What should I do if I cannot receive the mobile verification code when logging in?

If you cannot receive the phone verification code when you log in to your account, try the following solutions:

1. Choose to receive the code via a call instead of an SMS.

2. Double-check whether the linked email account received an email from OKX containing a verification code.

3. Check whether your phone is connected to a stable network.

4. If your phone has not been turned off for a while, turn off the device and restart it. Then check if you have received a message containing the verification code.

5. If you use a dual-SIM mobile phone, try switching the two SIM cards.

6. Check if your inbox is full and delete some emails to free up space.

7. Check whether your phone has applications that may automatically intercept text messages.

8. Multiple requests for the verification code could cause a sending failure. We recommend waiting 2 hours before trying again.

9. Try unlinking and linking your phone number. To do so, you must prepare the email address linked to your current OKX account, a valid ID, and a video for identity verification. We will complete the review within 1 hour. Please ensure you remain reachable during this period. If you unlink your phone number, note that you cannot perform withdrawals within 24 hours after the successful reset.

10. If it still doesn’t work after trying all the methods above, you can head to the support center and contact our customer service through the chatbot.
