How to change my phone number on OKX without losing access?

Prerequisites for Phone Number Replacement

1. The original phone number must remain active and capable of receiving SMS verification codes.

2. The new phone number must not be previously registered on any OKX account.

3. Identity verification (KYC) must already be completed on the account.

4. The device used for the operation must be trusted and connected to a secure network environment.

5. Users must retain access to their wallet’s recovery phrase or private key as a fallback measure.

Step-by-Step Process via OKX Mobile App

1. Launch the official OKX Wallet app and log in using your current credentials, biometric authentication, or recovery phrase.

2. Navigate to the bottom-right corner and tap My, then select Account Security.

3. Locate and tap Phone Number under the contact information section.

4. Choose Change Phone Number and enter the verification code sent to the original number.

5. Input the new phone number, request an SMS code, and submit the received six-digit code to finalize the update.

Web-Based Modification Procedure

1. Visit www.okx.com using a desktop browser or supported mobile browser.

2. Log in with your existing account credentials — no third-party extensions required.

3. Click the profile icon in the top-right corner and select Security Center.

4. Under the Contact Information subsection, click Edit next to the current phone number.

5. Complete dual-layer verification: first by confirming ownership of the old number, then by validating the new one via SMS.

Security Protocols During Transition

1. All verification codes expire within three minutes; users must complete each step before timeout.

2. A 24-hour cooldown period may apply if multiple failed attempts occur during the process.

3. Biometric confirmation is enforced for high-risk actions such as initiating a change from an unrecognized IP address.

4. Email verification serves as a mandatory secondary checkpoint when modifying contact details from a new device.

5. System logs record timestamp, geolocation, and user-agent data for every modification attempt.

Frequently Asked Questions

Q: Can I change my phone number if my old SIM is deactivated?Yes, but only after contacting OKX Support and providing verified documentation proving identity and SIM deactivation.

Q: Will changing my phone number affect my wallet address or stored assets?No. Wallet addresses, private keys, and on-chain balances remain completely unchanged.

Q: Is it possible to use a VoIP number as the new contact number?No. OKX explicitly prohibits VoIP, virtual, or landline numbers for security reasons.

Q: What happens if I enter the wrong verification code five times consecutively?The system locks the change request for 120 minutes and requires email-based manual review before retrying.
