If you are no longer able to access your account and your account is locked or requires login confirmation but the registered phone number is inactive:

In the event that your account is locked and you no longer have access to the registered primary mobile phone number, you will not be able to receive the SMS PIN necessary to unlock your account. Please be aware that the SMS PIN will only be sent to the registered primary mobile phone number on your account. Therefore, you need to update your primary mobile phone number first. Here are the instructions to change your primary mobile phone number if your account is locked:

If you are accessing your account via Indodax website:

• Proceed to the 'Unlock Account' page or 'Login Confirmation' page and select the 'Lost Your Phone Number?'
  
• Subsequently, you will encounter a data submission page. Provide your new mobile phone number and choose an active registered phone number (such as a relative's mobile phone) to receive the verification PIN via SMS. Upon receiving the SMS PIN, enter it in the 'PIN' box, and then click the 'Submit' button to successfully complete the process of changing your primary phone number
  
• Once the primary mobile phone number has been successfully changed, you can proceed to unlock your account by sending the account unlock PIN to the new primary mobile phone number.

Note: In case your account has not been verified, please note that on the data entry page, you will be unable to choose a relative's phone number as the recipient of the SMS PIN.

Therefore, in the 'Active Registered Number' section, you need to select 'Not Available' (this option can also be chosen if the registered primary/relative's mobile phone number associated with your account is no longer active). You can then provide the reason for the phone number change and attach a photo of your identification card. Finally, click 'Submit'. Your data change request will be entered into our system and processed with a maximum estimated duration of 7 working days.

If you are accessing your account via Indodax Application:

• In the Unlock Account/Locked Account menu, if your registered number is still active, you can choose 'Send OTP' to receive the OTP code, which will be sent to the registered mobile phone number that is still active. However, if your registered mobile phone number is no longer active, you can select the option 'Lost phone number?' to submit a data change request for the registered mobile phone number.
• In the Change Mobile Phone Number menu, please input your new mobile phone number, provide the reason for the data change, and upload your identification. Once completed, click on 'Submit Data'. Your data change request will be recorded in our system and processed within a maximum estimated time of 7 working days.
