What Users Changing Email Should Prepare Before Registering for OKX?
If you plan to change your email soon, the most critical thing to prepare before registering on OKX is not the new email itself, but continued access to your old email. When you later change your email, the system will send a verification code to the old email. If you can't receive it, the change cannot be completed.

1. Confirm the Status of Old and New Emails
Before you start, determine which situation applies to you. This will define the subsequent steps.
Situation A: Old email still accessible
What to do: Confirm that the old email can send and receive mail normally.
How to do: Log in to the old email and check if you can receive a normal test email, or open your OKX account and see if verification emails in "Security Settings" can be received.
Completion standard: You can successfully log in to the old email and view the email content.
If the old email is still in use, the registration process and subsequent email change will be smooth. Just follow the regular steps.
Situation B: Old email is no longer accessible or will soon expire
What to do: Assess the difficulty of changing the email.
How to do: If the old email is a company email about to be reclaimed, or the password is lost and unrecoverable, the email change process will be much more complicated.
Completion standard: Clearly understand the old email's status and be prepared that you may need to contact customer support during the email change process.
2. Which Email to Use for Registration
If you are certain you will change your email soon, we recommend registering directly with the new email.
What to do: Use the new email when registering to avoid the later email change step.
How to do: Enter the new email address on the registration page and complete the verification code.
Completion standard: The account is created successfully, and the login name is the new email.
When registering for OKX, both phone number and email need to be bound. If the phone number is already linked to another account, the new email must be unbound from that account before registering. This rule also applies during email change — the new email must not have been registered on the platform before.
3. Steps to Change Email
If you registered with an old email and need to change it later, follow these steps.
Step 1: Go to Security Settings
Log in to the OKX App and go to "Security Settings" or "Security Center".
Step 2: Initiate the Email Change Request
Click the "Modify" button next to "Email Verification".
The system will require you to complete identity verification (face recognition).
Step 3: Enter the New Email
After passing verification, enter the new email address.
Click to get a verification code; the new email will receive a verification email.
After entering that code, the system will send another confirmation code to the old email. Enter that code to complete the change.
Step 4: Confirm the Binding
The new email appears in Security Settings with status "Bound", and the old email record disappears.
Under the standard process (able to log in, able to receive verification codes), changing the email does not require contacting customer support. Only if you cannot receive verification codes midway will you need to go through additional procedures.
Prerequisites
The old email can normally receive OKX verification emails.
Identity verification (KYC) has been completed.
The new email is not bound to any other OKX account.
The OKX App is installed, as some verification steps (such as face recognition) need to be done on the App.
Common Reasons for Failure
Old email cannot receive verification code: Unsubscribed company email, deactivated email, or spam filtering can all prevent receiving the code. This will cause the email change process to stall.
New email already in use: One email can only be bound to one OKX account. If the new email was previously registered, it needs to be unbound first.
Face recognition failure: Changing email is a sensitive operation that requires face recognition verification. Multiple failures will require contacting customer support.
Risk Reminder
24-hour withdrawal restriction: After changing the email, account withdrawal and C2C selling functions will be suspended for 24 hours.
The old email may still receive notifications: After successful email change, the system will still send a notification email to the old email to confirm that this change was made by you.

FAQ
Q: What content will OKX send to the old email after I change the email?
A: After the change is completed, the system usually sends a notification email to the old email, including the modification time, IP address, and device information, helping you confirm that the operation was authorized by you.
Q: If I want to revert to the old email after changing it, can I do it within 24 hours?
A: You can try, but multiple sensitive operations may trigger risk control. If the old email is still accessible, you can submit another email change request, but you will need to verify your identity again, and the withdrawal restriction timer will reset.
Final confirmation step:
Go to the OKX Security Settings page and check whether the email address displayed under "Email Verification" has been updated to the new email. Then log out and try logging in using the new email as the login name — if you can receive the login verification email and successfully log in, the email change is complete. If you have any withdrawal needs later, please note the 24-hour risk control lock time.
