About Us

Welcome to Namso Gen!
At Namso Gen, we’re dedicated to streamlining your development and QA workflows with a simple yet powerful tool—our Test Credit Card Number Generator. Whether you’re building payment systems, validating UX flows, or stress-testing e-commerce solutions, our generator is designed to support your work safely and effectively.

Our Mission

We aim to eliminate risk and friction in the testing process. Real credit card data poses privacy hazards and compliance challenges like PCI DSS. That’s why we deliver realistic—but entirely fictional—credit card numbers, complete with CVV codes and expiration dates that pass industry-standard checks but never connect to actual bank accounts. Our numbers pass the Luhn Algorithm (MOD 10) validation while remaining completely inert and unusable for real transactions.

Why Developers & Testers Choose Us

  • Real-World Validation Without the Risk
    Simulate real card behavior without exposing sensitive data. Test your workflows confidently, knowing every card number is safe for non-production use.
  • Flexible Inputs & Automations
    Choose your card type—Visa, Mastercard, American Express, or Discover—or even use a custom BIN. Generate hundreds or thousands of cards in formats like CSV, JSON, XML, SQL, or plain text. Perfect for automated test suites and pre-production environments.
  • Designed for Compliance & Security
    Generate only what you need. Our cards help you stress test fraud detection, payment validation, and input handling—without ever using real customer data.
  • Simple, Effective, Safe
    No sign-ups, no saved data. Our tool is focused, secure, and fast—built with developers, testers, and QA professionals in mind.

How It Works

  1. Select Card Type
    Pick among Visa, Mastercard, American Express, or Discover—each with addressable formats and validation rules.
  2. Customize (Optional)
    Use a specific BIN to test issuer edge cases, or let us pick a valid one for you.
  3. Choose Quantity & Format
    Generate a single card or batches in CSV, JSON, XML, SQL, or simple list formats—tailored to your workflow.
  4. Generate & Use
    Instantly get valid-format card numbers, CVVs, and expiry dates (MM/YYYY). The final digit always conforms to the Luhn check for structural accuracy.
  5. Legal & Ethical Use Only
    These cards are purely for testing. Attempts to use them for purchases will fail, and misuse for fraud is illegal and impossible, as they hold no real value.

Who We Serve

  • Web & Mobile Developers building checkout flows, payment gateways, or subscription systems
  • QAs & Test Engineers validating data input, error handling, and format recognition
  • DevOps & Automation Architects integrating continuous testing into CI/CD pipelines
  • Compliance Teams simulating scenarios without compromising real data
  • UX/UI Designers testing form validation and feedback logic in realistic environments

Commitment to Privacy & Security

Your peace of mind matters. We don’t collect or store any sensitive or personal information—ever. Our generated numbers are completely fictional, with no connection to real credit card accounts. Use them freely, ethically, and with confidence.
