Example use cases

Vendor onboarding qualification check
“We're onboarding a new Japanese vendor and they gave us their qualified invoice number T1122334455667 — can you confirm it's legitimately registered in the NTA registry and hasn't been cancelled?”
Automated invoice audit for tax filing
“I need to validate the qualified invoice registration number T5556667778889 on this billing document to make sure it's recognized by the NTA before we include it in our consumption tax return.”
Technical details
Endpoint
POSThttps://api.jpverify.com/jp-invoice/verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify a single Japanese qualified-invoice (インボイス) T+13 registration number in real time against the NTA registry, particularly for accounts payable workflows, vendor onboarding, or pre-payment compliance checks. Prefer the batch endpoint for verifying multiple numbers at once. This is the authoritative check for Japan's consumption tax invoice system compliance.
Side effects
- Invalid T-number format (not T followed by exactly 13 digits) — returns validation error
- Number not found in NTA registry — returns not-found status
- Cancelled registration — returns cancelled status with cancellation date
- Network or NTA registry unavailability — service error
- Malformed request body — 400 Bad Request
