IBAN Generator

International Bank Account Number — mod-97 checksum per ISO 13616.

International Validation Generation

Try the demo NuGet: DocumentNumber.Portugal.BankAccountNumber.Generator

How generation works

The IBAN 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.Portugal.BankAccountNumber.Generator

Generator in C#

Program.cs

using DocumentNumber.Portugal.BankAccountNumber.Generator;

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

Console.WriteLine(sample);

Live example
