Italy VAT number check (Italian Partita IVA)
Check the Italian Partita IVA supplied by the business. Use IT followed by eleven digits, separate the shape check from the VIES response, and keep an unavailable result unresolved.
Italy uses IT followed by eleven digits
Use the Partita IVA supplied by the business. Enter the IT prefix once, then read the VIES response. A plausible shape is not a registration result, and a missing response is not an invalid result.
IT12345678912 — invented example; eleven local digits.
Valid confirms the current intra-EU registration response; invalid or unavailable needs its own next step.
Save the exact identifier, country code, response and check date with the invoice record.
Eurostat reports that Italy's 2025 share of exports to the EU27 was 51.3%; the remaining 48.7% was outside the EU27. This describes trade geography, not VAT demand, a tax rate or the result of an individual check. Source: Eurostat EXT_LT_INTERTRD (2025, Italy).
Italy VAT check questions
What format does an Italian VAT number use?
An Italian VAT number uses the IT prefix followed by eleven digits, for example IT12345678912. The example is invented and illustrates the shape only; it is not a registered number.
Does the IT format prove that the business is registered for EU trade?
No. Eleven digits and an IT prefix are only a format check. VIES must return a current valid response before you treat the identifier as confirmed for intra-EU transactions.
What does an unavailable Italian VIES response mean?
It means VIES or the Italian national registry did not answer that request. Keep the attempt as unresolved and retry later; do not change an unavailable response to invalid.
If the registry does not answer, review the VIES error guide. For a usable response, run the checker below and keep the dated result with the invoice record.
For registration or tax-account questions, consult the Agenzia delle Entrate (Italian tax authority).
What VIES can return
- Valid: the VAT number is currently confirmed for intra-EU transactions.
- Invalid: VIES did not confirm the number as valid at the time of the check.
- Unavailable: VIES or the national VAT registry did not reply.
Before relying on the result
Match the VAT result with your customer's invoice details and keep your own evidence of the check. A valid VIES response is a useful record, but it is not a substitute for your compliance workflow or advice from a tax professional.
If Italy is unavailable in VIES, retry later before treating the VAT number as invalid. Member-state registry outages can look like a failed check even when the number itself is fine.
