How this service works
Batch EU company registry lookup in official business registers (up to 25 queries per request)

Example use cases
Supplier onboarding VAT batch check
“I have a list of new EU suppliers I need to onboard — can you validate all their VAT numbers at once: DE123456789, FR98765432100, and IT12345678901?”
Customs EORI compliance batch verification
“Before I ship to these three EU importers, can you batch-verify their EORI numbers — GB123456789000, DE1234567890, and NL123456789 — to make sure they're all valid?”
KYB due diligence for multiple companies
“I'm running due diligence on five potential EU business partners and need to validate their VAT numbers in one go — can you batch check BE0123456789, ES12345678A, PL1234567890, IT01234567891, and AT12345678?”
Technical details
Endpoint
POSThttps://api.wsystem.dev/company/batch?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate multiple EU VAT or EORI numbers in a single API call rather than making individual requests per number. Ideal for supplier onboarding pipelines, customs compliance workflows, or KYB processes that deal with lists of EU companies at once.
Side effects
- Invalid VAT format returns invalid status rather than an error
- VIES service temporarily unavailable causing lookup failure
- Unsupported country code in query
- Batch limit exceeded causing rejection
- Malformed query array returns 400 error
- Payment not processed (x402) resulting in 402 response
