1. Complete LV3 advanced video certification

LV3 certification is the highest level of identity verification on the Ouyi platform. It requires a real-time video connection to be verified by a manual auditor for identity authenticity and willingness. This step cannot be skipped and must be completed within the Ouyi App.

1. Make sure that you have successfully passed LV2 certification and the account status is "Pending Video Verification";

2. Open the Ouyi App and enter [Personal Information and Settings] → [Security Center] → [KYC Verification];

3. Click [Start LV3 Video Authentication], and the system will automatically detect the device camera, microphone permissions and network quality;

4. Follow the prompts to adjust your sitting posture and lighting to keep your face fully in the mirror and the background simple and unobstructed;

5. Face the camera and read the randomly generated four-digit numbers on the screen. Do not pause, repeat, or use the electronic screen to display the content during the entire process;

6. Wait for manual review after submission. Feedback is usually completed within 2 hours . If it fails, the specific rejection code will be displayed.

2. Rejection due to non-compliance in data shooting

The system's AI preliminary screening will automatically compare document edge integrity, text readability and portrait consistency. Slight reflections, fingers blocking the ID number, or the ID card being cropped all trigger immediate rejection.

1. Use a pure white or light gray background wall, turn off the flash, and use natural side light to present a three-dimensional look on the face;

2. Lay the ID card flat on dark velvet to avoid interference from glass reflection or table texture;

3. In the selfie, both ears, forehead and complete chin must be exposed, and the hairline must not be covered by bangs;

4. If the validity period of the certificate is less than 90 days, it will not pass the review ;

5. Residents of Hong Kong, Macao and Taiwan should use the Mainland Travel Permit for Hong Kong and Macao residents and cannot upload their residence permit instead.

3. Address proof documents do not match

The system verifies whether the name and address fields in the address certificate are completely consistent with the registration information. If there is one character difference, it will be deemed invalid. Utility bills, bank statements, etc. must contain the official seal or electronic signature of the issuing institution.

1. Select bills issued within the past 90 days , and the PDF printout must retain the original header and footer;

2. The billing address must be word-for-word identical to the resident address filled in in KYC, including the order of "province/city/district/road/number";

3. If a rental contract is used, the front and back of the landlord’s ID card and the key pages of the real estate certificate must be attached as well as the signature pages of both parties;

4. Electronic bills need to be downloaded as original PDF, screenshots or web page save formats are not accepted;

5. The English address proof must be uploaded simultaneously with a Chinese translation stamped by a notary office.

4. Multi-device/IP association triggers risk control interception

The system continuously tracks device fingerprints, WiFi MAC addresses and login behavior sequences. If you have logged into a high-risk account under the same IP, or switched to more than 3 devices within 72 hours, the authentication entrance will be frozen directly.

1. Use your commonly used mobile phone throughout the authentication process, and do not connect to public hotspots or shared networks;

2. Uninstall all unofficial cryptocurrency apps to prevent cross-reporting of SDK data;

3. If you have lent your mobile phone to others to log in to the exchange, you need to wait for a cooling-off period of 7 natural days ;

4. Android users need to turn off the USB debugging and simulated location functions in "Developer Options";

5. iOS users need to turn off "Significant Locations" in [Settings] → [Privacy and Security] → [Location Services].

5. No response after submission or the same materials are returned repeatedly

The system sets a three-level circuit breaker mechanism for repeated submissions of the same incorrect materials. The first return can be modified and retransmitted, the second return will lock the certificate type for 24 hours, and the third return will permanently disable the authentication channel.

1. After receiving the rejection notice, immediately check the "Rejection Reason Code" in the background. For example, "ERR-702" corresponds to a vague signature;

2. Delete the original uploaded file, re-photograph and name the new file "LV3_ID card_20260416_v2";

3. Before uploading, use the "zoom in" function of the photo album that comes with your phone to confirm that every text is clearly legible;

4. If the "ERR-999" unknown error occurs twice in a row, you need to contact Ouyi online customer service to obtain an exclusive reset link;

5. The interval between each resubmission shall not be less than 15 minutes to avoid triggering frequency limits.
