REST API · 27 member states

One VAT number. The whole company. One call.

Vatlas turns an intra-community VAT number into a full company record: legal name, national identifier, legal form, status and address. The official registers are imported on our side, so the answer comes back in milliseconds — not seconds.

Samples:

Under the hood

Fast because the data is already here

VIES is authoritative, but it is far too slow — and far too often unavailable — to sit on the critical path of a checkout. So we only ask it as a last resort.

Local database

One indexed read on (country_code, vat_number) across the national registers we bulk-import. That is the common case, and it costs a few milliseconds.

Source API

For countries with no usable bulk file — Poland, for one — the call goes out to the administration and the answer is written to our database. The second call is local.

VIES fallback

Everything else goes to the European service, then into a cache. SOAP faults are retried: an outage is never read as a "no".

One envelope only

Local database, national source or VIES: the JSON is identical. meta.checked lists the sources actually consulted, so your client never has to guess.

Offline validation

Syntax for all 27 member states, plus checksums for France, Finland and Poland. A malformed number is rejected in 2 ms and costs no quota.

Errors that mean something

"Not registered for intra-community trade" is not "company does not exist", and "source unavailable" is not a negative answer. Three distinct codes.

Coverage

The whole Union, eight sources of our own

VAT numbers from all 27 member states are validated and resolved. Eight countries are served straight from their official register, imported or queried on our side.
