OKX KYC identity authentication tutorial (2026 complete process)

At cryptocurrency exchanges, KYC (Know Your Customer) identity verification is an essential process for linking each user to a real identity. Completing KYC not only unlocks more trading features but also enhances your account security level and withdrawal limits. This tutorial will walk you through OKX’s three-tier KYC verification step by step, along with tips for handling common issues.

If you do not have an OKX account yet, we recommend reading the OKX Registration and Account Opening Tutorial first to complete registration.

What Is KYC Identity Verification?

KYC stands for “Know Your Customer” and is a standard identity verification process used across the financial industry. For cryptocurrency exchanges, KYC verification serves several key purposes:

• Regulatory compliance: Regulators around the world require exchanges to verify user identities to prevent money laundering and terrorist financing
• Account security: Once linked to a real identity, a compromised account can be recovered through identity verification
• Feature unlocking: Unverified accounts face significant restrictions on trading limits, withdrawal limits, and more

OKX KYC Verification Levels

OKX’s identity verification is divided into three levels, each unlocking different features and permissions:

Verification Level	Required Documents	Withdrawal Limit (24h)	Unlocked Features
Lv1 Basic	Name, nationality, ID number	10 BTC	Spot trading, basic withdrawals
Lv2 Advanced	ID photos + facial recognition	200 BTC	C2C trading, futures trading, higher withdrawal limits
Lv3 Institutional/Address	Proof of address / institutional documents	500 BTC	Maximum permissions, high-frequency API trading

For most individual users, completing Lv2 verification is sufficient for everyday trading needs.

Step 1: Log In to Your OKX Account

First, open the OKX official website (www.okx.com) or the OKX app, and log in with your username and password. If you have already set up two-factor authentication, you will need to enter the verification code.

Note: Always confirm you are on the official OKX website to avoid phishing sites that could compromise your account. Refer to the OKX Security Settings Checklist for security best practices.

Step 2: Navigate to the Identity Verification Page

On the Web

1. After logging in, click on your avatar in the top right corner
2. Select “Identity Verification” from the dropdown menu
3. The page will display your current verification level and upgrade options

On the App

1. Open the OKX app and tap the avatar in the top left or “Me” at the bottom
2. Find the “Identity Verification” or “KYC Verification” entry
3. View your current verification status

Step 3: Complete Lv1 Basic Verification

The Lv1 verification process is quick and simple, usually taking just a few minutes:

1. Select nationality: Choose your nationality from the dropdown list — this determines the available document types
2. Enter your name: Type in your full name exactly as it appears on your ID document
3. Enter your ID number: Fill in your national ID number, passport number, or other valid document number
4. Confirm and submit: Carefully review all information for accuracy, then click Submit

Lv1 verification is typically auto-reviewed, passing instantly or within a few minutes after submission.

Common Lv1 Issues

• Name format errors: Make sure the name matches your document exactly, including any romanization requirements
• ID number mismatch: Ensure the number matches the selected document type — do not add or omit characters

Step 4: Complete Lv2 Advanced Verification

Lv2 verification requires uploading ID photos and completing facial recognition. This is the most critical verification step.

Preparation

Before starting, have the following ready:

• A valid ID document: National ID (recommended), passport, or driver’s license — ensure it is not expired
• Good lighting: Both photo uploads and facial recognition require adequate lighting
• A stable internet connection: Facial recognition requires real-time video data transmission

Upload ID Photos

1. Select your document type (national ID / passport / driver’s license)
2. Follow the prompts to photograph or upload the front of your document
3. If using a national ID, you also need to upload the back
4. Ensure photos are clear, complete, with all four corners visible and no glare or obstructions

Facial Recognition Verification

1. Enter the facial recognition step and position your face within the on-screen frame
2. Follow the prompts to complete the required actions (blinking, turning your head, opening your mouth, etc.)
3. Keep your face evenly lit and do not wear sunglasses or a hat
4. The system will automatically redirect to the results page once recognition is complete

Lv2 Verification Tips

• ID photo quality: This is the most common reason for verification failure. Avoid the following:

  • Blurry or low-resolution photos
  • Fingers covering the document
  • Glare making information unreadable
  • Screenshots or photos of documents displayed on a screen

• Facial recognition failures: If it fails multiple times, try:

  • Moving to a location with better lighting
  • Removing your glasses
  • Cleaning your phone’s front camera
  • Using the app instead of the web version (the app has a higher success rate)

Step 5: Lv3 Verification (Optional)

Lv3 verification is mainly for high-volume traders or institutional users. Individual users generally do not need to complete this level.

Personal User Address Verification

• You need to provide proof of address issued within the last three months
• Acceptable documents include: bank statements, utility bills, government correspondence, etc.
• The name and address on the document must match your account information

Institutional Verification

• Submit company registration documents, business licenses, etc.
• Provide identification of the legal representative
• Complete an additional due diligence process

Step 6: Check Verification Results

After submitting your verification, you can view the review progress on the identity verification page:

• Lv1: Usually approved instantly, no longer than 24 hours at most
• Lv2: Typically 1-3 business days, possibly up to 5 business days during peak periods
• Lv3: Depending on the complexity of your documents, this may take 5-10 business days

After approval, the system will notify you via in-app message and email. If rejected, the notification will explain the reason and provide suggestions for resubmission.

KYC Differences by Region

Users in different countries and regions may experience variations in the KYC process:

Region	Recommended Document	Special Requirements
Mainland China	National ID	Must complete Lv2 to use C2C
Hong Kong	ID card / passport	May require proof of address
Southeast Asia	Passport / local ID	Some countries require additional review
Europe & Americas	Passport / driver’s license	Typically requires proof of address

Common KYC Failure Reasons and Solutions

Based on user feedback, here are the most common reasons for KYC verification failure:

1. Unclear ID photos: Use a high-resolution camera and ensure natural lighting
2. Expired ID document: Check the expiration date — expired documents cannot pass verification
3. Information mismatch: The name entered in Lv1 must exactly match the document uploaded in Lv2
4. Screenshots used: Screenshots, photocopies, or re-photographed images of documents are not accepted
5. Face does not match ID: Significant differences between the ID photo and your current appearance may cause failure
6. Unstable network: An interruption during facial recognition will cause failure — use a Wi-Fi connection

Summary

While OKX’s KYC identity verification involves several steps, the process is straightforward with proper preparation. New users should complete Lv1 and Lv2 verification as soon as possible after registration to unlock the full trading experience. If you encounter issues during verification, do not worry — carefully review your materials and resubmit.

After completing KYC verification, you can start spot trading on OKX or buy your first cryptocurrency through C2C.

Risk Warning: Protect your personal privacy during the identity verification process. Only submit ID documents through official OKX channels — never share any identity information through third-party links or unofficial customer service. If you notice suspicious activity, contact OKX official customer support immediately.
