OtterFillHow to fill in the Italian AA4/8 (codice fiscale application)
The AA4/8 is the Agenzia delle Entrate’s form to apply for an Italian tax code (codice fiscale), to report a change in your details, or to ask for a codice fiscale card or a replacement health card (Tessera Sanitaria). You fill it in if you need a codice fiscale and no other office assigns it to you, for example as an EU citizen moving to Italy, a non-resident student or worker, or someone abroad who has to sign a contract or accept an inheritance in Italy.

- Issued by

- Italiano
- Where it goes
- Any Agenzia delle Entrate office, by appointment, or by certified email (PEC) to an office; if you live abroad, also the Italian consulate in your country of residence
- What to bring
- The form signed, and a valid identity document, such as a passport (with a visa if you need one), a residence permit or an ID card valid for travel; for an application for someone else, your own ID and a statement of the reason
- Cost
- The form and its instructions are free to download and print; the agency’s pages for this request name no fee
- What you receive
- A certificate of attribution of the codice fiscale, then by post a codice fiscale card (if you are not in the national health service) or a Tessera Sanitaria (if you are)
- How long it lasts
- The codice fiscale does not expire; it is a 16-character code built from your name, sex, date and place of birth
What this form is
The codice fiscale identifies you in every dealing with the Italian public administration, and is asked for in contracts, leases, loans, tax payments and to register with the health service. For people it is 16 letters and digits worked out from your surname, name, date and place of birth and sex. Only a code issued by the Agenzia delle Entrate is valid; a code from an online calculator is not.
Most people never fill in this form, because another office assigns the code: the town hall (Comune) for newborns, the immigration desk (Sportello Unico per l’Immigrazione) or the police (Questura) for non-EU citizens who apply for a residence permit, and consulates for Italians registered abroad. The AA4/8 is for everyone else, and it is also the form to report a change in your details or a death, or to ask for a certificate or a new card.
The form has 1 page to fill in, in block capitals (stampatello), and 4 pages of instructions. It was approved by the agency’s decision of 24 June 2013; the agency’s current PDF (June 2025) starts with a privacy notice, and the form itself is on the second page. Use the editable PDF from the agency’s site, print it and sign it by hand, or sign it digitally if you send it by PEC.
Who has to fill it in
You fill in the AA4/8 if:
- You are an EU citizen and need a codice fiscale to live, study or work in Italy.
- You live legally in Italy but were never given a codice fiscale, or you are a non-resident student, worker or visitor who needs one (for example a student staying less than 90 days).
- You live abroad and need a codice fiscale for something in Italy, such as a contract, a lease or an inheritance; you then apply at the Italian consulate or through someone you authorise in Italy.
- You already have a codice fiscale and need to change your details, get a certificate of it, or replace a lost, stolen, damaged or undelivered card.
You do not need this form if:
- You are a non-EU citizen applying for a residence permit: the Questura or the Sportello Unico per l’Immigrazione assigns the codice fiscale as part of that application.
- You need your first Tessera Sanitaria: that is issued after you register with the local health authority (ASL), not with this form.
- Your Tessera Sanitaria is about to expire: a new one is sent to you automatically.

Common mistakes
- 1
Using a code from an online calculator
A code worked out by a website has no value, even if it looks right. Only the code the Agenzia delle Entrate issues is valid; get it with this form or from the office that assigns it to you.
- 2
Applying when another office assigns it
If you are a non-EU citizen applying for a residence permit, the Questura or the Sportello Unico per l’Immigrazione assigns your code. You do not need to go to the agency for it.
- 3
Writing your birth town instead of the country
If you were born outside Italy, write the country in Quadro B and EE as the province. Your town abroad does not go on this form.
- 4
Names that do not match your ID
Write your names in full, as in your passport or ID card, without titles, and replace letters such as ü with plain letters (MUELLER). A difference can give you a code that does not match your documents.
- 5
Leaving Quadro D blank when you live abroad
Non-residents must fill in every field of Quadro D. Your card is posted to the address the agency has for you, so check it.
- 6
Ticking RICHIESTA TESSERINO when you are in the health service
If you are entitled to the SSN, you get a Tessera Sanitaria automatically; the codice fiscale card is only for people who are not.
- 7
Forgetting to sign
The form is void without the applicant’s signature. If someone hands it in for you, you also sign the Delega, and every field of it must be filled in.
- 8
Asking for a replacement health card that is about to expire
A new Tessera Sanitaria is sent automatically before it expires. Use box 5 only for a card that was stolen, lost, never delivered or damaged.
Questions and answers
How do I get a codice fiscale from outside Italy?
Apply at the Italian consulate in your country of residence with this form, a copy of your ID and the reason you need it. Some consulates take requests only in limited cases, for example when you cannot authorise anyone in Italy, so check its page. You can also authorise someone in Italy to hand in the form at an agency office, or apply yourself once you arrive.
Can I send the AA4/8 by email?
By certified email (PEC), yes: send the signed form and a copy of your ID to an office’s PEC address. If you sign it with a digital signature, you do not need the ID copy. Ordinary email is not one of the ways the agency lists.
I am an EU citizen moving to Italy. How do I get a codice fiscale?
Hand in the AA4/8 at an Agenzia delle Entrate office, with a valid passport or an ID card valid for travel, and say why you need the code. You can also ask the Italian consulate in your country.
What requester code does a student write?
A non-resident student enrolling at an Italian school or university ticks D and writes 01. A student coming for more than 90 days who is not an EU citizen gets the code from the Questura with the residence permit instead.
How long is a codice fiscale valid?
It does not expire. When it is assigned, the office gives you a certificate, which you can use until the card arrives by post.
Does the codice fiscale card give me health care?
No. The green codice fiscale card is issued only to people who are not entitled to the national health service. For health cover, ask the local health authority (ASL).
How much does it cost?
The form and instructions are free to download and print, and the agency’s pages for this request name no fee.
I lost my Tessera Sanitaria. Do I need this form?
Not necessarily: you can ask for a new one online in the agency’s reserved area with SPID, CIE or CNS. If you cannot, send the AA4/8 with box 5 ticked, reason 1, and a copy of your ID by PEC, or hand it in at an office.
Who signs for a child?
A parent applies for the child (T, code 10), signs, writes their own codice fiscale as the signer and shows their own ID and a proof of the child’s identity.
