What to Do If You Entered the Wrong Phone Number During OKX Registration?
If you filled in an incorrect phone number during registration, the most direct fixes are: modify the number directly in the App if you can still log in to your account; if you cannot even access your account, reset your details via the "Cannot Verify" entry. Below we explain the solutions for different scenarios you may encounter.

1. Prerequisite: Confirm your current status first
Before you take any action, clarify what situation you are facing, which will directly determine which solution you need to follow.
Scenario A: You entered the wrong number but have already logged in successfully
You have used the incorrectly filled number to receive the verification code and completed the full registration process
Your account is currently in a logged-in state
You can follow the "Already Logged In" workflow for this case
Scenario B: You entered the wrong number, cannot receive the verification code, and have not finished registration
You mistyped the number during registration, so the verification code was sent to a stranger's mobile phone
You are stuck in the registration flow and cannot log in to any account
For this case, you can directly re-register: restart the full registration process with a correct, accessible phone number
Scenario C: You completed registration with the wrong number that does not belong to you
You can log in to the account (because you filled in an email or received the verification code at the time), but the bound phone number belongs to another person
For this case, you need to replace the bound phone number of the account
Confirm which scenario matches your situation before proceeding to the next steps.
Common failure note: Many users assume they must contact customer support immediately after entering a wrong phone number, but most cases can be resolved via self-service. Try the DIY solutions first before reaching out to human agents.
2. Modify your phone number when you are already logged in
If you have successfully logged in to your account and only need to replace the currently bound phone number with your correct one, you can finish the operation directly in the OKX App.
Operation Steps:
Open the OKX App, tap the "Profile" or 9-grid menu icon on the top left corner
Go to [Security Settings] → [Phone Number]
Tap [Modify Phone Number]
Complete the required identity verification (you may need to finish face recognition or Google Authenticator verification)
Enter your new correct phone number, get and input the SMS verification code
Tap Confirm to finish the modification

Completion confirmation: After the modification succeeds, your new phone number will be displayed on the Security Settings page, and the system will send you a confirmation email or SMS notification.
Risk Reminder: Within 24 hours after you modify or reset your bound phone number, your account cannot withdraw crypto or conduct C2C sell orders. This is the platform's official security protection mechanism, not a system fault. (Source: OKX Official Help Center, 2026-07-14)
3. Reset your phone number when you cannot log in
If you are locked out of your account and cannot receive verification codes due to the wrong phone number, you can reset your details via the "Cannot Verify" entry.
Operation Steps:
Enter your account ID and password on the login page
After you are redirected to the secondary verification page, tap [I Need Help] or [Cannot Verify]
Select [Reset Phone Number] or [Reset Security Verification Methods]
Complete the required identity verification as prompted on the page (you may need to finish face recognition, email verification, etc.)
Set your new correct phone number

If the above self-service workflow cannot be completed (for example, you also cannot receive verification codes on your bound email), contact OKX online customer support and submit a support ticket for manual assistance. You will usually need to prepare materials including photos of the front and back of your ID document, a photo of you holding your ID, and screenshots of your recent transaction or deposit records.

FAQ
Q: After modifying my phone number, I cannot withdraw crypto for 24 hours, but can I still trade? Yes. The 24-hour restriction only applies to crypto withdrawals and C2C sell orders, it does not affect spot trading, derivatives trading, or deposit operations. If you want to avoid the restriction window, you can arrange your withdrawal in advance, or finish the phone number binding change during low market volatility periods.
Q: I completed registration with a wrong number that belongs to a stranger, will that person be able to access my account? No. The stranger will only receive a single verification code SMS during the registration process, and cannot log in to your account (since login requires your account password and secondary verification). But we strongly recommend you complete the phone number change process as soon as possible to bind your own accessible number.
Q: Can I directly delete my account and re-register instead? Yes, but you need to note that if there are existing assets in your account, you must withdraw all assets completely before you can submit an account cancellation request. In addition, the cancellation process for verified accounts is more complicated, and your identity information may not be eligible for re-registration after cancellation. If you only entered a wrong number during registration and hold no assets in the account, re-registering directly with a new correct number is a much simpler option.

Next Steps
If you have successfully modified your bound phone number, go to the Security Settings page to check that 3 core security measures are fully configured: Google Authenticator, fund password, and anti-phishing code. The anti-phishing code is especially important: after you set it, all official legitimate emails from OKX will include your custom phrase, any email without this phrase is fake, which can effectively prevent phishing scams.
If you have not finished registration yet and plan to re-register with a new phone number, remember to fill in the invitation code field with 24U2795 (you cannot add the invitation code retroactively after registration is completed).
