Should Korean Users Choose Phone Number or Email to Sign Up for OKX?
The conclusion is clear: Both are required, but Korean users should prioritize ensuring their phone number (with the +82 country code) is usable, while also binding an email address.

This is not a choice—it's a mandatory requirement from OKX: you must bind both a phone number and an email during registration. Neither can be omitted.
Precondition: Understanding the Special Environment for Korean Users
Before discussing "which to choose," it's more important to confirm: OKX's current availability in South Korea.
According to public information:
The local OKX Korea site (OKEX Korea) has been marked as "ceased operations." Do not attempt to register on the discontinued local site.
The international site OKX has not completed registration with Korea's Financial Intelligence Unit (FIU). Starting January 28, 2026, unregistered overseas crypto apps cannot be listed or updated on Google Play in South Korea. Android users will be unable to download or update the OKX app through the official app store.
This means Korean users currently primarily access the OKX international site via the web interface, rather than downloading the app from Google Play.
Step 1: Prepare Registration Materials
What to do: Before starting registration, make sure you have the following information ready.
How to do it:
| Required Information | Specific Requirements |
|---|---|
| Korean Phone Number | A Korean number registered under your name that can receive international SMS verification codes (area code +82) |
| Frequently Used Email | An email address that can receive messages normally (QQ Mail, 163 Mail, Outlook, etc. are all acceptable) |
| Identity Document | Passport recommended (typically yields a higher KYC success rate) |
How to know you're done: Both your phone number and email can successfully receive verification messages.
Step 2: Choose the Correct Registration Path
What to do: Complete registration using the correct region settings.
How to do it:
Visit the OKX official website www.okx.com and click [Sign Up]
In the "Country/Region" dropdown, select [South Korea]
The phone area code will automatically match +82 (South Korea)
Follow the on-screen instructions to enter your email and phone number, receive and input verification codes, and set a password
How to know you're done: The page shows that registration was successful, and you have been logged into the account homepage.
⚠️ If the page prompts "Region not supported" or cannot be accessed, it may be an IP address issue. Korean users using a local network to access the OKX web version are currently still able to do so.
Step 3: Understand the Roles of Phone Number and Email
What to do: Clarify the uses of both so you don't mix them up later.
How to do it:
| Comparison | Phone Number (+82) | |
|---|---|---|
| Primary Use | Receive SMS verification codes (for login, trading, withdrawals, etc.) | Receive system notifications, verify identity, and a crucial credential for password recovery |
| Usage Scenarios | Real-time verification for daily logins and sensitive operations | Registration, KYC notifications, important announcements, and a backup channel for forgotten passwords |
| Can Be Omitted? | No, must be bound during registration | No, must be bound during registration |
How to know you're done: You understand that the two serve different purposes: use the phone number for daily verification codes, and keep the email as a backup channel for important notifications and account recovery.
Common Reasons for Failure
Not completing KYC after registration: Accounts without identity verification cannot perform core operations such as trading, depositing, or withdrawing.
Phone number cannot receive international SMS: Some Korean numbers may be restricted by the carrier from receiving international verification codes. Contact your carrier to confirm.
Bound only email but not phone number: The registration process requires both to be bound simultaneously; one alone is insufficient.
The local OKX Korea site has ceased operations: Use the international site www.okx.com for registration. Do not attempt to use the discontinued Korean local site.
Risk Reminder
According to Korean regulations, overseas exchanges not registered with Korea's FIU cannot offer app downloads via Google Play. Korean users currently use OKX primarily through the web version.
The phone number used for registration must be under your own name; otherwise, subsequent KYC verification will fail.
Once KYC is completed, the country/region information is very difficult to change. Be sure to truthfully select South Korea during registration.

How to Confirm You Have Correctly Completed Setup
Log in to your OKX account, go to [Profile] → [Security Settings], and check:
Phone number is displayed as a Korean number starting with +82
Email shows the email address you bound
Identity verification status shows "Verified"
If all three items are confirmed, your account's basic configuration is complete. If you are currently in Korea, accessing the OKX web version and completing registration with a Korean phone number is the most reliable approach under current circumstances.
