Important注意事项 (Notes & Best Practices)

While changing your phone number is simple, overlooking key details can lead to lockouts or security risks. Follow these expert tips:

🔹 Use an Active Number Only
Ensure your new number is active and under your control. Losing access could complicate account recovery.

🔹 Avoid Public Wi-Fi During Changes
Always perform sensitive operations like this on a private, secure network to reduce interception risks.

🔹 Update Linked Services
If you use third-party apps or wallets connected to OKX (e.g., trading bots, portfolio trackers), update your contact info there too.

🔹 Keep Old SIM Until Confirmed
Don’t discard or deactivate your old SIM card until you’ve fully confirmed the new number works with OKX.

🔹 Enable Alternative 2FA Methods
Relying solely on SMS 2FA is less secure. Consider switching to Google Authenticator or hardware keys for stronger protection.

Frequently Asked Questions (FAQ)

Q1: Can I change my phone number without ID verification?

No. For security reasons, OKX requires identity verification—such as uploading a valid ID document—before allowing any change to your registered phone number.

Q2: How long does it take to change my phone number?

The entire process typically takes under 15 minutes, assuming all documents are valid and your new number receives SMS promptly. Delays may occur if manual review is needed.

Note: Some virtual numbers (e.g., VoIP) aren't supported by OKX for security reasons.

Q4: Will changing my phone number affect my funds?

No. Updating your phone number does not impact your wallet balances, open orders, or trading capabilities. It only updates contact and authentication settings.

Not immediately. Once a number is unlinked, there may be a cooling-off period before it can be used to register or link to another account, depending on regional policies.

Q6: Is it safe to change my phone number on OKX?

Yes—as long as you follow official procedures and never share verification codes or ID documents with anyone claiming to be “support.” Always access OKX through the official site or app.
