Updating your contact details, such as your phone number, is a straightforward process designed to keep your account secure and accessible. Whether you’ve changed your service provider, lost access to your old number, or simply wish to use a different mobile number, the steps are simple and can be completed via the app or website.
It is important to ensure your account information is current to maintain seamless access to all features and to receive important security notifications.
Using the Self-Service Tool
The quickest way to update your phone number is by using the self-service feature within your account settings. This method requires you to be logged in and have access to your current authentication methods.
If you encounter any issues during the process, guidance is available to help you complete the verification steps.
If You Can Log In to Your Account
Via the Mobile App
Follow these steps to change your number directly from your smartphone:
- Open the OKX app and navigate to your User Center.
- Select Profile and Settings, then proceed to the Security section. Under Authentication Methods, choose Phone.
- Tap on Change Phone Number. Enter your new number in the New Phone Number field.
- Select Send Code for both the Current Phone Number SMS Code and the New Phone Number SMS Code fields. A 6-digit verification code will be sent to both numbers.
- Enter the two received SMS codes.
- Complete the process by entering your two-factor authentication (2FA) code when prompted.
Note: If you cannot complete the verification, select the Cannot Verify option at the bottom of the page for alternative instructions.
You will receive a confirmation email or SMS once your phone number has been successfully updated. For a visual guide through these security settings, you can view detailed instructions here.
Via the Website
The process on the web platform is very similar:
- Go to your Profile and select the security settings.
- Find the Phone Authentication option and select it.
- Choose your country code and input your new number in the New Phone Number field.
- Click Send Code for both verification fields. Enter the two 6-digit codes sent to your current and new phone numbers.
- Provide your 2FA code to finalize the change.
Note: The Cannot Verify option is available if you run into any problems during this step.
A confirmation message will be sent to you upon successful completion of the process.
If You Cannot Log In to Your Account
If you have lost access to your account and your registered phone number, you still have options. You can dissociate the old number directly from the two-step verification login page by following the provided recovery prompts.
Alternatively, you can contact customer support for assistance. The support team can guide you through the necessary identity verification steps to reset your phone number and regain access to your account.
Important Security Notice
For your protection, certain account functions will be temporarily restricted after changing your phone number. Specifically, you will not be permitted to process withdrawals or use the P2P trading platform to sell cryptocurrencies for a 24-hour period. This security cool-down period helps ensure that any changes to your account are legitimate and protects your assets.
Frequently Asked Questions
Why can’t I make withdrawals immediately after changing my number?
This is a standard security measure. The 24-hour hold on withdrawals and P2P selling is placed to prevent unauthorized transactions in case your account was compromised. It allows you time to verify the change and report any suspicious activity.
What should I do if I don’t receive the SMS verification code?
First, ensure your phone has a strong signal and that you have entered the number correctly. If you still don’t receive it, use the Cannot Verify option on the verification page to be guided through an alternative method, which may involve using email verification or contacting support.
I lost access to my old number and can’t log in. How do I recover my account?
You can start the account recovery process from the login page by selecting the option for two-step verification issues. You will need to verify your identity through other means, such as your email address. For direct help, explore more strategies available through customer support.
Can I use a virtual phone number for verification?
It is recommended to use a personal, permanent mobile number for account verification. Some virtual numbers or VOIP services may not reliably receive SMS codes, which could lock you out of your account during critical security steps.
Is there a limit to how often I can change my phone number?
While there may not be a strict public limit, frequent changes to your primary phone number can trigger additional security reviews to prevent fraudulent activity. It is best to only update your number when necessary.
What other security settings should I update?
After changing your phone number, it is a good practice to review all your security settings. Ensure your two-factor authentication is active and that your registered email address is also up to date to maintain multiple recovery options.
