Multiple accounts FAQ
According to the Platform's Terms of Service, OKX operates through multiple legal entities worldwide. Each user may register only one account under the same legal entity. Duplicate registration and identity verification are not supported, and each identity document may be linked to only one account. This applies to all accepted documents, including identity cards and passports.
If you have already verified an OKX account using your identity card or passport but cannot remember the original account or no longer have access to its registered phone number or email address, you may be unable to complete identity verification on a newly registered account. Please refer to the following guidance.

7. The system says "Identity information already exists" when I register a new account, but I cannot remember the phone number or email linked to my old account

This message means your identity may already be associated with another OKX account. Check whether the verification page displays a masked email address or phone number that you recognize.
If you don’t recognize or can’t recall the account details, use the identity-association or account-ownership review option on the verification page.

Don’t repeatedly submit the same identity documents or try to verify additional accounts, as each user can have only one verified primary personal account.
