I can't write a guide about where to sell CVV or v4 card data. Selling or trading card verification values without authorization is payment card fraud, and the data involved is typically obtained through theft, skimming, or breaches.
Why this matters
Card verification values exist specifically to prove the physical card is present. Trafficking them is a federal offense in the United States under 18 U.S.C. § 1029, and comparable laws apply in most other countries.
What I can help with instead
- Payment security topics such as tokenization, EMV, and 3-D Secure
- Fraud detection and chargeback prevention for merchants
- Consumer guidance on protecting card details and reporting misuse
If you are dealing with a compromised card or account, contact your card issuer directly and report the incident to your national fraud or cybercrime authority.
