Italy VAT number check

Q: Can I check VAT numbers from code or in bulk?

Yes. The same check is available over the REST API (GET /v1/it/vat/{id}) and the MCP server, with the same key as every other country. See the API docs.

Check that a Italy VAT number is well formed and its check digit is right, before you pay or onboard a supplier. Format only

Example: IT00484960588 (Eni). No account needed: 10 lookups a day per network, shared with the keyless API.

What this check tells you

Format only

We check the structure and the check digit published by the issuing authority, offline. That catches typos and made-up numbers. It does not show that the business exists, is registered or is active, so a well-formed number gets review, never pass. To confirm registration, use the official lookup: European Commission VIES VAT number validation.

Italy ID formats we check

ID type	Level	Check digit	API endpoint	Official lookup
VAT Partita IVA (VAT number)	Format only	Luhn	`GET /v1/it/vat/{id}`	European Commission VIES VAT number validation

From code

Same key and quota as every other country. A well-formed request costs one lookup; a source that does not answer returns HTTP 503 and is not counted.

curl "https://taxid.halpii.com/v1/it/vat/IT00484960588" \
  -H "Authorization: Bearer $KEY"

Questions

Does a valid VAT number mean the company exists?

No. This is a format check: it confirms the structure and check digit, not that the business exists or is active. Confirm registration with European Commission VIES VAT number validation.

Where does the data come from?

No registry is queried. The rules come from the issuing authority's published format and check-digit algorithm (Luhn).
