Answer

International CVV test methods use sandbox card numbers from payment processors. These numbers pass CVV checks in test mode. They do not work for real charges. Buying or selling real CVV data is a crime.

What a CVV Is

A CVV is a 3-digit code on Visa, Mastercard, and Discover cards. American Express uses a 4-digit code. The code sits on the card. Banks call it CVV2, CVC2, CID, or CSC. The code proves the cardholder has the physical card.

Legal Test Methods

International Differences

CVV checks vary by region. In the US, CVV is often optional for card-present transactions. In the EU, PSD2 requires strong customer authentication. That rule adds 3D Secure to most online payments. In Brazil, local processors may require CPF or CNPJ along with CVV. In Japan, JCB uses a 3-digit CVV. Test methods must match the local card network rules. Use the processor's regional sandbox. Do not use a US test card for an EU acquirer without checking support.

PCI DSS Rules

PCI DSS Requirement 3.2 prohibits storing CVV after authorization. The rule applies to all international markets. Test environments must not use real card data. PCI DSS Requirement 6.4 covers secure test data. Use synthetic data or processor-provided test cards. A merchant that stores real CVV faces fines and loss of card acceptance.

How to Run a Test

  1. Open a sandbox account with your payment processor.
  2. Get the test card numbers and CVV values from the processor's docs.
  3. Set the transaction amount to a small value, such as 1 USD or 1 EUR.
  4. Submit the test CVV. Check the response code. A code of 00 means approval. A code of 05 means decline.
  5. Repeat for each card network you support. Test Visa, Mastercard, Amex, and JCB one by one.

Illegal Purchase of CVV

Websites that sell CVV data are fraud markets. US law 18 U.S.C. § 1029 makes it a crime to traffic in access devices. The UK Fraud Act 2006 covers the same conduct. Penalties include prison time and fines. Payment processors block accounts linked to carding. Do not buy CVV data from any source.
