Any verified user can make updates to their Doximity profile. Simply log on to the website, Click "Edit Profile" to get into Edit Mode. From there, navigate to the contact information section and click "Edit".
Please note: If your cell or personal phone number is listed on your profile, it is because you or your representative entered that as part of your government-maintained NPI record. Doximity is not able to change the information listed in the NPI directory—you will need to contact the NPI directly to change your information there.
