You can change your phone number in Fidelity through your online account, by phone, or in person at a branch

The fastest way is to log into your Fidelity account online, go to your profile settings, and update the number yourself — this takes about two minutes and takes effect immediately. If you prefer not to use the website, you can call Fidelity's main customer service line and a representative will change it for you over the phone. If you have a local Fidelity branch, you can also walk in with a photo ID and update it there.

Fidelity uses your phone number to contact you about account activity, send two-factor authentication codes, and reach you if there are issues with your trades or transfers. Keeping it current matters because an outdated number can lock you out of your account if you need to verify your identity, and you may miss important alerts about your investments.

Key Takeaways

  • You can update your phone number online through your account settings, by calling Fidelity customer service, or by visiting a branch in person with photo ID.
  • Online changes take effect immediately, while phone and in-person updates may take a few minutes to process.
  • Fidelity uses your phone number for security codes, account alerts, and contact about transactions, so updating it promptly prevents lockouts.
  • If you change your number before updating Fidelity, you may not receive the text code needed to log in — contact customer service to verify your identity another way.

Changing your number online through your account

Log into your Fidelity account at fidelity.com using your username and password. Once you are on the dashboard, look for your name or profile icon in the top right corner and click it to open the menu. Select "Profile" or "Account Settings" — the exact wording depends on which Fidelity platform you use, but it is always in that menu.

Find the section labeled "Contact Information" or "Phone Number." Click "Edit" next to your current number, enter your new phone number, and save the change. Fidelity may ask you to confirm the new number by sending a code to your email or existing phone number — follow the prompts to complete verification. Once confirmed, the change is live.

Changing your number by phone

Call Fidelity's main customer service line at 1-800-343-3548. A representative will ask you to verify your identity by providing your account number, Social Security number, or answers to security questions you set up when you opened the account. This verification step protects your account from unauthorized changes.

Once verified, tell the representative your new phone number and they will update it in the system. Ask them to confirm the number back to you before you hang up to make sure it was entered correctly. The change usually takes effect within a few minutes, though it may take up to an hour to appear across all Fidelity systems.

Changing your number at a Fidelity branch

If you have a Fidelity branch near you, you can visit in person and update your number at the desk. Bring a photo ID — a driver's license, passport, or state ID card. A branch representative will verify your identity, confirm your account, and update your phone number on the spot.

Branch hours vary by location, so check the Fidelity website or call ahead to confirm when your nearest branch is open. This method is useful if you prefer face-to-face contact or if you are already in the branch for another reason.

What happens if you change your phone number before updating Fidelity

If you switched to a new phone number and have not yet told Fidelity, you may run into trouble the next time you log in. Fidelity uses two-factor authentication, which means it sends a security code to your old phone number to confirm your identity. If you no longer have access to that number, you cannot receive the code and cannot log in.

If this happens, call Fidelity customer service at 1-800-343-3548 and explain that you changed your phone number. A representative can verify your identity using other methods — your account number, Social Security number, or answers to security questions — and then update your number without requiring the text code. This process usually takes 10 to 15 minutes.

Updating phone numbers linked to specific accounts or services

If you use Fidelity for multiple purposes — a brokerage account, a retirement account, and a banking service, for example — the phone number you update in your main profile applies to all of them. You do not need to change it separately for each account.

However, if you have set up alerts for specific accounts or subscribed to text notifications about certain investments, those alerts will now go to your new number automatically. If you want to stop receiving alerts to your new number, you can adjust notification settings in your account preferences.

Frequently Asked Questions

How long does it take for a phone number change to take effect?

Online changes take effect immediately. Changes made by phone or in person usually process within a few minutes to an hour. If you need to log in right after changing your number, wait at least 15 minutes to allow the system to update.

Can I change my phone number if I do not have access to my old number?

Yes. Call Fidelity customer service and explain that you no longer have access to your old phone number. They will verify your identity using your account number, Social Security number, or security questions, then update your number without requiring a text code.

Will changing my phone number affect my account security?

No. Updating your phone number actually improves security because Fidelity will send future security codes and alerts to the correct number. Make sure the new number is one only you can access.

What if I entered my phone number incorrectly?

If you notice the error right away, log back into your account and correct it immediately. If you realize later that the number is wrong, call Fidelity customer service at 1-800-343-3548 and they will fix it for you.

Do I need to update my phone number if I only use Fidelity on a computer?

Yes. Even if you do not use the Fidelity mobile app, Fidelity uses your phone number to send security codes when you log in from a new device or location, and to contact you about account alerts. Keeping it current protects your account.
