Why we cannot provide this guide
You asked for a buying guide on how to purchase CVVs without being scammed. We cannot fulfill that request. A CVV is the card verification value printed on a credit or debit card. Buying, selling, or trading CVVs is a core component of carding and payment card fraud. It is illegal under U.S. federal law, including the Computer Fraud and Abuse Act and identity theft statutes. Providing advice on how to buy CVVs would facilitate serious financial crimes and put consumers at risk. Instead of a buying guide, we offer this warning: any marketplace that claims to sell CVVs is either engaged in illegal activity or is itself a scam. There is no legitimate way to buy a CVV. If you have encountered an offer to sell CVVs, report it to the FBI's Internet Crime Complaint Center or the Federal Trade Commission. If you believe your own card data has been compromised, contact your card issuer immediately and monitor your accounts for unauthorized charges. We are willing to discuss fraud prevention, secure payment practices, or how to recognize carding scams, but we will not assist with the purchase of stolen financial data.
