Key Preparations for Dual Nationality Users Registering on OKX
For dual nationality users registering on OKX, the most critical preparation is: from the very beginning, select one "Country/Region of Residence" and then ensure that all subsequent KYC documents, IP addresses, and proof of address point to that same country.
OKX adheres to global compliance requirements and provides corresponding service permissions based on the user's country of residence. If information crosses between different countries, it can easily be flagged as a high-risk account by the risk control system, leading to restricted account functions, requests for additional materials, or even freezing of withdrawals.
Prerequisite: Clarify the Relationship Between "Residence" and "Nationality"
OKX's key reference is the user's "Country/Region of Residence", not the nationality on the passport. If you live in Country A long-term but hold a passport from Country B, you should use your actual place of residence as the basis for registration. The chosen residence directly affects fiat deposits and withdrawals, available product types, and counterparties.
Step 1: Choose a Registration Country and Maintain Consistency
What to do: Choose the country/region where you actually reside and can provide valid supporting documents when registering.
How to do it:
Avoid IP conflicts: When logging in, try to use an IP address consistent with that country. Frequently switching VPNs or logging in from different countries may trigger risk control inquiries.
KYC information must match exactly: The name and address you provide must be completely consistent with the identity document (passport or driver's license) and proof of address you subsequently submit.
When is it done: You have chosen a "single identity" for registration and verification, and that identity has corresponding valid documents and proof of address.
Step 2: Prepare Compliant KYC Materials (The Most Critical Part)
What to do: Prepare a complete set of identity verification materials that meet the requirements of the registered country.
How to do it:
Proof of Identity:
Choose the most convenient valid document you have (passport or driver's license). The document must be within its validity period, with a clear, unobstructed photo.
Scenario A / Scenario B: If you have chosen Country A as your residence, use your valid document from Country A. If you do not have a Country A document, you can use your Country B passport, but it must be accompanied by proof of address in Country A and a visa/residence permit.
Proof of Address:
This is the most common stumbling block. OKX requires a proof of address document issued within the last 3 months, clearly showing your name and full residential address.
Acceptable document types include: utility bills, bank statements, government correspondence.
Note: Documents must be original PDFs or clear photographs; screenshots are generally not accepted. P.O. Box addresses are not accepted.
When is it done: You have on hand a valid identity document and a proof of address from the last 3 months, and the address information on both matches.
Step 3: Understand Account Risks and Risk Control Inquiries
What to do: Understand the risk control reviews you may face as a dual identity holder.
How to do it:
OKX's risk control system primarily flags "potentially high-risk accounts" for actions such as unclear source of funds, abnormal device logins, and connections to sanctioned regions.
If the system detects that you have used the Tor browser, frequently changed IP addresses, or your name matches a name on a sanctions list, it may trigger an inquiry about your employment/residence information.
If inquired, providing truthful information is key. If you are a freelancer, you need to explain your source of income (such as DeFi mining, airdrops) and provide wallet screenshots or signatures as supporting evidence.
When is it done: You understand the risk control logic your account might face and are mentally prepared to provide genuine materials when required.
Risk Reminders
Do not use false information: Registering with a fake country or address may result in permanent account freezing and inability to withdraw assets.
Country information generally cannot be changed: Once KYC is completed, the country/region information cannot be modified on your own in principle. If a change is needed, you must submit complex documents such as immigration proof to customer service.
Key principle: Compliant users only need to cooperate by providing genuine materials; the security of assets and accounts is usually not affected.
How to Confirm You Are Ready
Before starting the registration, check whether these four pieces of information all point to the same country:
The country selected at registration
The address on your identity document (or the issuing country)
The address on your proof of address
The IP address of your login device
If all four point to the same person and the same country, and the information you fill in remains logically consistent, then your registration preparation is compliant and sufficient.
