How this service works
Batch EU EORI validation via official EC EOS (up to 100 per request)
Output
For each EORI number in the input array, the endpoint returns a validation result including: whether the number is valid/invalid per the official EC EOS registry, the registered company name (when disclosed by the registry), and the registered address (when disclosed). Results are returned as an array corresponding to the input order.
Example use cases
Supplier onboarding EORI compliance check
“I need to verify the EORI numbers for all the new suppliers we're onboarding this quarter — here's the list: GB123456789000, NL999999999B01, DE123456789, FR998877665. Can you check which ones are valid and pull back the registered company names?”
Freight forwarder customs document audit
“Before we file these customs declarations, can you batch-check these EORI numbers to make sure they're all active and registered: PL1234567890, ES12345678A, IT12345678901?”
KYB due diligence on EU trading partners
“As part of our KYB process for these five EU counterparties, can you validate their EORI numbers — BE0123456789, CZ12345678, HU12345678901, RO123456789, SK1234567890 — and tell me which ones come back with a name and address?”
Technical details
Endpoint
POSThttps://api.wsystem.dev/eori/batch?utm_source=zero.xyzWhen to prefer
Choose this batch endpoint over the single EORI endpoint when you need to validate two or more EORI numbers in one operation, reducing latency and per-call costs for bulk compliance workflows. Prefer this over building your own scraper against the EC EOS portal when you need programmatic, structured results. Ideal for KYB pipelines, freight/customs onboarding, and supplier due diligence where lists of EORI numbers need fast, authoritative validation.
Side effects
- Invalid EORI format in input array — individual item flagged as invalid rather than whole request failing
- EC EOS registry temporarily unavailable — upstream timeout error returned
- Empty array submitted — likely returns empty results or validation error
- Non-EU EORI formats may not be recognized by the underlying registry
- Payment failure (x402) — call blocked if USDC payment not processed
