Can I Use a Mainland Chinese ID for OKX KYC?
Yes. OKX clearly supports Mainland Chinese residents using a second-generation ID card to complete KYC identity verification. According to multiple verification guides and actual tests, when Mainland Chinese users select "China" as the country/region during registration, the system defaults to the ID card as the primary document type. Simply upload the front and back photos as required and complete the face recognition.

Prerequisites
Before using a mainland ID for KYC, check these three things:
The ID card is within its validity period – Expired or cards with less than 3 months until expiry will be rejected during the initial review.
The ID card is a second-generation resident ID card – First-generation ID cards or temporary ID cards are not accepted.
Your current network environment can access the OKX platform normally – Access may be restricted under some network conditions; operate through compliant channels.
Step 1: Confirm the ID Card Meets Platform Requirements
What to do: Before starting verification, check your ID card against the platform's basic conditions.
How to do it, item by item:
| Check Item | Requirement |
|---|---|
| Document Type | Only second-generation resident ID cards are accepted; temporary or paper-based documents are not accepted. |
| Document Status | Must be within validity period; remaining validity should ideally be 3 months or more. |
| Photo Source | Must be a photo of the original card; screenshots, photographs of photographs, or photocopies are not accepted. |
| Photo Clarity | All four corners must be fully visible, no glare, no obstructions, text clearly legible. |
| Format Requirements | Upload front and back separately; stitched or cropped images are not accepted. |
When is this step considered complete: When you have confirmed that the ID card you hold meets all the above conditions.
KYC standards on OKX vary by region. Mainland Chinese users can only use the ID card as the primary verification document; it is not possible to switch to a passport or driver's license during the verification process. The system automatically matches the document type based on the country/region you select during registration.
Step 2: Select Document Type and Upload on the Identity Verification Page
What to do: Log into the OKX App, enter the identity verification process, and upload the front and back of your ID card as prompted.
How to do it:
Open the OKX App, tap the [User Center] icon in the top left of the home page → [Profile and Settings] → [Profile] → [Identity Verification].
Tap [Verify Now]; on the "Select Document Type" screen, Mainland Chinese users will only see the ID Card option (the system fixes it and it cannot be manually changed).
Fill in Lv.1 Basic Information: your true Chinese name exactly as on the ID card, and the 18-digit ID number (the last digit X must be uppercase).
Lv.2 Advanced Verification: Upload the front (national emblem side) and back (portrait side) of the ID card in sequence, ensuring all four corners are visible and there is no glare.
Complete face recognition: remove masks, hats, and dark glasses; in a well-lit indoor environment, follow the prompts to blink, turn your head, open your mouth, etc.
When is this step considered complete: The ID photos are successfully uploaded, face recognition is passed, and the page enters the review stage.
Step 3: Wait for Review and Pay Attention to Result Notifications
What to do: After submission, wait for the OKX review team to process; mainland ID card verification usually uses a dual-track AI + manual review mechanism.
How to do it:
Lv.1 Basic Verification (information only, no document photo): the system verifies in real time, usually returning a result within 30 seconds.
Lv.2 Advanced Verification (document upload + face recognition): automatic initial review usually completes within a few minutes; complex cases are transferred to manual review, with a maximum of 24 hours.
After approval, you will receive a notification in the app and at your registered email address, and account functions will unlock according to the corresponding level.
If not approved, the page will show the reason for rejection (e.g., blurry photo, information mismatch). Correct the issue as prompted and resubmit.
When is this step considered complete: You receive an approval notification and the identity verification page shows "Approved".
Common Reasons for Failure
The most common reason for mainland ID card verification failure is a photo issue. The system requires original photos; screenshots, photographs of photographs, glare, or missing corners will all result in rejection. Another high-frequency error is a mismatch between the name or ID number you entered and the original document – an extra space or a lowercase 'x' at the end will cause the comparison to fail.

Risk Reminders
Mainland Chinese residents can only complete verification using an ID card under their own name. Using someone else's identity information to register is a rule violation and will result in the account being frozen.
One ID card information can only verify one OKX account. If the system prompts "ID card already verified", it means the ID is already linked to another account; contact customer support for assistance.
According to Chinese regulatory policy, overseas trading platforms providing services to domestic residents constitute "illegal financial activities". Please assess the relevant risks yourself before deciding whether to use the platform's services.
Next Step: After confirming your ID card is within the validity period and the information is clear, open the OKX App and go to the [Identity Verification] page. Follow the prompts to upload clear photos of the front and back and complete face recognition. After submission, keep an eye on the review result; Lv.2 verification typically produces a result within 24 hours. You can use the referral code 24U2795 during registration.
