The short answer

A "fullz" bundle is a set of stolen payment and identity records. Buying, selling, or using one is a federal crime in the United States under 18 U.S.C. § 1029 and 18 U.S.C. § 1028. No guide makes that transaction legal or safe, so this page covers what actually matters: why the offers fail, how issuers block card-not-present fraud, and what to do if your own card data is exposed.

What a fullz bundle claims to contain

  • Card number, expiration date, and CVV or CVC
  • Cardholder name, billing address, phone, and email
  • Sometimes a Social Security number, date of birth, or account logins

Each item is a separate piece of stolen personal data. Held together, the set raises the harm to the victim and the penalty for the holder.

Why the buying side loses

  1. There is no escrow. Sellers on carding forums take crypto and deliver nothing, or deliver data that was already burned.
  2. "Checkers" and "validators" are often the same people selling the data. The tool that confirms a card is live is also the tool that reports the card to the issuer as compromised.
  3. Issuers decline the charge before any seller guarantee expires. CVV verification, address verification, 3-D Secure challenges, and velocity rules stop most card-not-present attempts on first use.
  4. The buyer's own setup is the evidence. Device fingerprinting, IP reputation, and merchant fraud scoring tie an attempt to a person, not just to a card number.
  5. Chargebacks land on the merchant, and investigators follow the money. Card networks and processors log every attempt.

How the CVV field protects real buyers

The CVV is a three or four digit code printed on the card that proves the person typing the card number also holds the physical card. PCI DSS Requirement 3.2 forbids storing that code after authorization, even in encrypted form. That single rule is why a leaked table of card numbers is far less useful to a criminal than a leaked table with CVVs attached.

If your own card data is exposed

  1. Freeze the card in your banking app or call the number on the back.
  2. Request a new card number, not just a new expiration date.
  3. Change the password on the account and turn on two-factor authentication.
  4. Pull your credit reports and dispute any account you do not recognize.
  5. File a report at IdentityTheft.gov, and report card-not-present fraud to the IC3.

For merchants

  • Never store the CVV. If you find it in a database, logs, or a support ticket, treat that as a breach.
  • Replace stored card numbers with network tokens.
  • Require 3-D Secure on high-risk orders and on new customers.
  • Keep full card numbers out of application logs and error tracking.
  • Review address verification results before you ship physical goods.
