Step 1: Before You Submit – Document Checklist
What to do: Before opening the app to submit your application, spend 3 minutes checking your documents to avoid being rejected on the first attempt.
How to do it:
Check document validity: Your ID must be within its validity period. Expired documents are rejected immediately.
Check photo quality: Use your phone's native camera, turn off beauty modes and filters. Make sure all four corners are visible, there is no glare, and the text is clearly readable.
Check information consistency: The name and ID number you enter – including uppercase/lowercase letters in pinyin, spaces, and the "X" at the end of some ID numbers – must match the original document exactly, character by character. Inconsistent information is one of the most common reasons for rejection.
One identity, one account: The system will check whether the same identity information has already been used to register an account. Duplicate registrations will be rejected.
When are you done: You have confirmed that your document is valid, the photos meet the requirements, the information is correct, and no duplicate registration exists.
Lv.1 Basic Verification (information only) is usually completed instantly; Lv.2 Advanced Verification requires uploading ID photos and facial recognition, and the review may take up to 3 days.
Step 2: Troubleshooting After Rejection – Why Was It Rejected
What to do: If your verification is rejected, check the reasons below one by one.
How to do it, compare against these common failure reasons:
| Failure Reason | What It Looks Like | Solution |
|---|---|---|
| Photo does not meet requirements | Blurry, glare, overexposed, corners cut off, edited | Retake: solid background, straight-on shot, no flash |
| Document is invalid | Expired, unsupported document type, no photo of the holder | Use a valid document and make sure you selected the correct document type |
| Information mismatch | Entered name/date of birth/ID number does not match the document | Check every character, especially capitalization of "X" and spaces |
| Facial recognition failed | Wearing glasses/hat, poor lighting, shadows on face | Remove any covering, retry in even lighting |
| ID already verified | The identity information is already linked to another account | Contact customer service with your ID number for verification and resolution |
| Attempt to change verification information | Trying to switch to another person or another document | The platform does not support changing the verified identity; the restriction cannot be lifted |
| Region not supported | Your country/region is not within the service area | Read the Terms of Service to confirm restricted regions |
When are you done: You have identified the specific reason for rejection and corrected it according to the corresponding solution.
The rejection reason is also sent to your registered email. You can click the link in the email to resubmit directly.
Step 3: When the System Triggers Additional Verification – Supplementary KYC and Enhanced Due Diligence
What to do: If your account is asked to complete "Additional Verification" or "Enhanced Due Diligence", understand why and how to proceed.
How to do it:
Why you are being asked: The platform periodically reviews accounts to meet compliance requirements, and some users are randomly selected to update their information. It may also be required to unlock higher trading limits or specific features.
What additional verification includes: You may need to provide proof of address, proof of source of funds and source of wealth, an occupation information questionnaire, etc.
How to operate: Go to the [Identity Verification] page and submit the corresponding documents according to the items requested by the system. If you select the wrong item, you can enter the additional verification page and click [Update Now] to reselect.
Review time: Usually completed within 24 hours after submission. Pay attention to notifications in the User Center.
Requirements for source of wealth/funds documents: Documents must be originals (not screenshots), in color, unedited, with all four corners visible, and the name must match the account holder's name.
When are you done: You have submitted the requested supplementary materials and are waiting for the review result.
If you selected the wrong source of funds item and the review failed, go to the additional verification page and click [Update Now] to reselect, then supplement the corresponding supporting documents and resubmit.
Step 4: Maintenance After Approval – Handling Changes and Expired Documents
What to do: How to handle changes to personal information or expired documents after your verification has been approved.
How to do it:
Situation A: Document expired
Action: Go to the [Identity Verification] page, click [Modify Verification], select the reason "ID expired", re-upload the front and back photos of your new document, and complete facial recognition.
Note: Account functions are not affected during the renewal period, but you must update before the document expires.
Situation B: Name/personal information changed
Action: Also enter through the [Modify Verification] entrance, select the corresponding reason for the change, and upload the new document and proof of change documents.
Limitation: The platform does not support "changing the verified person" or "changing the document type" – once your identity is verified, you cannot change it to someone else's information. If your account is restricted because you tried to change the verified person, the restriction cannot be lifted.
Situation C: Moved to a new country
After logging in, go to the [Identity Verification] page to modify your country of residence. You may need to resubmit a proof of address that meets the requirements of the new region.
When are you done: The information update has been submitted and is awaiting approval.
Step 5: Handling Account Restrictions – Verified but Functions Still Limited
What to do: Cases where your KYC is clearly approved but trading or withdrawal functions are still restricted.
How to do it:
Go to [Security Center] - [Restriction Records] to check the specific type of restriction (prohibited from opening positions, withdrawal restricted, view-only mode, etc.).
Check whether you have completed Lv.2 verification: Some functions require Lv.2 Advanced Verification. Confirm that the identity verification page shows "Verified".
Check whether additional verification has been triggered: Go to the identity verification page and see if there are pending requests for supplementary materials.
Check whether your proof of address matches: If you were asked to submit proof of address, confirm that the name and address on the document match the information in your account, and that the document is dated within the last 3 months.
If everything above checks out normal: Submit a ticket via [Help Center] - [Contact Customer Service], explain your situation, and attach a screenshot of the restriction record.
When are you done: You have identified the reason for the restriction and submitted an appeal, waiting for customer service to process it.
