How Hong Kong Users Should Fill In Country/Region and International Area Code When Registering on OKX

OKX

19 July 2026

Direct conclusion: OKX's registration page does not have the option 'Hong Kong, China'. According to the licensing requirements of the Hong Kong Securities and Futures Commission, OKX has not obtained a Hong Kong license and cannot provide services to Hong Kong residents. When registering, select 'China' as the country/region, choose +86 as the international area code, and complete KYC using a mainland Chinese ID card. This is the currently workable registration method for Hong Kong users.

1. Understanding the Background: Why There Is No Hong Kong Option

First, understand OKX's policy toward Hong Kong, and you will know what to select.

Key points:

OKX once applied for a Hong Kong virtual asset trading platform license but eventually withdrew the application due to relevant restrictions.
Since May 2024, OKX has ceased offering virtual asset trading-related services in Hong Kong.
Actual testing shows: Although OKX prohibits selecting 'Hong Kong' as the registration address, users can choose 'China' as the address to register, support verification with a mainland Chinese ID card, and can complete the registration using a Hong Kong IP address.

Understanding that the absence of a Hong Kong option is due to compliance reasons and not a technical fault, selecting 'China' is the currently viable registration path.

For Hong Kong identity card holders registering on OKX, the currently workable method is: select 'China' as the country/region and use a mainland Chinese ID card to complete KYC. If a mainland Chinese ID card cannot be provided, normal registration is not possible.

2. Filling In Country/Region

On the registration page, find and select the correct option in the country/region drop-down list.

Steps:

Go to the official OKX registration page.
In the 'Country/Region' drop-down list, select 【China】 — note it is not 'Hong Kong, China'.
If the list contains 'China' but not 'Hong Kong', directly choose 'China'.

Completion standard: The country/region field on the page displays 'China'.

Common reasons for failure:

Selecting 'Hong Kong, China': This option does not exist on OKX's registration page. If some third-party tutorials claim that 'Hong Kong, China' can be selected, that is inaccurate; the OKX official page has removed this option.
Selecting another country: If a region other than China is chosen, the subsequent KYC will require identity documents from that corresponding region, and neither a Hong Kong ID card nor a mainland Chinese ID card will match.

3. Filling In International Area Code and Mobile Number

In the mobile number input area, choose the correct international area code and enter your mobile number.

Steps:

In the area code drop-down list on the left side of the mobile number input box, select +86.
Enter your mobile number:
- If you have a mainland Chinese mobile number: directly enter the 11-digit mainland number.
- If you only have a Hong Kong mobile number (+852): some users have reported that +852 numbers can also receive verification codes, but it is recommended to prioritize a +86 number, because the selected region during registration is 'China', and the system may default to +86.
Click to get the verification code, then enter the received SMS verification code to complete verification.

Completion standard: Receive the SMS verification code and successfully enter it; the page shows 'Verified'.

Note: The Hong Kong international area code is +852, but when the registration region is 'China', whether selecting +852 as the area code will always work is uncertain. The safest method is to use a +86 mainland Chinese mobile number.

4. Completing KYC Identity Verification

After registration, you must complete identity verification (KYC) to use trading functions.

Steps:

Go to 【Personal Center】 → 【Identity Verification】.
Select 'China' as the country/region — keep it consistent with the registration choice.
Upload photos of the front and back of your mainland Chinese ID card, and complete the face recognition as required.
Submit and wait for review; usually it takes 1–3 working days.

Completion standard: The system displays 'Verification Passed' or 'Verified'.

Risk reminders:

Compliance risk: This is the current operational practice within the industry, but OKX's terms of service and regional restrictions may be adjusted at any time.
Account risk: If the platform strengthens regional compliance checks in the future, accounts registered with a 'China' identity but actually residing in Hong Kong may face restrictions.
Identity document matching: When the registration region is 'China', KYC must use a mainland Chinese ID card; a Hong Kong ID card cannot be used.

How to confirm you have filled in correctly?

On the registration page, the country/region shows 'China', the mobile number area code is +86 (or +852) and you successfully receive the verification code — if these two items are filled in correctly, you can proceed with the registration process. After using a mainland Chinese ID card to complete KYC verification and passing the review, the account will be opened. If you encounter a region restriction prompt during registration, check whether you have mistakenly selected 'Hong Kong' or another region without service.
