The calcolo codice fiscale is quick when you type your name data into an official algorithm that returns a codice fiscale with 16 alphanumeric characters. The service is free, and it follows the algorithm tied to D.M. 23/12/1976. If you want calcola codice fiscal without guessing parts, use that official flow and double-check each input. Questo codice fiscale stays the same structure everywhere in Italy.

Come si calcola il codice fiscale?

The calcolo codice fiscale follows six key steps, and each step fills a specific part. The tool calcola codice fiscal by taking consonants from surname and name, then using birth year, month letter, day and sex rules, and finally a control letter. Everything matches what the source describes, including the “X” padding when consonants are not enough. You end up with a 16-character codice fiscale.

1. First, take the first three consonants of each surname, then fill missing letters with the needed vowels. If the surname still has fewer than three characters, add “X” until it reaches three characters for the surname part.
2. Next, take the first three consonants of the name, using the same consonant, vowel, and “X” exceptions as the surname. This gives you three characters for the name part.
3. Now, use the last two digits of the birth year, because for births before 2000 you take only the final two digits. This step keeps the year portion short and consistent.
4. Then, convert the birth month into a letter using a predefined table mapping letters to numbers like A=01, B=02, C=03, and so on. This step produces one month letter.
5. After that, write the day of birth, and add 40 to the number if the person is female, as the source spells out. This creates the day-and-sex code.
6. Finally, compute the control letter using the other 15 characters you already built. The source says the full process generates unique codice fiscal for each person.

1. Prima parte: cognome

The first part uses the first three consonants of the cognome you enter. If the cognome has fewer than three consonants, the algorithm adds the missing vowels, and if there are still too few characters, it pads with “X” until you reach three characters. This step matters because it locks the surname segment that starts the codice fiscal. It keeps the output consistent with the official structure described in the source.

2. 2. Parte: nome

For the second part, you take the first three consonants of the nome. You still apply the same rules from the cognome, meaning you add missing vowels if there are not enough consonants, and you use “X” if you still can’t reach three characters. This mini-rule set keeps the calcolo codice fiscal predictable. After this step, your codice fiscal already has both name and surname parts in place.

3. 3. Parte: anno di nascita

Si usano le ultime due cifre dell'anno di nascita. For a person born before 2000, the algorithm takes only the final two digits of the year, instead of the full four-digit value. That way, the birth year part stays short and standardized inside the 16-character codice fiscale. So basically, you always end up with two year digits feeding the later steps.

4. 4. Parte: mese di nascita

Il mese è rappresentato da una lettera secondo una tabella predefinita. The source even gives the example mapping style A=01, B=02, C=03, and so on, so you know the month becomes a letter code rather than a number. Here is the format the mapping follows, letter to numeric code style:

| Mese | Lettera |
|---|---|
| Gennaio | A=01 |
| Febbraio | B=02 |
| Marzo | C=03 |
| Aprile | D=04 |
| Maggio | E=05 |
| Giugno | F=06 |
| Luglio | G=07 |
| Agosto | H=08 |
| Settembre | I=09 |
| Ottobre | L=10 |
| Novembre | M=11 |
| Dicembre | N=12 |

5. 5. Parte: giorno e sesso

Il giorno di nascita è scritto così: per i maschi il numero resta, per le femmine si aggiungono 40. So for the calcolo codice fiscal, you start with the day number, then you add 40 to that day number when the person is female, exactly like the source states. This keeps the day part tied to gender rules inside the codice fiscal. Honestly, this is one of the easiest steps to mess up if you skim.

6. 6. Parte: lettera di controllo

The last piece is a “lettera di controllo” calculated using the first 15 characters. The source says the calcola codice fiscal uses the official coding rules tied to D.M. 23/12/1976, so the control letter is not random. This step helps detect inconsistencies because it depends on what you already built. When you finish this final letter, you’ve got the full codice fiscale structure.
