vatnode vs Vatstack

Vatstack validates the number and stops. vatnode returns everything you need to issue a legally compliant invoice — local VAT name, abbreviation, all rate tiers, currency — in a single API call.

countryVat block not returned by Vatstack — only available in vatnode

Vatstack does not return vatName, vatAbbr, superReducedRate, parkingRate, or currency in the validation response. You maintain a separate lookup table or make a second API call.

Granular webhook events

vatnode fires specific events — not just "something changed". Subscribe to any VAT number and get notified precisely:

VAT_BECAME_INVALID

Customer's VAT registration lapsed — stop applying reverse charge immediately

VAT_BECAME_VALID

Previously invalid number reactivated — update invoice settings

COMPANY_NAME_CHANGED

Legal name changed — update your customer records and invoices

COMPANY_ADDRESS_CHANGED

Registered address changed — update your records for compliance

German BZSt fallback

When the German VIES node is rate-limited or unavailable, vatnode automatically retries against the Bundeszentralamt für Steuern (BZSt). Your integration keeps working without any retry logic on your side. The response shows "source": "BZST" so you know which authority answered.
