When OKX shows "region unavailable" during registration, first confirm one thing: Is the region you selected within OKX's supported service area?

OKX serves over 200 countries and regions, but due to local regulatory requirements, not all regions are eligible for registration. The platform determines service availability based on your IP address and the country/region selected during registration.
Step 1: Verify OKX Supported Regions
OKX's official website explicitly lists which regions are covered and which are not.
How to do it: Go to the OKX website, navigate to the "Help Center" or "Terms of Service," and search for "Supported Countries" or "Restricted Countries." The official documentation will provide the list of restricted regions.
According to public information, since September 2017, OKX has shifted its focus to international markets and ceased promotion and services in mainland China. Its website is inaccessible in mainland China and its app has been removed from local app stores.
Common cause of failure: Many users directly select "China" or "Mainland China" during registration, and the system blocks them immediately. This is not a "registration failure" – the region simply is not within the service coverage.
Completion criteria: You have confirmed whether the region you selected is on OKX's list of supported regions.
Step 2: Distinguish Between "Region Unavailable" and "Compliance Verification Failed"
A "Region Unavailable" notification only indicates that your address/IP is restricted; it may not be the final result. In some cases, it can be resolved through legitimate channels.
Case A: You selected Mainland China. OKX officially withdrew from the mainland China market in 2021 and does not support registration for mainland China users. If you select mainland China, the system will directly prompt that it is unavailable.
Case B: You selected another region, but your IP does not match that region. Certain regions, such as Hong Kong, have specific requirements. In practice, although OKX prohibits selecting Hong Kong as the registration address, some users register with China as the address, verify using a mainland Chinese ID, and can complete registration under a Hong Kong IP. However, this falls into a grey area of platform rule enforcement and carries the risk of future account restrictions.
Case C: You selected an EEA region but want to trade USDT pairs. Based on 2026 reports, OKX no longer supports USDT trading pairs for European Economic Area traders. Even if registration is successful, trading functions may be restricted.
Completion criteria: You clearly understand the service status of the region you selected and any functional limitations that apply to that region.
Step 3: Check Whether You Are Using a VPN or Proxy
Many "region unavailable" alerts are triggered by a VPN. If the VPN node points to a restricted region, the system will block access.
How to do it: Turn off the VPN and access the OKX website or app using your local network. If the notification disappears, the restriction was caused by the VPN node. If you are still blocked after turning it off, your current location itself is not within the service area.
Completion criteria: You have confirmed whether your current network environment is identified as a restricted region.
Risk reminder: If you bypass the system restriction by switching the registration region, during the subsequent KYC verification, your identity documents and proof of address will not match your registered region. Your account will be flagged as "irregular registration" and may face withdrawal freezes or account closure. The platform has very low tolerance for irregular registrations. Do not trust any services that offer "proxy registration" or "help you pass regional verification." Such services often use stolen identities or forged documents; once discovered, the account will be permanently banned.

How to Verify the Operation
If your selected region is indeed within the service coverage and your IP is not blocked, submitting the registration information should allow you to proceed normally to the next step (email or phone verification). If you repeatedly receive a "region unavailable" prompt, it means the selected region is not in the service range, or your network environment has been determined to be a restricted area. It is advisable to stop trying and choose a compliant path. Verification channels: OKX's official "Terms of Service" and "Help Center → Supported Regions" page.
