Please note that the phone number is pulled from the number that the doctor has on file. If you do not have access to that phone number and want to change it indefinitely, you will have to contact your doctor and have them update your phone number. Once they have changed the phone number on file, your doctor will then need to reset your account, which will send you a new registration email with a link to Access your records. You can follow the registration instructions here.
If you need immediate access to your records, you can ask that your doctor provide you the PIN number associated with your invitation, as you can set up your account with your Date of Birth and PIN number OR your Date of Birth and Security Code that is sent to your phone. If the doctor's office did not provide you with your PIN initially, you will need to contact them to obtain your PIN.
