Question 1

What is the Italian Codice Fiscale?

Accepted Answer

The Codice Fiscale is a 16-character alphanumeric tax code assigned to every Italian resident. It encodes the surname, first name, date of birth, gender, place of birth (municipality code), and a final check character.

Question 2

How is the Codice Fiscale check character calculated?

Accepted Answer

The first 15 characters are converted to numeric values using two lookup tables (one for odd positions, one for even). The values are summed, taken modulo 26, and the result is mapped to a letter from A to Z, which becomes the 16th character.

Question 3

Can two people have the same Codice Fiscale?

Accepted Answer

Rarely, yes — when two people share the same first name, surname, gender, date of birth, and birthplace, they would generate the same Codice Fiscale. The Agenzia delle Entrate then alters one digit to disambiguate (a process called "omocodia").
