How to Fill in Country/Region and International Dialing Code When Registering on OKX for Singapore Users
When Singapore users register on OKX, simply select "Singapore" for Country/Region, and the international dialing code "+65" will be automatically displayed—no need to manually change it. Both must match; do not have a situation where the region is set to Singapore but the area code shows China's +86.
1. Registration Step One: Find the Country/Region Dropdown
Open the OKX App or website registration page, and locate the Country/Region dropdown menu near the mobile phone number input field. The registration page typically has two layouts:
Layout A: Select the Country/Region first, then enter the phone number. Find "Singapore" directly in the dropdown.
Layout B: There is an area code display in front of the phone number input box. Click the area code area (the default may be +86), and find "Singapore +65" in the list.
Completion standard: The country name displayed on the page is "Singapore" and the area code shows "+65".
Prerequisites: You can normally access the OKX official website or App registration page, and Singapore is within OKX's service coverage. OKX requires users to register and complete identity verification based on their "country/region of residence."
Common failure reason: Selecting "China (+86)". Some users habitually default to China, but Singapore registration must select Singapore. Choosing the wrong area code may prevent receiving the verification code and could also affect subsequent KYC verification.
2. Enter Mobile Number and Receive Verification Code
After selecting the correct Country/Region, enter your Singapore mobile number, then tap "Get Verification Code".
The mobile number must be a real number issued by a Singapore operator. Since 2002, Singapore mobile numbers are uniformly 8 digits and usually start with 8 or 9.
Enter only the 8-digit number without the area code—the area code has already been filled when selecting the country.
After tapping "Get Verification Code", wait for the SMS to arrive.
Completion standard: The mobile phone receives a 6-digit verification code sent by OKX.
Prerequisites: The phone can receive SMS normally, and the operator has not blocked OKX's SMS channel.
Common failure reason: Entering the area code +65 along with the phone number causes a format error. Singapore mobile numbers are already 8 digits; do not include 65 when entering.
3. Important Notes When Filling Personal Information and Address
When performing KYC identity verification after registration, you will need to fill in detailed residential address information. The address filling specifications are as follows:
Country/Region: Confirm again by selecting "Singapore"
Province/State: If applicable, "Singapore" (Singapore has no provincial-level divisions; you can directly fill in Singapore)
City: e.g., "Singapore"
Detailed Street Address: Fill in English, including street name, house number, building, unit, room number. For example: 10 Anson Road, #15-01, International Plaza
Postal Code: 6 digits, matching the address
Address information must match the actual residential address and you must be able to provide corresponding supporting documents (such as utility bills, bank statements, tenancy agreements, etc.). After registration, OKX generally does not support arbitrary changes to the Country/Region, so choose carefully the first time.
Completion standard: All required address fields are filled, and the street address is complete down to the house number.
Prerequisites: Have a Singapore residential address and corresponding postal code at hand.
Common failure reason: Incomplete address. An address missing the house number cannot pass KYC review.
4. Complete KYC by Uploading the Corresponding Identification Documents
Follow the system prompts to upload the identification documents required for Singapore registration. Singapore users typically need to submit:
A valid passport or Singapore identity card (NRIC/FIN)
A selfie for facial recognition
For some regions or higher-level access, proof of address may be required (such as utility bills or bank statements dated within the last 3 months)
If you use an identification document issued in Singapore, the name and address on the document must be consistent with the information provided during registration.
Completion standard: File upload is successful, and the page shows "Under Review". KYC review usually completes within 1–3 business days.
Prerequisites: The document is within its validity period and the photo is clear and legible.
Common failure reasons: Blurry or reflective documents, or the name on the document does not match the registered name.
Follow-up tip: Open the OKX registration page, first find the Country/Region dropdown menu and confirm that "Singapore" and "+65" are both selected. Then try receiving a verification code with your Singapore mobile number; if you can receive it, proceed to complete KYC. If not, contact your operator first to check whether overseas SMS channels are blocked, to avoid getting stuck at the registration step.
