You can change your phone number in Fidelity through your account settings online, 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 when ready. If you prefer to do it by phone, call the number on the back of your Fidelity card or statement and speak to a representative, who will verify your identity before making the change. You can also visit a local Fidelity branch in person with a photo ID.

Fidelity uses your phone number to contact you about account activity, send two-factor authentication codes when you log in, and reach you if there are issues with your investments or transfers. Keeping it current matters because an outdated number can lock you out of your account or delay important notifications.

Key Takeaways

  • The online method through your account profile is the quickest — you can change your number in minutes without calling or visiting a branch.
  • Fidelity will ask you to verify your identity before updating your phone number, whether you do it online, by phone, or in person.
  • Your phone number is used for account alerts, two-factor authentication, and contact during emergencies, so updating it promptly prevents access problems.
  • Changes made online or by phone take effect within minutes, but allow a few hours for the update to sync across all Fidelity systems.

Changing your number online through your Fidelity account

Log into your Fidelity account at fidelity.com using your username and password. Once you are in your account dashboard, look for a settings or profile menu — this is usually in the top right corner or under an account menu. Click on "Profile" or "Account Settings" (the exact label depends on which Fidelity product you use, but the location is consistent).

Find the section labeled "Contact Information" or "Personal Information." Your current phone number will be listed there. Click the edit or pencil icon next to the phone number field. Enter your new number in the format Fidelity requests (usually with area code), then click save or confirm. Fidelity may send a verification code to your new number or ask you to confirm the change through an email sent to your registered email address.

Once you confirm, the change is live in your online account when ready. However, it can take a few hours for the update to reach Fidelity's phone systems and other connected services, so if you call Fidelity within the next few hours, a representative might still see your old number in their system.

Changing your number by phone with a Fidelity representative

Call the customer service number on the back of your Fidelity card, statement, or the Fidelity website. Have your account number and a form of photo ID ready — the representative will ask you to verify your identity before making any changes to your account.

Tell the representative you want to update your phone number. They will ask for your new number and may ask you to confirm it by repeating it back. Some representatives will also ask security questions (such as your mother's maiden name or the last four digits of your Social Security number) to verify you are the account holder. Once verified, the representative will update your number in the system and confirm the change with you before ending the call.

Changes made by phone take effect within minutes. If you are calling from the old phone number, the representative may offer to send a confirmation text or email to your new number so you know the change went through.

Changing your number in person at a Fidelity branch

Visit a Fidelity branch location near you with a photo ID (driver's license, passport, or state ID). You can find branch locations and hours on the Fidelity website by entering your zip code. Tell a representative you want to update your phone number on your account.

The representative will ask to see your ID and may ask security questions to confirm you are the account holder. Once verified, they will update your number in the system and provide you with a receipt or confirmation. This method is useful if you prefer face-to-face interaction or if you have other account questions to address at the same time.

What happens if you forget to update your number

If your phone number changes and you do not update it in your Fidelity account, you may miss important alerts about your account. Fidelity sends notifications about large transfers, unusual activity, and password reset requests to the phone number on file. If that number is no longer yours, someone else might receive those messages, or you might not get alerts you need.

More importantly, if you set up two-factor authentication (which Fidelity recommends for security), you will not be able to log into your account if you cannot receive the verification code on your registered phone number. This can lock you out until you contact Fidelity to verify your identity and update the number.

If you have already lost access to your account because your phone number changed, call Fidelity's customer service line and explain the situation. They can verify your identity through other means (such as your Social Security number, account number, and answers to security questions) and update your phone number so you can regain access.

Updating phone numbers for joint accounts or authorized users

If you have a joint account or have authorized another person to manage your account, each person's phone number is stored separately. The primary account holder can update their own number through the methods above. If an authorized user wants to update their phone number on file, they can do so by logging into their own profile or by calling Fidelity and verifying their identity.

Changes to one person's phone number do not affect the other person's contact information. If you are the primary account holder and want to update the phone number for an authorized user, you may need to contact Fidelity directly — some account types do not allow this through the online portal.

Frequently Asked Questions

Will changing my phone number affect my account access or investments?

No. Changing your phone number does not affect your account balance, investments, or any holdings. It only updates how Fidelity contacts you and how you receive two-factor authentication codes when logging in. Your account itself remains unchanged.

How long does it take for my new phone number to work everywhere in Fidelity?

Changes take effect when ready in your online account and within minutes for phone and in-person updates. However, it can take a few hours for the new number to sync across all Fidelity systems, including their phone lines and mobile app. If you call Fidelity within a few hours of updating, a representative might still see your old number.

Can I update my phone number if I do not have access to my current phone?

Yes. Call Fidelity's customer service line and explain that you no longer have access to your old phone number. They will verify your identity through security questions and other information, then update your number without needing a code sent to your old phone. Have your account number and photo ID information ready.

What if I want to remove my phone number entirely instead of changing it?

You cannot remove your phone number from your Fidelity account — Fidelity requires at least one contact method on file. However, you can update it to a different number, such as a work phone, a family member's number, or a new personal number. If you want to use a different type of contact method, contact Fidelity to discuss your options.
