Use the free single-check endpoint below, or get one API key that validates EU VAT (VIES) and EORI (TAXUD) together — a live, self-serve product with a free tier.

What is available today

The free endpoint below accepts one VAT number per request and returns a live VIES result. It has no API key, uptime SLA, or commercial support commitment.

For automation there is now a live, self-serve API: one key validates both EU VAT (VIES) and EORI (TAXUD), metered with a free tier (100 checks per month) and paid plans from €19/month for higher volume, CSV batch, and dated audit records. Keys issue instantly — no sales call.

No VAT numbers are retained longer than needed unless you explicitly opt into an audit-history product.

Building on the official VIES service

The official VIES technical service exposes VAT validation through a SOAP interface used by many VAT checker tools. A typical check sends a member-state country code and a VAT number, then receives valid, invalid, or error responses. It can also expose approximate checks for workflows that include requester details and may return a request identifier.

Build for downtime, member-state failures, timeouts, and concurrency limits from day one. Avoid storing VAT numbers unless you have a clear user-facing retention purpose and privacy controls.

The metered endpoints below already absorb that work: retries, normalized error states, and a 24-hour cache on upstream responses.

Single-check API quickstart

Send a VAT ID to the same validation route used by the free checker. A successful response reports valid or invalid; upstream or capacity failures return unavailable and should be retried later.

cURL

curl -X POST https://vatvalidate.eu/api/validate \
  -H "Content-Type: application/json" \
  -d '{"vatId":"DE123456789"}'

Server-side JavaScript

const response = await fetch(
  "https://vatvalidate.eu/api/validate",
  {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({ vatId: "DE123456789" })
  }
);

const result = await response.json();

Example response shape

{
  "status": "valid",
  "countryCode": "DE",
  "vatNumber": "DE123456789",
  "requestDate": "2026-07-16",
  "name": "Example company",
  "address": "Example address",
  "source": "VIES",
  "message": "VIES currently confirms this VAT number..."
}

Example only. Company details depend on the member-state response. A VIES result is point-in-time evidence, not tax or legal advice.

Your first metered call

The quickstart above uses the free endpoint, which takes no key. This one uses your key against the metered endpoint — the same route /bulk uses. Your key stays in this browser.

The same call, to take away

curl "https://eoricheck.com/v1/vat?number=NL822010690B01" \
  -H "Authorization: Bearer ek_your_api_key"

Check your remaining quota any time with curl "https://eoricheck.com/v1/usage" -H "Authorization: Bearer ek_...". A VIES result is point-in-time evidence, not tax or legal advice.

Live API · one key

One key validates VAT and EORI

Automating VAT checks? The same VIES validation runs behind a metered API that also validates EU EORI numbers against TAXUD — one key does both. Start free, upgrade when you need batch volume and dated audit records.

  • Free tier: 100 validations per month, no card
  • One key validates VAT (VIES) and EORI (TAXUD)
  • JSON responses with per-key quota and rate limits
  • CSV batch and dated audit records on paid plans (€19 / €49 / €99)
