You can contact Fidelity Investments by phone at 1-800-343-3548. Fidelity account holders can also get support on Reddit at r/fidelityinvestments or via live chat on Fidelity’s website. Secure email is another support option, but you must be logged in to your account to access this feature. Fidelity customers that live near a Fidelity branch can choose to get help in person, too.
