Instructions on using an email address already linked to a Xiaomi Account to register a new Xiaomi Account

To use an email address that is already associated with an existing Xiaomi Account for registering a new account, you should delete your account permanently. Xiaomi will require you to confirm the deletion request via a verification code sent to your email. Follow the steps to verify and finalize the deletion.
Once the old account has been completely deleted, you can go to the Xiaomi Account registration page and use the same email address to create a new account.
Note:
Deleting a Xiaomi Account is a permanent action. It will erase all associated data, including Xiaomi Cloud files, purchase history, device sync data, and any connected services. Please ensure you have backed up any important data before proceeding.
