vatnode vs VAT API – Validation Primitive or Invoicing Suite
VAT API sells a compliance bundle: EU and UK number validation, rate lookup including by customer IP, currency conversion, and VAT-compliant invoice generation with sequential numbering. vatnode sells one thing – the validation itself, for the EU only, with as much evidence attached to each result as we can get. If the invoice side of your stack is already built, the bundle is weight you carry for nothing. If it is not built, the bundle is doing work you would otherwise do yourself.

Where vatnode Is Stronger
What a single validation returns. Beyond the verdict and the company name and address, vatnode returns registration date, legal form and industry description pulled from national registries, the local VAT name and abbreviation for the invoice line, all four rate tiers including super-reduced and parking, the currency, and a checkId plus verifiedAt to store against the invoice.
Monitoring. Register a customer VAT number and vatnode re-checks it on a schedule, sending a webhook when it goes invalid or when the registered name or address changes. VAT API's public documentation describes request/response validation, not a monitoring layer.
Fallback when VIES is down, with the answering authority named in the source field — with the caveat that a domestic registry confirms domestic registration, not the cross-border VIES result, and carries no consultation number.

vatnode rows come from our own API and pricing page; VAT API rows from its public site and documentation, checked 11 September 2026. Rows marked false mean the vendor does not document the capability publicly, which is not the same as confirming it is absent. Neither vendor publishes an uptime SLA.
Questions Buyers Ask
Does VAT API validate UK VAT numbers?
Yes — it validates against VIES for the EU and HMRC for the UK. vatnode does not. Our scope is the 27 EU member states plus XI (Northern Ireland), which VIES covers under the Northern Ireland Protocol. If you invoice British companies and need their GB numbers checked, that is a straight gap on our side.
Does VAT API return a consultation number?
Yes. Its documentation states that optionally passing your own organisation VAT number makes the validation resource return a unique consultation_number for audit purposes — the same mechanism vatnode uses. The consultation number is not exclusive to any one vendor. The difference is operational: vatnode stores the requester VAT once in Account settings so every check carries it, and refuses to return a verdict without one when a requester is configured, rather than silently answering without the audit reference.
What does VAT API cost?
We could not answer this from public sources. As of 11 September 2026 vatapi.com does not publish plan prices or request quotas on its own site; it offers a 30-day trial and routes purchase through an external checkout. That is not a criticism of the product, but it does mean you cannot price-compare before signing up. vatnode publishes its plans: free at 100 requests a month, €19/month for 1,000, €49/month for 10,000.
Can VAT API generate invoices?
Yes, that is part of its product — VAT-compliant invoice generation with sequential numbering, plus GBP/EUR currency conversion. vatnode does none of that. We validate a number and return structured evidence about it; your billing system builds the invoice. If you want validation and invoicing from one vendor, VAT API covers more of that job than we do.
What happens when VIES is unavailable?
vatnode falls back to the national tax authority or company registry for that country where one is wired up, and names the responding source in the response. That buys availability rather than equivalent proof: a domestic registry confirms local registration, not the cross-border VIES check, and it returns no consultation number. VAT API does not document a national-registry fallback (checked 11 September 2026).
Which one should I pick?
Pick VAT API if you need UK coverage, invoice generation or IP-based rate lookup in the same product. Pick vatnode if your customers are EU-only and you want the validation itself to carry more evidence — registry enrichment, an audit reference per call, and monitoring that tells you when a stored customer number stops being valid.
