First Three Steps: Check Spam, SMS Filters, Wait 30 Seconds and Retry

Not receiving the verification code is the most common issue during registration. In most cases, it is not a system failure but due to emails being flagged as spam, SMS being blocked by the phone, or network delays causing timeout.

1. Email Verification Code Not Received: Check Spam Folder First

You need JavaScript enabled to view it.. Major domestic email providers often automatically classify these emails into spam or promotional folders.

Steps:

Log in to your email web client, open folders such as "Spam", "Promotions", and "Subscriptions".
Search for "okx.com" in the search bar to find any missed emails.
If found, click "Not Spam" or "Mark as Normal", and add the sender address to your contact whitelist.

If still not received:

Check if your email storage is full. Clear space and request the verification code again.
Some niche email services may have protocol compatibility issues with OKX's email server. Consider switching toQQ Mail, NetEase Mail, or Outlookto re-register.

2. SMS Verification Code Not Received: Check Blocked Messages

When sending SMS verification codes to +86 phone numbers, some carriers or phone security software may automatically block international messages.

Steps:

Open your phone's SMS app and check folders like "Blocked Messages", "Spam", or "Junk SMS".
If blocked, remove the sender number from the blacklist.
Confirm the phone number is entered correctly: for +86 numbers, remove the leading "0".

Signal or Network Issues:

If the phone signal is unstable, try switching between Wi-Fi and mobile data, or toggle Airplane Mode to reacquire the signal.
The verification code is typically valid for 30 minutes. After 6 incorrect entries, the account may be temporarily locked.

3. Network and Device Issues: Clear Cache, Change Device, Avoid VPN

Clear Browser or App Cache

Old session data cached in the browser may interfere with the verification code request logic:

Chrome: PressCtrl + Shift + Delete(Windows) orCmd + Shift + Delete(Mac), select "All time", check Cookies and cached files, then clear.
App: Go to phone "App Management" → "OKX" → "Storage" → "Clear Cache" (do not select "Clear Data").

Change Platform or Device

If you cannot receive the code on the web version, try requesting it on the app or mobile browser. If it still fails, switch to another device or connect to a different carrier's Wi-Fi network and try again.

Disable VPN or Proxy Tools

Using a VPN may cause the IP location to mismatch with your phone number or email region, triggering risk control limits. Disable VPN and use a local network to retry.

4. Backup Solutions When Verification Code Mechanism Fails

If both email and SMS verification channels are not working, OKX offers the following alternatives:

Scenario	Backup Solution
Email channel failure	Enable OKX Two-Step Verification via the WeChat mini-program "OK Two-Step Verifier" to generate 6-digit dynamic codes as email replacement.
SMS channel failure	Select "Get verification code via voice call" during login; the system will call and read the code aloud.
Cannot receive code for email change	Click "Use other verification method" in the email change process, and use the bound phone number's SMS verification instead.

5. How to Confirm After Completion

After successfully receiving the verification code and completing registration, it is recommended to immediately go to "Security Center" to bind Google Authenticator as a second verification method. This way, even if SMS or email channels fail again, you can log in and operate using dynamic codes.

If all the above steps fail, it may be due to account-level risk control. In the OKX App, go to "My" → "Help & Customer Service", submit your account UID and timestamp of attempts to a human agent. Feedback is typically provided within 1-3 business days.
