card test data v4 is a curated set of sandbox card numbers, expiry dates, and mapped issuer response codes used to validate checkout, subscription, and refund flows before a release goes live. It is built for developers, QA analysts, and payment operations teams who need predictable, repeatable test outcomes without ever touching real cardholder data. Every entry is synthetic and tied to a specific response so you can reproduce approvals, soft declines, hard declines, and 3-D Secure challenges on demand.

Key Features

• Luhn-valid test numbers covering Visa, Mastercard, American Express, and Discover ranges
• Pre-mapped response codes for approvals, insufficient funds, expired cards, and do-not-honor declines
• 3-D Secure challenge and frictionless test profiles for authentication flow testing
• Expiry date and CVV placeholders formatted for standard hosted payment fields
• Delivered as structured CSV and JSON for direct import into test suites
• Versioned entries so existing automation keeps working across releases
• Includes recurring billing and partial capture scenarios for subscription testing

Materials and Specifications

The dataset ships as plain-text CSV and JSON files with a consistent schema: card number, network, expiry, security code placeholder, expected response, and a short scenario note. Numbers are generated to pass Luhn validation so client-side form checks behave exactly as they would with a live card, and each entry is sandbox-only by design. Version v4 refreshes network ranges, adds new decline scenarios, and documents the expected gateway response for each row so test assertions can be written against a known outcome.

Which payment processors support these test numbers?

Most major gateways, including Stripe, PayPal, and Adyen, accept standard sandbox card ranges in their test modes. Confirm the exact range against your provider's test documentation before writing assertions.

How often is the dataset updated?

Version v4 is refreshed when card networks revise test ranges or add new decline codes, typically a few times per year, and updates are included for existing buyers.
