Italy VAT API — Validate Italy VAT Numbers in Real Time
REST JSON endpoint for verifying Imposta sul valore aggiunto (IVA) numbers against the official EU VIES register, with national registry fallback where available and a VIES consultation number once you set your own VAT as requester in dashboard Settings.
Why an Italy-Aware VAT API
In Italy, VAT is known as Imposta sul valore aggiunto (IVA) and the current standard rate is 22%. Every Italy VAT number starts with the prefix IT and follows a fixed structure issued by the Italian tax authority. A generic VAT validator that ignores country-specific quirks will accept malformed input, miss the country's format rules, and fail to surface the local registry identifier that accountants and auditors actually need.
The vatnode API normalises IVA input, runs the official VIES check, and returns a single JSON shape with the consultation number, company data where published, and the current Italy VAT rates inline.

Validating Italy VAT Numbers — Code Examples
All three examples validate the same Italy VAT number IT15844561009. To receive a consultation number back, set your own VAT as requester once in dashboard Settings — then every call, including these, returns a consultation number automatically, with no extra parameters.
curl 'https://api.vatnode.dev/v1/vat/IT15844561009' \
-H "Authorization: Bearer YOUR_API_KEY"const res = await fetch(
'https://api.vatnode.dev/v1/vat/IT15844561009',
{ headers: { Authorization: `Bearer ${process.env.VATNODE_API_KEY}` } }
)
const data = await res.json()
console.log(data.valid, data.companyName, data.consultationNumber)import os, httpx
r = httpx.get(
"https://api.vatnode.dev/v1/vat/IT15844561009",
headers={"Authorization": f"Bearer {os.environ['VATNODE_API_KEY']}"},
)
data = r.json()
print(data["valid"], data["companyName"], data["consultationNumber"])What You Get Back
A successful response for a valid ItalyVAT number, once you've set your VAT as requester in dashboard Settings, looks like this:
{
"valid": true,
"vatId": "IT15844561009",
"countryCode": "IT",
"countryName": "Italy",
"companyName": "Gruppo IVA Enel",
"consultationNumber": "WAPIAAAAXk7ZpY3o",
"source": "VIES",
"countryVat": {
"currency": "EUR",
"standardRate": 22,
"reducedRates": [5,10],
"superReducedRate": 4,
"parkingRate": null
},
"verifiedAt": "2026-05-19T08:14:22Z"
}When the number is not registered, valid is false and company fields are null. The consultationNumber is the EU VIES requestIdentifier — the documented audit reference for reverse-charge "reasonable care" evidence. It is returned once you set your own VAT as requester in dashboard Settings; otherwise it is null.
Italy VAT Rates
vatnode returns the current Italian IVA rates inline with every successful response. Today's rates (standard 22%, reduced 5%, 10%, super-reduced 4%) are sourced from the European Commission TEDB feed, checked daily and updated on any change.
| Rate type | Value |
|---|---|
| Standard | 22% |
| Reduced (1) | 5% |
| Reduced (2) | 10% |
| Super-reduced | 4% |
VIES vs National Fallback for Italy
For Italy, VIES is the sole authoritative source. vatnode does not run a national-registry fallback for this country today — when VIES is unavailable, the API surfaces a structured VIES_UNAVAILABLE error with retry guidance so you can degrade gracefully rather than silently accept unverified numbers.
Cached VIES responses (15-minute TTL on identical VAT IDs) absorb the majority of short outages transparently. For the full per-country fallback status, see the coverage matrix.
Italy VAT API — FAQ
Is the Italy VAT number the same as the company registration number?
No. The Italian IVA number is issued for VAT purposes and is distinct from any local company registration number. vatnode returns the IVA number plus, when available, the registry identifier filed with the national company registry.
How fast is Italy VAT validation through vatnode?
Cached responses return in single-digit milliseconds. Live VIES lookups for Italy typically complete in under one second; a 15-minute Redis cache is applied to identical VAT IDs.
Does the API work for Italian sole traders and small businesses?
Yes. If an Italian sole trader or small business is registered for IVA and listed in VIES, vatnode validates the number and returns the same response shape as for corporate entities. The valid field is true regardless of legal form.
Does vatnode handle VIES outages for Italy?
vatnode caches recent VIES responses and surfaces a clear VIES_UNAVAILABLE error code with structured retry guidance. vatnode does not use a national validity fallback for Italy — only the VAT register itself can confirm a VAT registration, so during a VIES outage validation defers to the cached result or returns the error for safe handling.
What is the consultation number returned for checks in Italy?
The consultationNumber is the VIES requestIdentifier — a unique reference issued by the EU VIES service that proves the check was performed against the official EU register on a specific date. It is the EU's documented mechanism for "reasonable care" evidence under the reverse-charge rules and is returned once you set your own VAT as requester in dashboard Settings — including for Italy.
