Changing your registered phone number on a cryptocurrency exchange is a common concern—especially when switching carriers, losing access to an old number, or enhancing account security. If you're an OKX user wondering, “Can I change my bound phone number on OKX?” or “How do I update my phone number if my old one no longer works?”—you're not alone. The good news is that OKX fully supports changing your bound mobile number, provided you meet certain verification requirements.
In this guide, we’ll walk you through the complete process of updating your phone number on OKX, covering both scenarios: when your original number still works and when it doesn’t. We’ll also address key security practices and frequently asked questions to ensure a smooth, secure transition.
👉 Discover how to securely manage your digital assets with confidence.
Why Updating Your Phone Number Matters
Your phone number on OKX isn't just for communication—it plays a critical role in account security. It's used for:
- Two-factor authentication (2FA) during login
- Withdrawal confirmations
- Identity verification and recovery
- Security alerts and risk monitoring
If you no longer have access to your registered number, you may face issues such as:
- Inability to receive SMS codes
- Blocked withdrawals
- Difficulty recovering your account during lockouts
- Delays in resolving security flags
Therefore, keeping your contact information up to date is essential for uninterrupted access and optimal security.
Can You Change Your Phone Number on OKX?
Yes, absolutely. OKX allows users to change their bound phone number at any time, but the method depends on whether you can still verify via your current number.
There are two primary scenarios:
- Your old phone number is still active – You can change it directly in settings.
- Your old number is no longer usable – You must go through an identity verification appeal process.
Let’s explore both in detail.
Scenario 1: Old Number Still Works (Recommended & Fastest Method)
If your original phone can still receive SMS, updating your number is quick and straightforward.
Step-by-Step Guide
- Log in to Your OKX Account
Use your current credentials—either SMS verification or Google Authenticator. - Navigate to Security Settings
Go to:
Account Settings → Security → Phone Verification - Select “Change Phone Number”
Click the option to update your mobile number. Verify Your Identity
OKX will ask for:- A verification code sent to your old number
- A second factor (Google Authenticator or email code)
- Enter and Confirm New Number
Input your new mobile number, request a code, and confirm it.
✅ Done! The change takes effect immediately. Your old number is deactivated, and all future verification messages will go to your new number.

Scenario 2: Original Number No Longer Accessible
If you’ve lost access to your old SIM card or deactivated the number, you can’t complete standard SMS verification. In this case, OKX requires a manual identity verification process.
How to Recover Access and Change Your Number
Step 1: Initiate Account Recovery
On the login page, click “Can’t receive verification code?” or look for the account recovery option. This starts the identity appeal process.
Step 2: Submit Required Documentation
You’ll need to provide proof of identity and ownership. Commonly accepted documents include:
- A clear photo of your government-issued ID (passport, national ID, etc.)
A selfie holding your ID, along with:
- Your OKX account UID
- The current date written on a piece of paper
- Proof of alternative verification methods (e.g., Google Authenticator setup)
- Details about recent login activity (device type, IP location, timestamps)
⚠️ Accuracy matters. Ensure all information matches what’s on file with OKX.
Step 3: Wait for Manual Review
OKX’s support team typically reviews submissions within 24 hours. During high-volume periods, it may take slightly longer.
Once approved, you’ll regain control of your account and be able to:
- Remove the old phone binding
- Register a new number
- Re-enable full security features
Frequently Asked Questions (FAQ)
Q1: Will changing my phone number affect my funds or trading history?
No. Your assets, transaction records, open orders, and trading history remain completely unchanged. Only the contact method for verification is updated.
Q2: How long does the phone number change take to生效?
Changes are instantaneous. As soon as the new number is verified, the old one stops working for authentication purposes.
Q3: What if both my phone and email are no longer accessible?
You can still recover your account using Google Authenticator and identity documents. However, the process becomes more rigorous. Always keep at least one reliable recovery method active.
Q4: Is there a limit to how often I can change my number?
OKX does not publish a fixed limit, but frequent changes may trigger additional security checks to prevent unauthorized access.
Q5: Can I use a virtual or VoIP number?
Generally, no. OKX prefers real mobile numbers from recognized carriers for stronger fraud prevention.
Q6: Do I need KYC to change my phone number?
Not necessarily—if you’re using standard verification methods. However, if you're submitting an appeal due to lost access, having completed KYC significantly speeds up the review process.
Best Practices for Account Security After Changing Your Number
After updating your phone number, take these steps to reinforce your account protection:
- ✅ Enable Google Authenticator for 2FA (more secure than SMS)
- ✅ Set up a strong fund password for withdrawals
- ✅ Activate the withdrawal whitelist to restrict transfers to approved addresses
- ✅ Add a backup email address and verify it
- ✅ Regularly review login history and active sessions
These layers of defense reduce the risk of unauthorized access—even if your phone number is compromised in the future.
👉 Enhance your crypto security with next-generation tools and features.
Final Thoughts
Yes, you can change your bound phone number on OKX, whether your old number still works or not. With proper verification methods in place—like Google Authenticator or verified email—you maintain control over your account even during transitions.
The key is preparation: always keep at least one recovery method active, complete KYC early, and avoid relying solely on SMS-based authentication.
By following the steps outlined above, you can confidently update your contact information while keeping your digital assets safe and accessible. Remember to use trusted access points when managing sensitive settings—and consider using secure platforms like OKX that prioritize user safety and transparency.
Stay proactive, stay secure.
