EU VAT Number Validator — VIES Bulk Check

Validate EU VAT numbers in bulk against VIES, the European Commission's official VAT Information Exchange System. For every VAT ID you get back whether it is valid right now, plus the registered company name and address — the two things you need for reverse-charge invoicing, tax compliance and B2B customer verification.

Paste a list, get a clean dataset. No manual lookups, no captchas, no rate-limit babysitting.

What you get

Real output example:

{
  "input": "IE6388047V",
  "countryCode": "IE",
  "vatNumber": "6388047V",
  "checked": true,
  "valid": true,
  "companyName": "GOOGLE IRELAND LIMITED",
  "companyAddress": "3RD FLOOR, GORDON HOUSE, BARROW STREET, DUBLIN 4",
  "checkedAt": "2026-08-17T01:48:58.067Z",
  "error": null
}

Field	Meaning
input	The VAT ID exactly as you sent it
countryCode / vatNumber	Parsed country prefix and number
checked	true when VIES gave a definitive answer
valid	Whether the VAT number is currently valid
companyName / companyAddress	Registered business behind the number (when the member state discloses it)
checkedAt	Official VIES request timestamp — keep it as your compliance proof
error	Reason when a number couldn't be checked

Formats are forgiving: IE 6388047V, ie-6388047v and IE6388047V all work. Greek numbers are accepted as both GR and EL. Northern Ireland (XI) is supported.

How to use it

1. Paste your VAT IDs (one per line) into VAT numbers.
2. Run the actor.
3. Export the dataset as CSV/Excel for your accounting team, or consume it via API.

Works great on a schedule — e.g. re-validate your whole customer base monthly, since VAT registrations expire and change.

Pricing

Pay per event: a small start fee plus a fee per completed check (valid or invalid — both are definitive answers). Numbers that can't be checked because a member state's service is offline are not charged.

Scenario	Approximate cost
50 VAT numbers	~US$ 0.41
200 VAT numbers	~US$ 1.61
1,000 VAT numbers	~US$ 8.01

FAQ

Is this the official source? Yes — every check hits the European Commission's VIES service directly. This actor adds the bulk handling, parsing, retries and clean output on top.

Why does a number show checked: false? Occasionally a member state's database is temporarily offline (MS_UNAVAILABLE). Those rows are not charged — re-run them later.

Can I use the result as proof for reverse-charge invoicing? The output includes the official VIES request timestamp (checkedAt). Most EU tax authorities accept a VIES check record as evidence of due diligence — confirm specifics with your accountant.

Honest limitations

• Some member states (e.g. Germany and Spain in many cases) do not disclose company name/address — valid still works, but those fields come back null.
• VIES enforces fair-use rates; the actor throttles itself, so very large lists take proportionally longer.
