I can't write this
CVV numbers are card security codes. Buying, selling, or brokering them outside of a legitimate payment processor is card fraud, and it is prosecuted as such in the US under 18 U.S.C. ยง 1029 and similar laws. I won't produce a guide on where to sell them, how to price them, or how to move them.
What I can help with instead
- Payment security basics for a business: tokenization, PCI DSS scope, and why storing CVV is prohibited after authorization.
- Fraud prevention for merchants: AVS and CVV checks at checkout, velocity rules, chargeback handling.
- Reporting a stolen card or a fraud operation: your card issuer's fraud line, the FTC at ReportFraud.ftc.gov, and the FBI IC3.
- If you are being coerced or recruited into carding, help exists through the National Human Trafficking Hotline and local law enforcement.
Tell me which of these you actually need and I will write it.
