How to Fill in Country/Region and International Area Code for Thai Users Registering on OKX?
When Thai users register on OKX, select "Thailand" as the country/region and "+66" as the international area code, and both must be consistent. This is the foundation for account compliance verification.
Prerequisites: Confirm Your Thai Phone Number and ID Document Type
Before registering, Thai users should confirm that the following materials and information are ready:
Thai phone number: A Thai number under your own name that can receive international SMS verification codes (area code +66)
Email address: An email account that can receive messages normally (Gmail, Outlook, QQ Mail, etc.)
Identity document: Thai National ID Card (most commonly used and recommended), passport, or driver's license
Step 1: Select the Correct Country/Region on the Registration Page
What to do: After entering the OKX registration page, select your country of residence from the dropdown menu.
How to do it:
Open the OKX official website www.okx.com or the OKX App, and click [Sign Up]
In the "Country/Region" dropdown menu, search for and select "Thailand"
Read and agree to OKX's Terms of Service and Privacy Policy Statement, then click Continue
What counts as completed: The country/region field on the page displays "Thailand".
⚠️ Difference between nationality and residence: OKX restricts based on "Country/Region of Residence", not nationality. For example, users with Chinese nationality but residing in Thailand can select China as nationality and Thailand as country of residence.
Step 2: Enter Your Thai Phone Number and Select the +66 Area Code
What to do: In the phone number input field, confirm that the area code is set to Thailand (+66).
How to do it:
In the phone number input area, locate the area code dropdown menu
Search for "Thailand" and select +66
Enter your Thai phone number (remove the leading 0 from the area code; e.g., 081-xxx-xxxx should be entered as 81xxx-xxxx)
Click [Get Verification Code] and enter the SMS verification code you receive
What counts as completed: The area code displays "+66", the phone number can receive the verification code normally, and the code is successfully verified.
⚠️ Country/Region and area code must be consistent: If your country of residence is set to Thailand, the area code must be +66. A mismatch will cause your KYC verification to be rejected.
Step 3: Complete Registration and Proceed to Identity Verification (KYC)
What to do: After registration, you must complete identity verification to unlock core features such as trading, deposits, and withdrawals.
How to do it:
Log in to your OKX account and go to [Profile] → [Identity Verification]
Select Country/Region: Confirm again and select "Thailand"
Select document type: It is recommended to use the Thai National ID Card (most commonly used). A passport or driver's license may also be used
Take and upload photos of the front and back of your identity document (ensure clarity, no glare, and complete information visible)
Complete facial recognition (follow the on-screen prompts, such as "blink" or "turn your head")
Submit for review, which typically takes anywhere from a few minutes to 24 hours
What counts as completed: The identity verification status shows "Verified".
Step 4 (Recommended): Configure Security Settings
What to do: After registration and KYC completion, enable security protection.
How to do it:
In [Security Settings], bind Google Authenticator, which is more secure than SMS verification
Set an Anti-Phishing Code to help identify official OKX emails
Back up the recovery key generated when binding Google Authenticator, and store it offline in a secure location
What counts as completed: 2FA is bound, and the recovery key is backed up.
Common Reasons for Failure
Country/Region set to Thailand but area code selected for another country (e.g., +86) — Inconsistent information may lead to KYC verification rejection.
Unclear photos of identity documents — Blurry document information, glare, or cropped edges will result in system rejection. Ensure photos are taken in a well-lit environment.
Not checking the reason after KYC rejection — After a rejection, check the email or app notification for the specific reason (usually unclear photos or mismatched information), and resubmit accordingly.
Using a VPN to switch to another region during registration — If the IP address shows a different country but Thailand is entered, it may trigger risk control and require additional verification.
Risk Reminder
Always download the app from the official website www.okx.com or official app stores, and beware of counterfeit websites and phishing links.
Never disclose your password, verification codes, private keys, or seed phrases to anyone. OKX officials will never proactively ask for this information.
According to Thai regulatory requirements, the features and services available to Thai users on OKX may differ. Please refer to what is displayed on the platform for accurate information.
How to Confirm You Have Filled in Everything Correctly
Log in to your OKX account and go to [Profile] → [Security Settings] to check:
Country/Region displays as "Thailand"
Phone number area code displays as "+66"
Identity verification status displays as "Verified"
If all three items above are confirmed, your account has completed the basic setup and you can begin using the trading features.
