Since January 2020, a valid customer VAT number is a substantive legal condition for zero-rating intra-EU goods supplies — not a best practice. VAT number validation at invoice time is your first line of defence.
Why this matters
During a tax audit, showing that a VAT number was checked and valid at the time of invoice is a legal requirement for zero-rated intra-EU supplies. A boolean result from your own system proves nothing to a tax authority.
vatnode returns the official consultation number issued by the EU Commission — a verifiable reference that shows the check was performed, when, and what the result was. vatnode returns it as part of every qualified validation response.
Why a basic VIES call is not enough
One API call returns validated status, enriched company data, VAT rates, and an audit trail — ready for checkout, invoicing, and B2B onboarding.
National registry fallback via tax authority and company registry APIs keeps validation working even when a country node is temporarily unavailable. Cache hits return in <50ms; live checks in 200–800ms.
Every validation returns an official consultation number from the EU Commission — a verifiable token that proves the check happened at a specific time. Store it alongside your invoices as evidence tax authorities can verify independently.
Subscribe to your customers' and suppliers' VAT IDs. Get a webhook the moment one de-registers — so you fix the next invoice before it goes out wrong, instead of finding out at audit time.
Beyond VIES: registration date, legal form (GmbH, SAS, AB…), and industry code from national registries. Local VAT name, abbreviation, all rate tiers, and currency — in every response.
Where a VAT number belongs to a sole trader, some fields may constitute personal data under GDPR.

vatnode handles VAT validation wherever your business touches an EU counterparty.
Validate a customer's VAT number at checkout to apply the correct reverse charge or tax rate — without blocking the buy button on VIES downtime.
Verify VAT before generating zero-rated intra-EU invoices. Store the consultationNumber alongside your invoice — it's the EU Commission-issued reference that proves the check happened at invoice time.
Confirm a new business customer is registered. Enrich the record with legal form, registry code, and industry from national registries.
Track VAT IDs of active customers and get webhook alerts when a registration becomes invalid between billing cycles — before it surfaces in an audit.
Drop-in integration guides for your language, and dedicated reference pages for every EU member state.
Failed B2B invoices, wrong reverse-charge VAT decisions, and audits you cannot defend — every plan stops all three. Pick a tier based on volume and how often you re-check existing customers.
