The conclusion is very clear: We strongly do not recommend users under 18 to register an OKX account. Even if the initial registration page does not block your application, OKX has a strict mandatory age requirement. When you reach the identity verification (KYC) step, the system will automatically read the date of birth on your ID document, and you will not pass the verification if you do not meet the age requirement.

First confirm which step you are stuck at
If you have not registered yet: When you fill in your date of birth, if you select an underage birthday, the system may directly prompt "Not eligible" and block you from proceeding to the next step. You do not need to try again at this time, as the system will not approve your application.
If you have already registered but are stuck at document verification: After you upload your ID document, the system will automatically extract the date of birth on it. If you are under 18, the verification result will show "Does not meet requirements", and no manual adjustment can change this result.
Are there any exception regions?
OKX's Terms of Service do not have special exemptions for underage users. This rule is set for regulatory compliance, and the platform will take age as a mandatory hard requirement during KYC review. While the legal adult age may not be 18 in some regions, underage ID documents will almost always be rejected by the system under the platform's current standard operation rules.
Risk Reminder
One more critical note: Do not use other people's identity documents to pass verification. Even if you pass the initial registration stage, you may be required to complete facial video verification when you make a withdrawal or trigger the platform's risk control mechanism later. You will fail the verification at that point, and your account may be marked as abnormal, which is much more troublesome to resolve than a simple KYC failure.
Common Verification Failure Causes
A commonly overlooked issue: Many users randomly fill in an underage birthday during registration, thinking they can modify it later. But in the OKX system flow, age verification is based on the document recognition result, you cannot bypass the rule by manually changing the filled birthday, you can only re-submit a valid ID document that meets the age requirement.

Recommended Next Steps
If you do not meet the minimum age requirement for now, do not repeatedly try to submit ID documents. You can wait until you turn 18, then go to the identity verification page to complete the full process again. If your application has already been rejected due to age issues, you can keep your existing account, and upload your new valid ID document once you meet the requirement, the system will automatically re-evaluate your eligibility.
