Linking a bank card to your digital asset account is a crucial step for seamless fiat-to-crypto transactions. This guide walks you through the complete process of linking a bank card to your OKX account—securely, efficiently, and without errors. Whether you're new to cryptocurrency or expanding your investment tools, this step-by-step tutorial ensures a smooth onboarding experience.
Understanding Platform Requirements
Before initiating the bank card linking process, it’s essential to understand OKX’s verification and compliance policies. The platform adheres to strict regulatory standards across different regions, meaning eligibility may vary depending on your country of residence.
To link a bank card successfully:
- You must complete identity verification (KYC).
- Your account should be in good standing with no pending restrictions.
- Some advanced features may require higher verification tiers.
For example, users in regulated markets like the EU or Southeast Asia may need to submit additional documentation before gaining full access to fiat deposit options. Always check your local regulations and OKX's regional guidelines to avoid failed attempts.

Entering Your Bank Card Details
Accuracy is key when inputting sensitive financial information. A single typo can result in failed verification or even temporary account flags.
Required Information:
- Full name as it appears on the card
- 16-digit card number
- Expiration date (MM/YY)
- CVV code
- Billing address (in some cases)
Additionally:
- Ensure the card supports international transactions, especially if using non-local currency.
- Some banks require pre-authorization for crypto-related payments—contact your bank if unsure.
- Certain cards (like prepaid or virtual debit cards) may not be supported due to anti-fraud policies.
⚠️ Pro Tip: Use a primary bank-issued debit or credit card from major networks (Visa, Mastercard). These have the highest success rate on OKX.
Verification and Confirmation Process
After submitting your details, OKX initiates a security check to confirm ownership of the card.
What to Expect:
- A small test transaction (usually under $1) may be charged temporarily.
- You’ll receive an SMS or email with a verification code.
- In some cases, you may need to upload a photo of your card (with sensitive data redacted).
Once verified:
- The test amount will be refunded automatically.
- Your card will appear under “Payment Methods” in your wallet.
- You can immediately begin purchasing crypto with fiat.
If you don’t receive a code:
- Check spam/junk folders.
- Confirm your phone number and email are up-to-date in your profile.
- Wait 5–10 minutes before requesting a resend.
