VISA Generator

Visa card numbers — 13, 16 or 19 digits starting with 4, Luhn check.

International Validation Generation

Try the demo NuGet: DocumentNumber.PaymentCardNumber.VISA.Generator

How generation works

The VISA generator builds a structurally valid sample using the same rules the validator enforces — check digits included. Use it for test data and fixtures; never for production records.

Install the package

bash

dotnet add package DocumentNumber.PaymentCardNumber.VISA.Generator

Generator in C#

Program.cs

using DocumentNumber.PaymentCardNumber.VISA.Generator;

var generator = new VisaPaymentCardGenerator();
var sample = generator.GenerateDocumentNumber();

Console.WriteLine(sample);
