CVV guessing means submitting card verification values until one matches. The CVV is the 3-digit code on the back of Visa, Mastercard, and Discover cards, or the 4-digit code on the front of American Express cards. A 3-digit code has 1,000 possible values. A 4-digit code has 10,000. Guessing is not a shortcut. Issuers count failed attempts, payment networks score the traffic, and the conduct is a federal crime under 18 U.S.C. § 1029.
The card verification value exists to prove the physical card is in hand. Visa calls its version CVV2. Mastercard calls it CVC2. American Express calls it CID. Merchants that accept card-not-present orders, such as online stores and phone orders, send the value inside the authorization request. The issuer compares it against its record and returns one of three responses: match, no match, or not processed.
In the US, 18 U.S.C. § 1029 covers fraud and related activity in connection with access devices. A card number with its CVV counts as an access device. Statutory maximums reach 10 years for most first offenses and 20 years for certain aggravated counts, plus fines and restitution. State laws add separate charges. The FTC and the FBI both treat bulk card testing as organized fraud.
CVV guessing differs from skimming, which copies card data at a terminal, and from phishing, which asks a cardholder to type the code. Those methods obtain real values from a real card. Guessing does not, and the failure rate compounds with each attempt.
