DevLeap, an Italian technology consultation group, provides a web service for matching an Italian citizen with their Codice Fiscale. A Codice Fiscale is a tax identification number used in all interactions with government agencies and public administration in Italy. It is a unique identity code similar to the National Insurance number (NI) in the UK or the Social Security Number (SSN) in the US.
The DevLeap Codice Fiscale API provides users with a programmatic method for retrieving a citizen's information from their Codice Fiscale and vice versa. This API uses SOAP calls issued in XML format.
The DevLeap website is offered in both English and Italian.
