Update your bank account contact information directly through your bank
You can change your phone number, email, or mailing address on your bank account by logging into your online banking portal, calling your bank's customer service line, or visiting a branch in person. Most banks let you make these changes yourself in seconds through their website or app. If you call, have your account number and a form of ID ready—the bank will verify your identity before making any change.
The method you choose depends on how quickly you need the change made and whether you're comfortable doing it online. Online changes usually take effect immediately. Phone and in-person changes typically process within one business day, though some banks apply them right away.
Why this matters: your bank uses your phone number to send fraud alerts, deposit notifications, and password reset codes. Your mailing address is where statements and tax documents go. If either is wrong, you may miss critical security alerts or important mail from your bank.
Key Takeaways
- Log into your online banking portal or mobile app and look for "Account Settings," "Profile," or "Contact Information" to change your phone number or address yourself.
- Call your bank's customer service number on the back of your debit card or on your statement; have your account number and ID ready for verification.
- Visit a branch in person with your ID if you prefer to make the change face-to-face or if you do not have online access.
- Online changes usually take effect immediately, while phone and in-person changes typically process within one business day.
- Update your phone number promptly if you change carriers or get a new phone, because your bank uses it to send fraud alerts and security codes.
Changing your number through online banking
Log into your bank's website or app using your username and password. Look for a menu option labeled "Account Settings," "Profile," "My Information," "Contact Information," or "Preferences"—the exact wording varies by bank. Click into that section and find the field for phone number or email address.
Enter your new phone number in the format your bank requests (usually with area code and no dashes or parentheses). Some banks ask you to verify the new number by sending a code to that phone via text or by calling it. Follow the prompts to confirm. Once confirmed, the change is usually live within seconds.
If you cannot find the contact information section, use your bank's search function or help menu. You can also call customer service and ask them to walk you through the steps for your specific bank's platform.
Changing your number by phone
Call the customer service number on the back of your debit card, on your most recent statement, or on your bank's website. Tell the representative you want to update your phone number or mailing address. They will ask for your account number and will verify your identity by asking for information only you would know—such as your Social Security number, date of birth, or recent transaction amounts.
Once verified, give the representative your new phone number or address. They will read it back to you to confirm accuracy. Ask them when the change will take effect—most banks process phone requests within one business day, though some make the change immediately.
Request confirmation via email or ask for a reference number so you have a record of the request. If the change does not appear in your account within the timeframe given, call back and reference that number.
Changing your information in person at a branch
Bring a valid photo ID (driver's license, passport, or state ID) to any branch of your bank. Tell a teller or banker that you want to update your phone number or mailing address. They will verify your identity using your ID and your account information, then make the change on the spot.
Ask for written confirmation of the change, or take a photo of your receipt showing the update. This gives you proof in case you need to follow up later. In-person changes are usually processed immediately, though it may take a few hours to appear in your online account.
What happens if you do not update your phone number
If you change your phone number but do not tell your bank, you will miss fraud alerts and security notifications sent via text or call. If someone tries to access your account or make a large transfer, your bank may send a code to your old number—which you will not receive. This can delay your ability to confirm legitimate transactions or stop fraudulent ones.
You also will not receive one-time passwords (OTPs) needed to reset your online banking password or approve certain transactions. If you lose access to your account and cannot receive these codes, you may have to visit a branch or call customer service to regain access, which takes longer.
Additionally, if your bank sends statements or tax documents (like 1099 forms) to an outdated mailing address, you may not receive them. This can cause you to miss payment deadlines or miss important account information.
Updating your number after switching phone carriers
When you switch carriers or get a new phone, your phone number usually stays the same—but if it changes, update your bank immediately. Do this before you cancel service with your old carrier, because your bank may send a verification code to your old number during the update process.
If you already cancelled your old service and cannot receive the verification code, call your bank's customer service line instead. Explain that you switched carriers and cannot access your old number. They can verify your identity through other means and update your number without requiring a code.
Changing your address for statements and mail
Your mailing address is separate from your phone number in most bank systems. If you move, update your address through the same method you would use for your phone number: online banking, phone, or in person. Some banks send statements electronically by default, but they still need your mailing address on file for tax documents, legal notices, and physical debit cards.
If you set up paperless statements, your bank may still mail you certain documents that cannot be sent electronically—such as 1099 forms at tax time or notices of account changes. Make sure your mailing address is current even if you do not receive regular statements by mail.

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

No. Banks require identity verification before allowing any change to account contact information. Only you (or someone with power of attorney over your account) can make this change.
