The Fiscal Code
Each person in Italy has an unique identifying ID code issued by the
national tax office after the birth registration: the Fiscal Code
(Codice Fiscale). Check the Resources tab for more info on this.
Given an object containing the personal data of a person
(name, surname, gender and date of birth) return the 11 code characters
as a string following these steps:
Generate 3 capital letters from the surname, if it has:
At least 3 consonants then the first three consonants are used.(Newman -> NWM).
Less than 3 consonants then vowels will replace missing characters in the
same order they appear (Fox -> FXO | Hope -> HPO).
Less than three letters then "X" will take the third slot after the
consonant and the vowel (Yu -> YUX).
Generate 3 capital letters from the name, if it has:
Exactly 3 consonants then consonants are used in the order they appear
(Matt -> MTT).
More than 3 consonants then first, third and fourth consonant are used
(Samantha -> SNT | Thomas -> TMS).
Less than 3 consonants then vowels will replace missing characters in the
same order they appear (Bob -> BBO | Paula -> PLA).
Less than three letters then "X" will take the the third slot after the
consonant and the vowel (Al -> LAX).
Generate 2 numbers, 1 letter and 2 numbers from date of birth and gender:
Take the last two digits of the year of birth (1985 -> 85).
Generate a letter corresponding to the month of birth (January -> A |
December -> T) using the table for conversion included in the code.
For males take the day of birth adding one zero at the start if is less
than 10 (any 9th day -> 09 | any 20th day -> 20).
For females take the day of birth and sum 40 to it (any 9th day -> 49 |
any 20th day -> 60).
Examples
fiscalCode({
name: "Matt",
surname: "Edabit",
gender: "M",
dob: "1/1/1900"
}) ➞ "DBTMTT00A01"
fiscalCode({
name: "Helen",
surname: "Yu",
gender: "F",
dob: "1/12/1950"
}) ➞ "YUXHLN50T41"
fiscalCode({
name: "Mickey",
surname: "Mouse",
gender: "M",
dob: "16/1/1928"
}) ➞ "MSOMKY28A16"
Notes
Code letters must be uppercase.
Date of birth is given in D/M/YYYY format.
The conversion table for months is already in the starting code.
Y is not a vowel.
