Output
Returns a batch of verification results for up to 10 queries, each indicating whether the submitted company name, corporate number, or address matches the official NTA registry record, along with the canonical registered name, corporate number, and address from the NTA database, plus a per-entry match status.
Example use cases
Vendor onboarding compliance screen
“I need to onboard 8 new Japanese suppliers — can you verify all of them against the NTA corporate registry at once? Here are their company names and 13-digit corporate numbers: [list]. Flag any that don't match the official registration.”
KYB due diligence on investment targets
“We're evaluating three potential Japanese business partners for a deal. Can you check Recruit Holdings Co Ltd, Z Holdings Corporation, and LINE Corporation against the NTA registry and confirm their corporate numbers and registered addresses are valid?”
Accounts payable fraud prevention
“Before we process these invoices, can you verify that these 6 Japanese companies actually exist in the NTA database? I have their names and addresses from the invoices and want to make sure none of them are fake or mismatched.”
Technical details
Endpoint
POSThttps://api.jpverify.com/jp-company/verify-batchWhen to prefer
Choose this endpoint when you need to verify multiple Japanese companies in a single round-trip rather than making individual calls per company. Ideal for compliance workflows, vendor onboarding, or KYB due diligence where you have 2–10 Japanese entities to validate simultaneously. Prefer the single-entity endpoint for one-off lookups, and this batch endpoint when processing lists to minimize cost and latency per verification.
Side effects
- Batch exceeds 10 entries — API rejects with validation error
- Corporate number format invalid (not 13 digits) — entry-level error returned
- Company name not found in NTA registry — returns no-match status rather than error
- NTA registry temporarily unavailable — service error or timeout
- Malformed request body — 400 bad request
- Payment not authorized — x402 payment required error
- Partial batch success — some entries match, others return no-match
