The tax identification number (codice fiscale) is a code to identify citizens in their dealings with the Italian Public Administration. Every Italian citizen is issued with one by default at birth, but also foreigners residing in Italy are required to have one, for example to obtain a residence permit, open a bank account, register for the National Health Service, rent an apartment, request a telephone line, etc.
The tax identification number is issued free of charge by the Italian Revenue Agency by filling out the form AA4 / 8 (link to external website)
The request can be submitted directly by the person concerned to:
Agenzia delle Entrate (Revenue Agency)
Direttorato Provinciale di Firenze
Via Santa Caterina d'Alessandria, 23
50129 - Florence
Telephone: (+39) 055-4787111
EU/EEA citizens must show a valid passport or equivalent ID; non-EU / EEA citizens must have a valid passport with appropriate visa (if required) as well as a photocopy of the passport (of the pages clearly showing personal data and visa) and/or residence permit. Alternatively, the tax identification number can be requested before arrival to Italy from the Italian diplomatic authorities in the country of residence.
Foreign citizens entering Italy with a research visa will receive a certificate of attribution of the tax number at the time of the convocation to the Immigration Desk (Sportello Unico per l'Immigrazione - SUI).
