What is a provisional tax code
A provisional tax code is a temporary identifier made up of 11 numeric digits, issued by the Italian Revenue Agency (Agenzia delle Entrate) when the definitive 16-character codice fiscale can't be assigned straight away. Think of it as a placeholder. It keeps you visible in the Italian tax system while the paperwork catches up.
The definitive code is built from your personal data — surname, first name, date of birth, gender and place of birth, all encoded into letters and numbers. The provisional version isn't. It's a flat numeric string that means nothing on its own and tells you nothing about the person behind it.
How the 11 digits break down
The provisional tax code uses 11 digits: the first 7 are a sequential number assigned by the Revenue Agency, the next 3 identify the office that issued it, and the last is a check digit that guards against typos.
One thing worth getting straight from the start. A provisional code is real and usable, but it is always meant to be replaced. The moment your records are complete, the Agency swaps it for the permanent alphanumeric code you'll keep for life. Want to see what that final code will look like? Our codice fiscale calculator builds it from the same personal data the Agency uses.
Differences from the definitive tax code
Knowing how the two codes differ saves you a lot of confusion at a bank counter or a hospital desk. They look different, they behave differently, and they unlock very different things.
| Feature | Provisional | Definitive |
|---|---|---|
| Format | 11 numeric digits | 16 alphanumeric characters |
| Encoded data | None | Surname, name, date, place of birth |
| Validity | Temporary | Permanent (lifetime) |
| Health card | Not issued | Issued automatically |
| Can be checked online | Limited | Yes |
Why this matters in practice
The gap isn't only cosmetic. Most government portals and many private systems are wired to expect the standard 16-character format, so they validate against it and reject anything else. A provisional code can quietly fail those checks — no error you'd understand, just a form that won't submit. If you ever need to confirm a definitive code is formally correct, the tax code verification tool checks its structure and check character in seconds.
When a provisional tax code is issued
The Revenue Agency issues a provisional code in a handful of specific situations. The common thread: someone needs a tax identity now, but the data for the permanent one isn't ready yet.
Newborns before registry registration
A baby may need medical care within hours of birth, long before the civil registry has processed anything. To let the newborn be identified in the health system right away, the Agency assigns a provisional code. It bridges those first days.
Foreign nationals waiting on documents
People who've just arrived in Italy often can't wait for a residence permit to be finalised before they start living. A provisional code lets them get moving. With it they can typically:
- Open a bank account
- Sign an employment contract
- Access basic healthcare
- Sign a rental agreement
If this is your situation, our guide on the tax code for foreigners walks through the full process from arrival to definitive code.
Duplicate-code (homonymy) cases under review
Occasionally two people end up assigned the same codice fiscale — a clash the Italian system calls omocodia. While the Agency works out a corrected code for one of them, that person may hold a provisional code in the meantime.
Incomplete or unverified personal data
And sometimes the details on file simply don't add up yet — a misspelled name, a missing birth record, a place of birth that needs checking. Until those are confirmed, a provisional code stands in.
Don't confuse it with a company code
Companies and associations also have an 11-digit tax code — but theirs is definitive and permanent, not provisional. Same length, completely different status.
Validity and duration
How long does a provisional code last? Honestly, there's no fixed clock on it. Its validity simply runs until the definitive codice fiscale takes its place, and the timing depends entirely on how fast the underlying paperwork gets sorted.
Typical duration
There's no statutory expiry date. The code stays live until it's replaced — which sounds reassuring, but leaving it open invites friction down the line with:
- Banking and financial services
- Specialist medical appointments
- Tax filings and returns
- Public-administration online portals
What happens if you wait
A provisional code doesn't technically expire. It just becomes increasingly useless. More and more services will turn it away, and the Agency itself may chase you to convert it after a while. The practical advice is blunt — don't sit on it.
Usage limitations
A provisional tax code is a valid identifier, but it's a stripped-down one. Several doors stay closed until you upgrade to the definitive version, and a few of them are doors you'll want open quickly.
Services you can't reach
- Health card: not issued with a provisional code — see our health card guide
- SPID digital identity: can't be created without the definitive code
- INPS services: many functions are off-limits
- Revenue Agency online: a reduced set of services only
- Electronic Health Record: not accessible
Friction with banks and insurers
Plenty of banks and insurance companies struggle to fit an 11-digit code into systems designed around the 16-character standard. That mismatch can show up as:
- A refused current-account application
- An insurance policy that can't be issued
- Snags with international transfers
The hard limits
- Not usable for a standard income-tax return
- Not valid for claiming tax bonuses or benefits
- Rejected by many bureaucratic procedures
- Awkward for signing up to digital services
Getting your definitive tax code
Moving from a provisional to a definitive code means completing a few steps at the Revenue Agency — or, in some cases, having it happen automatically through your municipal registry. The route depends on why you got the provisional one in the first place.
Documents you'll need
- Valid ID: identity card or passport
- Proof of residence: a residence certificate or declaration of address
- For foreign nationals: a residence permit or the receipt of your application
- For newborns: the birth certificate and the parents' documents
Where to go
- Revenue Agency: any local office
- Your municipality: for certain cases handled through the registry
- Italian consulate: if you're applying from abroad

The conversion procedure step by step
Converting a provisional code into a definitive one follows a defined path. It bends a little depending on your circumstances, but the backbone looks like this.
Steps to convert
- Check that you have every required document in hand
- Book an appointment at the Revenue Agency
- Show up with the originals — copies alone rarely cut it
- Fill out form AA4/8 (for natural persons)
- Wait for the verification and the new code assignment
- Request the health card, if it isn't issued automatically
How long it takes
When the paperwork is clean, the definitive code is usually assigned on the spot. The physical health card is a different matter — it's posted out, and that normally lands within 15 to 20 working days.
Update everything once it's done
The day your definitive code arrives, refresh it everywhere it's on record — bank, utilities, employer, family doctor. Stale codes cause the exact problems you just escaped. Once you have the code, you can also reverse-decode it to double-check the encoded data matches your details.
Frequently asked questions
Is a provisional tax code valid for working?
Yes. You can use a provisional tax code to sign an employment contract. That said, convert it as soon as you reasonably can — leaving it in place tends to complicate tax returns and your INPS contributions later on.
Can I open a bank account with a provisional code?
It depends on the bank. Some accept it without fuss; others insist on the definitive code before they'll proceed. A quick call to the branch ahead of time saves a wasted trip.
How long do I have to convert it?
There's no legal deadline. Even so, the strong recommendation is to convert within a few months, because access to services narrows the longer the provisional code stays active.
Can a provisional code become definitive automatically?
Sometimes, yes — newborns are the classic example, once their registry entry is complete. In other cases you have to ask the Revenue Agency explicitly. When in doubt, assume you'll need to file the request yourself.
Will I get a health card with a provisional code?
No. The tessera sanitaria (Italian health card) is only issued with the definitive code. With a provisional one you can still access essential care, but the physical card and its full benefits wait for conversion.
Does a provisional tax code cost anything?
No. Issuing a codice fiscale, provisional or definitive, is free of charge at the Revenue Agency. If anyone asks you to pay for the code itself, be wary.
Are EU citizens treated differently?
The provisional-code logic is the same, but the documents and timelines can differ. Our guide to the tax code for EU citizens covers those specifics.
