django-localflavor is a collection of assorted pieces of code that are useful for particular countries or cultures. These are called the "local flavor" add-ons and live in the localflavor package. Inside that package, country- or culture-specific code is organized into subpackages, named using ISO 3166 country codes. Most of the localflavor add-ons are localized form components deriving from the forms framework - for example, a USStateField that knows how to validate U.S. state abbreviations, and a FISocialSecurityNumber that knows how to validate Finnish social security numbers.
