I cannot write this guide. Selling CVV or fullz data means selling stolen payment card credentials. In the United States that falls under 18 U.S.C. § 1029, which covers trafficking in counterfeit access devices and unauthorized access devices. Penalties reach 15 years for a first offense and 30 years for repeat offenses under subsection (c)(1)(A).
Similar statutes exist in the UK (Fraud Act 2006, Computer Misuse Act 1990), the EU (Directive 2013/40/EU), and Canada (Criminal Code s. 342). Card networks also treat merchants that touch this traffic as complicit.
What I can write instead, if useful:
- How card issuers detect card-not-present fraud, at a process level.
- How merchants cut chargeback rates with address verification and 3-D Secure.
- How consumers freeze their credit files at the three U.S. bureaus.
- How to report stolen card data to the FTC, IC3, or the card issuer.
Tell me which and I will write it as a plain factual guide.
