Frequently asked questions
What is Visa Portal Classic?
It is the classic-layout sandbox card-format tool that builds sample card numbers by scheme for integration testing. Every value is synthetic.
Are the numbers real or usable for payments?
No. They follow the public card format only — not issued by any bank, carry no funds, and cannot be used for real purchases.
Which card types can I generate?
Visa, Mastercard, American Express, Discover and others — each following that scheme's number format and length.
Do the numbers pass the Luhn check?
Yes. Each generated number is built to pass the Luhn (mod-10) checksum, so it is well-formed for testing.
What's the difference from Visa Portal New?
Classic keeps the older layout; Visa Portal New has the redesigned masked-input interface. Both produce synthetic data.
Should I use real card data?
No. Use synthetic values only — never enter a real card number.
