The short answer
CVV data has no legal market. Selling a card verification value is trafficking in an unauthorized access device under 18 U.S.C. § 1029. A first federal offense carries up to 15 years in prison when the value traded in a one-year period reaches $1,000. Banks, processors, and card networks do not buy these codes. A listing that claims otherwise is fraud aimed at the seller or at the buyer.

What the code is
Visa, Mastercard, and Discover print 3 digits on the back of the card. American Express prints 4 digits on the front. The issuer generates the value at card creation and ties it to the account number and the expiration date. The code is a check against a card number typed with no card present.

PCI DSS Requirement 3.2.2 forbids merchants from storing the value after authorization. A merchant that keeps CVV2 in a database fails an assessment and loses card acceptance.
Why the word “effective” does not apply
The phrase implies a working method and a paying buyer. Both are missing.
- Acquirers close merchant accounts tied to card data sales. Chargeback rates above 1% trigger an audit and termination.
- Issuers void a compromised number within hours of a fraud report. A sold code has a shelf life measured in hours.
- Federal agents run carding stings every year. An undercover buyer is a standard tactic.
Penalties in federal law
18 U.S.C. § 1029(a)(2) covers trafficking in unauthorized access devices. § 1029(a)(3) covers possession of 15 or more devices with intent to defraud. § 1029(c)(1)(A)(i) sets a maximum of 15 years for a first offense under either section. 18 U.S.C. § 1028A adds 2 years, consecutive, when the offense uses another person's identity. Restitution and forfeiture sit on top of the prison term.
How the activity gets caught
Issuers score each authorization on device, location, and purchase history. One card number used in two states within an hour fails that check. Cardholders dispute the charge, the merchant files a chargeback, and the processor traces the traffic back to the account. The FBI Internet Crime Complaint Center logs the reports and groups cases by card range and by merchant.
Legitimate routes for the same goal
- Report a leaked card value to the issuer, using the number on the back of the card.
- File a complaint with the FBI IC3 if a site offered card data for sale.
- For merchants: move card capture to a PCI-validated point-to-point encryption device or a hosted payment page.
- For researchers: work under a written scope with the issuer or a published bug bounty program.
Bottom line
No procedure, tool, or marketplace makes a CVV sale work. The act is a felony with a fixed penalty range, and the data loses value on the day it leaks.
