How to Complete OKX Level 3 KYC Verification? Highest Level Verification Guide
Level 3 verification is the highest tier of personal identity verification on OKX. Its core requirement is a real-time video call with a human reviewer—no simple selfie or blink recognition, and no workaround exists. After completing the video check in the App, the system typically returns a result within 2 hours. Approval grants high transaction limits and is also a mandatory prerequisite for applying to become an OKX certified merchant or a contract lead trader.
What to Prepare Before Verification
Prerequisites:
You must have passed Level 2 verification and your account status shows "Pending Video Verification" or "Upgrade to Level 3". If you cannot find the entry, confirm that Level 2 verification is complete.
Install the latest version of the OKX App (v7.8.0 or above). The video call feature for Level 3 verification is only supported on the App.
Prepare a valid identity document that matches the one used for Level 1 and Level 2 verification. For users in mainland China, only the Resident Identity Card is accepted. For users in other regions, follow the system requirements displayed.
Prepare proof of address (submit if prompted by the system): utility bills, bank statements, etc., issued within the last 90 days, showing your name and residential address clearly, and matching your registration information exactly.
Choose a quiet, well-lit environment in advance. During the video call, you will need to read out random digits aloud. Background noise or poor lighting will affect the pass rate.
Ensure a stable internet connection. The video call requires real-time transmission; Wi-Fi or 5G network is preferred.
Level 3 verification is conducted by human reviewers. During peak periods, the waiting time may extend to 1–3 days. There is no way to skip or expedite it automatically.
Step-by-Step Instructions for Level 3 Verification
1. Enter the Level 3 Verification Entry
Goal: Navigate to the Level 3 verification start page in the App.
Path:
Open the OKX App, tap the bottom-right [My] → select [Security Center].
Find and tap [Identity Verification].
In the list of verification levels, tap the [Verify Now] or [Upgrade] button next to Level 3.
Completion indicator: The page displays an explanation of "LV3 Advanced Video Verification", clearly stating that a real-time video call is required.
If you cannot find the Level 3 verification entry on the Identity Verification page, it means your Level 2 verification may not have been approved, or Level 3 verification is not supported in your account's region.
2. Confirm or Update Personal Information
Goal: Verify and supplement the information required by the system.
Path:
Confirm that your name, ID number, and date of birth match the document you hold exactly.
If required by the system, fill in or update your residential address, which must exactly match the content of the proof of address you will subsequently submit.
If prompted to submit proof of address, have a compliant bill document from the last 90 days ready in advance.
Completion indicator: All required fields are filled in, and you automatically enter the video verification queue.
3. Start the Video Call and Face Verification
Goal: Have your identity verified remotely by a human reviewer through a live video link.
Path:
Tap [Start LV3 Video Verification]. The system will automatically check camera and microphone permissions, as well as network quality.
Follow the prompts to adjust your posture and lighting. Keep your entire face in the frame against a clean, unobstructed background.
Look into the camera and read aloud the random four-digit number shown on the screen. Do not pause, repeat, or use an electronic screen to display the content.
Follow the reviewer's instructions to complete simple actions such as nodding or turning your head.
Completion indicator: The video call ends and the system displays "Submitted successfully, pending review".
Do not interrupt or exit the video verification process, otherwise you will need to re-queue. If the first attempt fails, wait at least 15 minutes before trying again to avoid triggering frequency limits.
4. Upload Proof of Address (If Required by the System)
Goal: Submit a compliant proof of address document. Some users who already submitted this during Level 2 verification do not need to submit again.
Path:
Upload a utility bill, bank statement, or government letter issued within the last 90 days. The document must include the issuing institution's official seal or electronic signature.
The billing address must match the residential address you filled in for KYC character by character, including the order of province/city/district/road/number.
PDF or JPG formats are acceptable. Screenshots or temporarily saved web page files are generally not accepted.
Completion indicator: All files are uploaded, tap submit to enter the manual review queue.
5. Wait for the Manual Review Result
Goal: Wait for the system to complete the manual review and receive the result.
Path:
After submission, the system enters the review queue. Results are usually provided within 2 hours, but may extend to 3 business days during peak periods.
You will be notified of approval or rejection via SMS or email.
You can check the real-time review status on the [Identity Verification] page in the App.
Completion indicator: The page status updates to "Level 3 Verified".
Common Failure Reasons and Solutions
| Failure Type | Specific Reason | Solution |
|---|---|---|
| Video verification failed | Unclear digit reading, improper movements, cluttered background, insufficient lighting | Adjust environment and equipment, then retry after 15 minutes |
| Non-compliant ID document | Blurry photo, incomplete four corners, less than 90 days until expiry | Re-photograph, ensuring all conditions are met before resubmitting |
| Proof of address mismatch | Bill is older than 90 days, name/address inconsistent with registration information | Update with a bill from the last 90 days, verify address character by character |
| Device/network issue | Camera or microphone permission not enabled, network quality substandard | Check permission settings, switch to Wi-Fi or 5G network |
| Resubmitting the same material | Re-uploading a rejected file without making changes | Review the rejection reason, correct as instructed, then resubmit |
Risk Reminders:
Information submitted for Level 3 verification cannot be modified or revoked on your own. Confirm all information is accurate before submitting.
If you submit the same incorrect material twice in a row, the system may lock that document type for 24 hours; a third time will permanently disable that verification channel.
Using another person's identity information or forged documents for verification will result in permanent account freezing.
Next Steps After Level 3 Verification
Once you confirm the status on the [Identity Verification] page in the App has updated to "Level 3 Verified", you will enjoy the highest tier of withdrawal limits and trading permissions.
If you plan to apply to become an OKX certified merchant (P2P trading market maker), Level 3 verification is one of the mandatory thresholds. You must also meet conditions such as an order completion rate not lower than 90% and a 10,000 USDT deposit in your funding account. If you plan to become a contract lead trader, in addition to Level 3 verification, you must submit a record of no fewer than 50 live contract trades from the last 90 days.
