Important notes

• Regional restrictions – The platform does not serve users in certain U.S. jurisdictions, Iran, North Korea, and a few other locations.
• Scam awareness – While the platform itself employs robust security, users should stay vigilant against phishing or impersonation scams that claim to be “official” investment offers.

8. Frequently Asked Questions

1. I’m not receiving SMS or email verification codes

• Possible reasons: network latency, carrier filtering, incorrect entry, expired code, risk‑control limits.
• Solutions:

1. Wait 3‑5 minutes and retry; check any spam or carrier “blocked” folders.
2. Switch networks (Wi‑Fi ↔ cellular) and restart the app.
3. Verify that the phone number and email are entered correctly, then request a new code.
4. If you encounter repeated blocks, try a different device or wait 24 hours before trying again; contact support if needed.

Tip: Use a phone number that is registered to you under your real name to avoid KYC complications later.

2. The registration page says “Account already exists”

• Reason: The mobile number or email you entered is already linked to an existing OKX account.
• What to do: Attempt to log in and use the “Forgot Password” flow; if the account is not yours, contact support with identity proof to request closure and then re‑register.

3. My invitation code / discount didn’t apply

• Reason: The code was omitted during sign‑up or the link was invalid.
• Fix: Ensure you used the dedicated invitation link or entered `B2345`. After logging in, go to Profile → Promotions → Invite & Referral → My Fee Discount to confirm the 20 % reduction. If it still does not appear, reach out to support; the discount is only available to brand‑new users.

4. Uploading my ID card fails

• Common causes: blurry photo, occlusions, expired document, mismatched information, or automatic recognition errors.
• Recommendations:

1. Photograph the ID on a well‑lit white background, making sure all four corners are visible.
2. Upload the original image without compression.
3. If the system still rejects it, try manually typing the ID number or capture the photo on a different device; you can also request manual review via support.

5. Facial recognition fails

• How to resolve:
• Remove hats, masks, glasses and keep a clean‑shaven face.
• Choose a uniformly lit area with a plain background.
• Follow the prompts for nodding, shaking head, opening mouth, etc.
• Avoid peak verification times (09:00‑11:00 and 15:00‑17:00); if it still fails, request an audio‑video KYC with support.

6. How long does KYC take?

• Basic verification – Instant (usually within 5 minutes).
• Advanced verification – 1‑3 business days, requires additional documentation.
• If denied –
