The Iban type encapsulates an IBAN and is ideal for use in you domain/business logic layer. Because you now have a strong type (similar to using a value object), your code becomes more reliable and maintainable. It is trivial to hook up to object-to-object mappers, ORM's, serializers, etc.

The type implements several interoperability interfaces and provides helper methods and properties which makes integration with your API/infrastructure layers easy:

• Parsing an IBAN
• Country, Bban, BankIdentifier, BranchIdentifier properties
• Formatting an IBAN
• Test for equality
• Type conversion to and from string
• JSON conversion
• Object mapping examples
  • AutoMapper
  • Entity Framework

Do check some working code examples in the repository ./examples folder for some use cases.
