This process takes longer than an online change, so it's worth doing the update before you lose access.

What to do if the change does not go through

If you submit your new phone number and the verification code never arrives, first check that you entered the number correctly—a single digit wrong will cause the code to go to the wrong phone. Check your spam and promotions folders in email if your bank sent the code there instead of by text. Wait at least 10 minutes before trying again, as codes can be slow to arrive.

If you've waited and checked everywhere and still have not received a code, try a different verification method if your bank offers one—for example, some banks can send the code to your email instead of your phone. If that does not work either, or if your bank does not offer an alternative, contact customer service by phone or through your bank's secure message system. Have your account number and the new phone number you want to add ready. The representative can verify your identity and make the change for you.

Frequently Asked Questions

Do I need to change my phone number if I get a new phone but keep the same number?

No. If you keep the same phone number when you switch phones, your bank's records do not need to change. Your bank has your phone number on file, not the phone itself. You only need to update it if the actual phone number changes.

Will changing my phone number affect my online banking login?

Only if your bank uses your phone number as part of two-factor authentication. If 2FA is turned on and your bank sends a code to your phone to log in, you'll need to update that number or you won't be able to log in after the old number is deactivated. If your bank uses an authenticator app or email for 2FA instead, changing your phone number won't affect login.

Can I change my phone number if I'm not the primary account holder?

It depends on your bank and your role on the account. If you're an authorized user or joint account holder, you may be able to change only your own contact number, not the primary account holder's. Call your bank to ask what phone numbers you can update and what permissions you have.

How long does it take for my bank to stop using my old phone number?

Once you verify the new number online, the change is usually active immediately. Your bank will send future alerts and notifications to the new number. If you changed the number over the phone with a representative, it may take a few hours to process, but usually no more than one business day.

What if I change my phone number but forget to tell my bank?

Your bank will continue sending alerts and notifications to your old number, which you no longer have access to. You won't receive fraud warnings or overdraft alerts, which could leave your account vulnerable. Update your phone number as soon as you switch carriers or get a new number to stay in the loop.
