How to Register on OKX for Vietnamese Users?
Many Vietnamese users assume that registering on OKX requires depositing in VND or having a local Vietnamese bank account – this is a misconception. The registration itself only requires a Vietnamese phone number that can receive SMS and an ID document. You can decide how to fund your account after registration. The whole process takes about 5 minutes, and the key point is to select "Vietnam" when choosing your nationality.

What You Need Before Registering
Prerequisites:
Phone number: A Vietnamese mobile number from carriers such as Viettel, Vinaphone, or MobiFone that can receive SMS verification codes.
Email: It is recommended to use an international email service like Gmail or Outlook for receiving platform notifications and password recovery.
ID document: Vietnamese Citizen Identity Card (CCCD/CMND) or a valid passport. Ensure the document is within its validity period; when photographing, make sure all four corners are visible and there is no glare.
Internet: OKX's official website and app can be accessed directly from Vietnam without any additional tools.
OKX supports a Vietnamese language interface (you can switch languages in the app settings). If you don't understand English during registration, you can change the language.
Detailed Registration Steps
1. Go to the OKX Official Website or Download the Official App
What to do: Access the OKX platform through official channels to avoid phishing sites.
How to do it:
Desktop: Type the official URL www.okx.com into your browser and make sure the domain is correct before proceeding. Do not enter through search engine ads.
Mobile: iPhone users search for "OKX" in the App Store (requires a Vietnam region account); Android users search for "OKX" on Google Play. The developer shown for both should be "OKX Technology Company Limited".
When is it done: The page loads properly and you can see the "Register" or "Đăng ký" entry point.
2. Click "Register" and Enter Your Phone Number
What to do: Enter the registration page, choose phone number registration, and input your Vietnamese number.
How to do it:
Click the "Register" button at the top right of the page or on the app's home screen.
Choose the "Phone number registration" method.
Select +84 (Vietnam) as the country/region code.
Enter your Vietnamese phone number and click "Get verification code".
Enter the 6-digit SMS verification code you received.
When is it done: The verification code is validated and you proceed to the password setup page.
3. Set Your Login Password
What to do: Set a strong password for your account.
How to do it:
The password must be 8-20 characters long and include uppercase and lowercase letters, numbers, and special characters (such as !@#$%).
Do not use easily guessed combinations like your birthday, parts of your phone number, or sequential numbers (e.g., 12345678).
Confirm the password and submit.
When is it done: The system confirms the password has been set successfully and moves to the next step.
Your login password should not be the same as your email or social media passwords. OKX will never ask for your password in any form.
4. Select Your Country/Region of Residence
What to do: Choose your country of residence from the system prompt.
How to do it:
During registration, a "Which country/region do you live in?" option will appear.
Select "Vietnam - 越南" from the dropdown list.
Confirm and proceed to the next step.
When is it done: The system confirms that the region supports services, and you will be guided to the KYC identity verification process.
You must select Vietnam at this step because subsequent identity verification requires government-issued Vietnamese documents, and fiat trading pairs and payment methods are also based on this setting.
5. Complete Identity Verification (KYC)
What to do: Submit your personal identity information for platform verification. Without completing KYC, functions such as depositing, trading, and withdrawing will be unavailable.
How to do it:
After logging in, the system will automatically guide you to the "Identity Verification" page (you can also find it under "Account - Security Center").
Case A - Verification using Vietnamese ID card (CCCD/CMND):
Fill in your full name (exactly as on the ID) and ID number.
Upload photos of the front and back of your ID card (ensure all four corners are visible, no glare, and text is clear).
Complete face recognition (follow the prompts to blink, turn your head, etc.).
Case B - Verification using a passport:
Fill in your full name (as on your passport) and passport number.
Upload a photo of your passport's personal information page.
Complete face recognition.
When is it done: The system shows "Submission successful" and enters the review status. The review typically completes within 1-3 working days. You will be notified of the result via SMS or email.
Common reasons for failure:
Blurry document photos, glare, or obstructed information.
The filled-in name or ID number does not match the information on the photo.
The document has expired.
Risk reminder: Using someone else's identity information or forged documents will lead to permanent account freezing and inability to withdraw funds once discovered by the platform.
6. Enable Two-Factor Authentication (2FA) – Highly Recommended to Complete Immediately
What to do: Add a second security lock to your account to prevent asset theft due to password leaks.
How to do it:
After logging in, go to "Account Settings" → "Security Center".
Find "Two-factor Authentication (2FA)" and it is recommended to use Google Authenticator or Authy.
Use the authenticator app to scan the QR code and enter the generated 6-digit dynamic code to complete the binding.
Write down the backup recovery codes displayed during the binding process and store them in a safe place (do not save them in your phone's photo album or cloud storage).
When is it done: The security center shows that two-factor authentication has been enabled. You will need to enter the dynamic code for subsequent logins, withdrawals, and security setting changes.
What to Do Next After Registration
After confirming that your registration is successful and your KYC review is passed, you can start operating from the "Assets" page. Vietnamese users usually deposit by purchasing USDT through P2P trading or via third-party payment channels that support Vietnamese Dong (VND). The specific available payment methods are based on what is displayed in real time on the "Buy Crypto" page in the app.
Review waiting time: KYC reviews are usually completed within 1-3 working days. If you do not receive a result within this time frame, contact OKX official customer support (in-app live chat or email) to check the status.

Frequently Asked Questions
Q: What should I do if the system prompts "This phone number is already registered" when registering?
This means the phone number has already been used to register an OKX account. If you registered it yourself, simply click "Log in". If you are sure it was not done by you, contact OKX customer service and do not try to register again with the same number.
Q: Do Vietnamese users have to use a CCCD for KYC? Can I use a passport?
A passport can also be used for verification. The system supports multiple document types; simply choose "Passport" on the verification page. However, it is recommended to use CCCD/CMND first, as the local Vietnamese verification channel usually processes faster.
Q: What if I selected the wrong country code for my phone number during registration?
The country code cannot be changed after registration. If you selected the wrong one (e.g., choosing +86 but your number is actually a Vietnamese number), this account is essentially bound to the wrong phone number and you will not be able to receive verification codes later. It is recommended to directly register a new account using the correct number.
