What to Prepare Before Opening an OKX Account with an Overseas Phone Number
To open an OKX account with an overseas phone number, besides preparing a phone number and email, the most critical thing is to ensure that the phone number is under your own name and can receive international SMS normally. Otherwise, subsequent KYC verification and account recovery will run into trouble.
The registration process for an overseas phone number is essentially the same as for a local number, but there are a few easy-to-overlook details to confirm in advance.
1. Things to Prepare Before Registration
1. An overseas phone number under your own name that can receive international SMS
This is the core prerequisite. During OKX registration, a 6-digit verification code will be sent to this phone number. If you cannot receive it, you cannot proceed. Some carriers in certain countries/regions have international SMS reception disabled by default in their plans; it's advisable to check beforehand.
One phone number can only register one OKX account.
2. An email address that can receive emails normally
You must bind an email address during registration and you need to receive an email verification code. All verification messages and system notifications will be sent to this email. You can use Outlook, QQ Mail, 163 Mail, etc.
3. Proof of identity document for persons aged 18 and above
After registration, identity verification (KYC) is mandatory. Unverified accounts cannot perform trading, deposits, withdrawals, lending, or fund transfers. Prepare valid documents such as a passport or local identity card.
4. Confirm your country of residence is not in a restricted service area
Eligibility is determined by your place of residence, not nationality. If you reside in a region not supported by OKX, you cannot register even with an overseas phone number.
2. Registration Steps
Step 1: Select the corresponding country/region
On the OKX App or web registration page, select your phone number's country from the "Country/Region" drop-down list. The system will automatically match the corresponding international dialing code.
Step 2: Enter the phone number
Enter your phone number in the input field after the dialing code. Note: Do not repeat the country code, and do not include the leading "0" from the national prefix; only enter the main digits of your phone number.
Step 3: Receive and enter the verification code
Tap "Get Verification Code", then enter the 6-digit code received. Each code is valid for 10 minutes.
Step 4: Complete email verification and set a password
Registration requires binding both your phone number and email. Follow the prompts to complete email verification and set a password.
Common Reasons for Failure
Unable to receive SMS verification code
This is the most common issue when registering with an overseas phone number. Possible causes and troubleshooting:
Phone number entered in wrong format (including the country code again or keeping the "0" prefix)
Carrier blocked international SMS
SMS blocking apps or system filtering
Phone left on for too long without a restart affecting signal
If you can't receive the code via the app, you can tap "Didn't receive the code" and choose the voice verification option (the system will call and read out the code) as an alternative method.
Phone number already registered
One phone number can only register one account. If it says it's already registered, check if you registered before, or try logging in via the password recovery function.
Email not receiving verification mail
Check your spam/junk folder, or add OKX's sending domain to your email whitelist.
Risk Reminders
The phone number must be under your own name: If the phone number is not registered in your real name, you cannot pass subsequent identity verification, and your account will have trading functions restricted.
Cost of changing the phone number: If your overseas phone number is discontinued, changing the bound number requires facial recognition verification, and withdrawals are disabled for 24 hours after the change.
Final confirmation step:
Open the OKX registration page, select the country/region corresponding to your phone number, confirm the dialing code is correct, and enter your phone number without the prefix. Click "Get Verification Code" — if you can receive it and complete registration, your phone number was entered correctly. If not, first check the format, then try the voice verification code as a backup option. Complete identity verification immediately after registration, otherwise your account functions will be restricted.
