Indodax would like to inform all members that you can use the emergency contact on your account as the main number, provided that you must first change the emergency number. To make this change, if you can still access your account please select profile settings. There, you will find the option to update the emergency phone number. Once you have replaced the emergency number with the new number you want, you can set the old emergency number as your account's main number. However, if you can no longer access your account, the emergency contact cannot be used as the main phone number for your account. Please use another new phone number that has not previously been registered with our system.
