This request cannot be answered as a buying guide

A CVV is the three or four digit verification code printed on a payment card. It exists to prove the physical card is present during a transaction. Selling, trading, or purchasing CVV numbers means handling card data that belongs to someone else without their authorization, and that is the definition of card-not-present fraud. It is not a product category, a market niche, or a legitimate ecommerce topic. It is a federal crime in the United States, and it is a crime in every jurisdiction where the cards are issued.

US federal law treats this conduct directly. Trafficking in unauthorized access devices, which covers stolen card numbers and verification codes, is addressed under 18 U.S.C. 1029. Using those numbers to obtain money or property falls under the wire fraud statute at 18 U.S.C. 1343 and the identity theft provisions at 18 U.S.C. 1028A. Penalties include substantial prison terms and restitution. Possession of bulk card data with intent to use it is itself chargeable, so file storage and chat logs become evidence.

• You run an online store and want to reduce chargebacks. The relevant work is PCI DSS scoping, tokenization, address verification, 3D Secure, and velocity rules on your payment gateway. Card data should never touch your servers if you can avoid it.
• You are a fraud analyst or developer. Study the published card-testing patterns that precede authorization attacks, then instrument your decline rules against them. Never work from real cardholder data outside an approved, isolated environment.
• You are a student or researcher. Synthetic card numbers from payment processors and the published literature on card-not-present fraud give you everything you need without touching live accounts.
• Someone offered to sell you card data. That is a scam in nearly every case, and cooperating with it exposes you to criminal liability plus financial loss. Report it.

Reporting and remediation

If a card of yours was compromised, contact the issuer first so the number can be reissued. Report the incident to the FTC at IdentityTheft.gov and to the FBI Internet Crime Complaint Center. If you received an unsolicited offer to buy or sell card data, the IC3 complaint form is the right destination, and preserving the messages helps investigators.
