How to Fill in Country/Region and International Area Code When Indonesian Users Register on OKX
When Indonesian users register on OKX, select "Indonesia" as the country/region, and the mobile area code will automatically or manually be set to "+62". The country/region and area code must match, and you need to remove the leading "0" from the mobile number to receive the verification code successfully. Below are the detailed steps and filling instructions.

1. How to Select "Country/Region" During Registration
Open the OKX app or website, go to the registration page, and the first step is to fill in or select your country/region.
App: Tap 【Sign Up】, find and select "Indonesia" from the "Country/Region" drop‑down list.
Web: Also on the registration page, choose "Country/Region of residence" as "Indonesia".
Completion standard: The drop‑down box shows "Indonesia", usually followed by the Indonesian flag icon.
This selection affects two things: the default value of the mobile area code, and the basis for judging your place of residence during subsequent identity verification (KYC). Choosing a country/region that matches your actual residence is a prerequisite for passing verification smoothly.
2. How to Fill in the International Area Code "+62"
The international area code for Indonesia is +62.
During OKX registration, there are usually two ways to fill in the mobile number:
Case A: The system automatically fills the area code based on country/region
After selecting "Indonesia" as the country/region, the international area code before the mobile number input box will automatically show "+62". You only need to enter the remaining digits of your mobile number in the following input box.
Case B: You need to manually select the area code
If the system does not auto‑fill, tap the area code selection button before the mobile number, find "Indonesia +62" in the list and select it.
Completion standard: The area code displayed before the mobile number input box is "+62", matching the Indonesian local mobile number you provide.
3. Notes on the Format of Indonesian Mobile Numbers
When dialed domestically, Indonesian mobile numbers usually start with digit 0 (e.g., 08123456789) – this 0 is the domestic long‑distance prefix.
However, in international format (including when registering with OKX), you must remove the leading 0 and only fill in the digits after the 0.
Domestic format example: 08123456789
International format example (when filling in on OKX): 8123456789
If you include the leading 0, the system will recognize it as an invalid number and the verification code cannot be sent.
Prerequisites
Prepare an Indonesian mobile number capable of receiving international SMS (Telkomsel, Indosat, XL Axiata and other carriers are supported).
Ensure the mobile signal is normal and SMS blocking is not activated.
Confirm that your place of residence is not on the list of regions with restricted OKX services. Eligibility is determined by residence, not nationality.
Common Failure Reasons
Mismatch between country/region and area code: If you selected "Indonesia" but the area code belongs to another country, or you chose area code +62 but selected a different country/region, the system will refuse to send the verification code.
The mobile number retains the leading 0: Some users, out of habit, fill in the number as they would dial domestically, adding an extra 0, which results in a wrong format.
The mobile number cannot receive international SMS: Some Indonesian carrier plans may have international SMS reception disabled by default. If you still cannot receive the code after several attempts, contact your carrier to confirm.
Risk Reminders
Identity verification consistency: The country/region filled in during registration must be consistent with your actual place of residence and the identity document you submit later; otherwise, it may affect the KYC approval rate.
Cost of changing the bound mobile number: If the Indonesian mobile number is deactivated, replacing the binding requires facial recognition verification, and withdrawals are disabled for 24 hours after the change.
Dynamic policy changes: Cryptocurrency regulations vary by country and change quickly. It is recommended to stay updated with OKX official announcements and the latest regulatory developments in Indonesia.

FAQ
Q: Does OKX support direct trading with Indonesian Rupiah (IDR)? A: Yes. OKX has partnered with local Indonesian payment companies to launch fiat on/off‑ramp channels, supporting direct trading with Indonesian Rupiah (IDR).
Q: What should I do if I never receive the verification code after entering the mobile number? A: First check if there is an extra leading 0 in the number and whether the area code is +62. If the format is correct but you still don't receive it, try switching between Wi‑Fi and mobile data, or wait a few minutes and tap "Resend".
Final confirmation step:
Open the OKX registration page, select the country/region as "Indonesia", confirm the area code before the mobile number is "+62", then enter the Indonesian mobile number without the leading 0 (e.g., 8123456789). Tap "Get verification code" – if you can receive a 6‑digit verification code normally and complete verification, the country/region and area code have been filled in correctly.
