Should Indonesian Users Register on OKX with Phone Number or Email?
For Indonesian users, this is not an either‑or choice – OKX registration requires both a phone number and an email address. Both must be bound to the account; neither can be skipped. However, the registration process can be started using either a phone number or an email as the entry point. What you really need to decide is which one to use as your initial registration entry, and which one will be more important in your day‑to‑day usage later.

Below is the step‑by‑step process for Indonesian users and a comparison of the two entry points.
Step 1: Choose your registration entry point – phone number or email
Open the OKX app or website and tap [Sign Up]. In the "Country/Region" selection, find and choose "Indonesia". The system will automatically show the Indonesian country code +62.
Now you need to pick your entry point:
Option A: Use phone number as the entry point → Enter your Indonesian mobile number (e.g., 0812xxxxxxx; the +62 code is already filled in), tap to get a verification code, and enter the 6‑digit code you receive via SMS.
Option B: Use email as the entry point → Enter your email address (we recommend an international email such as Gmail or Outlook), tap to get a verification code, and enter the 6‑digit code sent to your inbox.
Completion criteria: The verification code is validated and the page moves to the next step.
Prerequisites: The phone number must be able to receive international SMS, and the email address must be able to receive messages. Major Indonesian operators (Telkomsel, XL Axiata, Indosat) normally have no issues receiving OKX verification SMS.
Step 2: Add the other contact method (mandatory)
After verifying your chosen entry point, the system will force you to bind the other contact method.
If you started with a phone number: The system will next ask you to enter an email address and verify the email code. If you started with an email: The system will next ask you to enter a phone number and verify the SMS code.
In other words, no matter which method you use to begin, your account will end up with both a phone number and an email bound to it. This is a mandatory requirement for OKX, not an optional step.
Completion criteria: Both the phone number and email are verified successfully.
Common failure reason: The phone number has already been registered. Each phone number and email can only be linked to one OKX account. If the system says "This phone number is already registered", it means you already have an account. You can try logging in with that number, or contact customer support.
Step 3: Set your password and complete registration
Create a login password. Requirements:
8‑20 characters long
Contains uppercase letters, lowercase letters, and numbers
Special characters are recommended
Read and agree to the Terms of Service, then click confirm to finish registration. The system will show a success prompt and guide you to the identity verification (KYC) page.
Completion criteria: The system confirms successful registration and you are logged into the account.
How your entry point choice affects daily use: a guide for Indonesian users
Although both the phone number and email must be bound during registration, the "primary entry point" you choose will influence your daily convenience. Here are the key differences:
| Comparison | Phone number entry (+62 Indonesia) | Email entry |
|---|---|---|
| Login method | Phone number + password, or SMS code login | Email + password |
| Password recovery | Reset via SMS verification code | Reset via email link |
| Receiving important notifications | Some system notifications go to email | All notifications default to email |
| Practicality in Indonesia | Quick login; no need to remember an email | Better for multiple devices; email rarely changes |
| Risk when traveling abroad or changing numbers | If you change your number, you must update it or you won't receive verification codes | Not affected by phone number changes |
Recommendations:
If you live in Indonesia and plan to use the same mobile number long‑term, choose phone number as your entry point – logging in with a phone number is generally faster than typing an email.
If you frequently travel across borders, or worry you might change your phone number later, choose email as your entry point – email tends to be more stable than a phone number, and all system notifications will be sent to your inbox by default, so you won't miss anything.
Completion criteria: You have selected your entry point and completed registration.
Risk reminders:
Both the phone number and email must belong to you personally, otherwise you will not pass identity verification. One identity document can only be linked to one OKX account, and once KYC is completed this cannot be changed.
OKX is subject to local regulatory requirements in emerging markets like Indonesia. The country you select during registration must match the nationality used for KYC. If you choose "Indonesia" as your region, you must use an Indonesian ID card or other valid identity document for identity verification.

How to confirm everything is working
After submitting the registration, try logging in with the entry point you chose. If you can access your account successfully, registration was completed.
Next step: Once the account is created, you must complete identity verification (KYC) before you can deposit, trade, or withdraw funds. Unverified accounts have limited functionality. Go to [Profile] – [Identity Verification] and follow the instructions to submit your Indonesian ID or passport. Verification is usually completed within 1–10 minutes.
