What Avatcado is
Avatcado is a VAT and GST number validation API. It covers 32 countries through a single REST endpoint: all EU member states via VIES, the United Kingdom via HMRC, Switzerland and Liechtenstein via the BFS UID Register, Norway via the Brønnøysund Register, and Australia via the ABR. It also exposes VAT rate data, batch and async validation, and typed SDKs for TypeScript and Python.
Who runs it
Avatcado is built and operated by Remco de Jongh through De Jongh Software Development, the Netherlands-registered sole proprietorship behind the product (KVK 84251352).
Why it exists
VIES, the European Commission's VAT validation service, is free but difficult to rely on directly: undocumented rate limits, no SLA, frequent per-country outages, and occasional silent false negatives during degraded service (something we see in our own production monitoring). UK, Swiss, Norwegian, and Australian validation each require a separate integration with a different national registry and response format. Avatcado exists to wrap all of that in one dependable API with caching, automatic retries, and consistent error handling, so developers building billing, checkout, or compliance flows do not have to solve VAT validation reliability themselves.
