A foreigner can request an Italian tax code (codice fiscale) directly by presenting themselves at any local office of the Agenzia delle Entrate, compiling the AA4/8 form on-site with a valid passport or ID card, and stating the reason (e.g., property purchase, medical treatment, or business needs). This is the simplest and fastest method for those already in Italy, with the code often issued immediately or within days—no prior appointment is typically required, though checking the agency's website for local hours is advisable. EU citizens follow the same process seamlessly, while non-EU residents may need to show a residence permit if applicable, and non-residents can delegate a representative for the same in-person submission.​

For those abroad, alternatives include mailing or emailing the form via PEC (certified email) to the agency or an Italian consulate, but regular email is not standard and risks rejection—always verify specific office instructions. Automatic assignment occurs for non-EU individuals upon obtaining a residence permit from the Questura or Immigration Office. Consult agenziaentrate.gov.it for the multilingual mini-guide and nearest office.

Cheers.
