What to Do If You Selected the Wrong International Country Code on OKX?
Selecting the wrong country code during registration is not uncommon. However, once identity verification (KYC) is completed, this information is tied to your account and cannot be changed at will. The remedy depends on whether you have completed KYC: unverified users can change it themselves, while verified users need to contact customer support and submit supporting documents.

Prerequisite: Check Your KYC Status First
Log in to OKX, go to [Profile] → [Identity Verification] page to view your current verification status:
KYC not completed: Country code / country information can still be modified on your own.
KYC completed: Modification rights are restricted, and you need to go through customer support.
If you are not sure which case you are in, go directly to [Security Settings] and check whether there is an "Edit" button next to the "Country/Region" field – if there is, you are unverified; if not, you are verified.
Step 1 (Unverified Users): Modify Directly in Settings
What to do: During registration or in account settings, change the country code/country back to the correct option.
How to do it:
Log in to the OKX App or website, go to [Profile] → [Account Settings] or [Security Settings].
Find the "Country/Region" or "Country Code" field, and click the edit button next to it (pencil icon or "Modify" link).
Select the correct country/region from the dropdown list and confirm to save.
If the system asks you to re-complete KYC, submit new identity documents as prompted.
Completion indicator: The Country/Region field shows your correct country of residence, and the mobile phone country code matches.
Step 2 (Verified Users): Contact Support to Request a Change
What to do: If your account has completed KYC, you need to submit a request to official customer support and provide supporting documents.
How to do it:
Log in to your OKX account, go to [Help Center] or [Customer Support] page.
Explain the situation: you selected the wrong country/code during registration and now request a correction.
Follow the support agent's guidance and submit the following materials (usually required):
Valid identity document (passport or national ID card)
Proof of address issued within the last 3 months (utility bill, bank statement or government letter) clearly showing your name and full residential address
If you have other supporting documents (such as visa, residence permit), submit them as well.
Wait for the review; the review time can range from a few hours to several days.
Completion indicator: After customer support approves, the country/region information has been updated to the correct option, and account functions return to normal.
Step 3: Verify Whether the Phone Number Is Updated Synchronously After the Change
What to do: If the country code change involves the bound mobile phone number, confirm whether the phone number needs to be updated synchronously.
How to do it: Check the phone number verification status in OKX [Security Settings]. If the country code has changed but the bound phone number is still the old one, you need to change the phone number separately:
Go to [Security Settings] → [Phone Verification]
Select [Change Phone Number], follow the instructions to complete verification and update
Note: After changing the phone number, withdrawals will be disabled for 24 hours.
Completion indicator: The phone number's country code matches the Country/Region information, and you can receive SMS verification codes normally.
Common Reasons for Failure
The submitted address proof does not match the target country—for example, you want to change the country to Singapore but submit a Chinese bank statement. The supporting document must point to the target country.
Documents are expired—OKX requires proof of address to be issued within the last 3 months; expired documents will be rejected.
Attempting to change to a high-risk or restricted service region—some countries/regions are not within OKX's service scope, and changing to them will be denied.
Frequent change requests—repeatedly applying to modify country information in a short time may trigger risk control, leading to restricted account functions.
Risk Warning
Country/Region information must be truthful. Providing false information or using someone else's identity documents may lead to permanent account freezing and inability to withdraw assets.
After KYC completion, changing the country usually requires submitting supporting documents. Do not assume you can change it at will; OKX has a strict compliance review process for region changes on verified accounts.
Changing country/region may affect available services. Fiat channels, trading products, and features may differ by country; some features may no longer be available after the change.

How to Confirm You Have Completed the Operation Correctly
Open OKX [Profile] → [Security Settings], and check whether "Country/Region" and "Mobile phone country code" display the correct information.
If the information is updated and account functions are normal, the operation is complete. If the information is inaccurate or account functions are restricted, you should contact OKX customer support for further verification.
