Received an invoice but worried it might be fake? Our invoice verification tool allows you to input key details such as the invoice code, invoice number, billing date, total amount (including tax), and check code. It then calls the tax data API for real-time comparison to verify the authenticity and status of the invoice within the national tax system. The invoice code is a 12-digit number uniformly assigned by the State Taxation Administration to identify the invoice type and region.
Q: What information is required for invoice verification?
A: The invoice code, invoice number, billing date, and total amount (including tax) are required. The check code should be filled in based on the actual invoice.
Q: What are the possible "invoice statuses" in the verification results?
A: Statuses include Normal, Voided, Red-ink (Credit Note), and Abnormal. A "Normal" status indicates the invoice is authentic and valid.
Please ensure the entered information exactly matches the original invoice. The date format must be YYYY-MM-DD, and the amount should have two decimal places. Results are for reference only; the official tax authority system is the final standard. Avoid transmitting sensitive invoice information over public networks.
For general VAT invoices, the check code is usually located in the remarks column or the bottom right corner. The last 6 digits can be used to improve verification accuracy. For example, by entering invoice code 031001900111, number 12345678, date 2023-10-26, amount 1050.00, and check code 123456, you can verify whether the invoice exists and was issued normally.
