How to Fill in Country/Region and International Dialing Code for Mainland China Users When Registering on OKX?
In the OKX registration page's "Country/Region" dropdown, directly select "China" (China), and the system will automatically switch the international dialing code to +86. Then simply enter your 11-digit mainland China mobile number in the phone number input field.
Below is a step-by-step breakdown.
1. Go to the Registration Page and Find the Phone Number Section
Open the OKX official website or app and click "Sign Up". Under the mobile phone registration option, you will see a dropdown featuring a flag or country abbreviation (such as +86). This dropdown is where you set the dialing code.
2. Select Country/Region: China
Click the dropdown and find "China" or "中国". After selecting it, the preceding international dialing code will automatically change to +86. At this point, the dialing code is correctly filled in. Do not manually enter "+86" before the phone number; you must complete this step by selecting the country.
After selecting "China", the subsequent KYC identity verification will also require submitting a mainland China resident ID card, and the region information must remain consistent.
3. Correctly Enter Your Mainland China Mobile Number
Mainland China mobile numbers consist of 11 digits, usually starting with 1. In the phone number input field, simply enter these 11 digits directly, without adding any spaces, dashes, or a leading 0.
4. Get the Verification Code and Complete Registration
After entering the number, click "Get Verification Code". The code will usually be sent to your phone via SMS within seconds. If your phone can receive the message normally, it means both the country and the number are correct. Enter the verification code, set a login password (8-20 characters; it is recommended to include uppercase and lowercase letters, numbers, and special symbols), check the box to agree to the Terms of Service, and click Sign Up to finish.
Key Prerequisites and Risk Warning
Before starting the registration, confirm two points:
Mobile phone status: Make sure your mainland China mobile number can currently receive SMS normally. If you do not receive the verification code, check whether SMS interception is enabled on your phone, or wait 1–2 minutes before trying to resend.
Compliance risk: According to public information, OKX announced its withdrawal from the mainland China market in 2021. Its website cannot be directly accessed in mainland China, and the app has been removed from domestic app stores. Although the platform still supports mainland China mobile numbers (+86) and ID card verification during registration and KYC, conducting cryptocurrency transactions through this platform as a mainland China resident is effectively within the scope expressly prohibited by regulatory policies, posing significant compliance and financial risks. Please fully understand and assume the corresponding risks yourself.
Common Reasons for Failure
Not receiving the SMS verification code: The most common situation. First check the junk/spam SMS folder; confirm that the mobile signal is normal; if you are using a number from one of the three major domestic carriers, there may occasionally be delays in the international SMS channel – wait 1–2 minutes and then click "Resend".
Network access issues: Due to policy reasons, the OKX official website may not be directly accessible in mainland China. You need to use a compliant network environment to open the registration page.
Confirmation of Completion
The most direct standard of successful registration: successfully log in once with the newly registered mobile number and password and see the account overview page, indicating the account has been created.
Next, the system will guide you to complete identity verification (KYC). This step is mandatory; otherwise, you cannot trade or withdraw funds. During verification, select "China" for the country/region of residence, then submit front and back photos of your ID card and complete facial recognition. Basic verification review typically takes 1–24 hours.
