Invoice Verification | Complete Guide to Duplicate Checking and Authenticity Verification: Official Methods + Smart Tools for One-Click Risk IdentificationPublished: 2025-04-18 16:22 Issuing invoices is easy, but verifying authenticity is hard—with the spread of electronic invoices, new scams such as PS tampering, cloned printing, and yin-yang invoices keep emerging. Today Kailing Technology We will teach everyone multiple official verification methods, as well as an ultimate tool that 'produces results in seconds,' to help you easily say goodbye to the trouble of fake invoices.

Log in to the official website: After entering the URL, click "Install Root Certificate for First Verification" (otherwise errors may occur).

Verification code: enter a case-insensitive combination of English letters and numbers (e.g., a4X9) or Chinese characters. 4. Query results: A genuine invoice will display "number of verification attempts + invoice details"; a fake invoice will prompt "no such invoice found" (the invoice is fabricated) or "inconsistent" (information such as invoice number and total amount including tax was entered incorrectly).
