1. Every ordinary VAT invoice has an invoice code and an invoice number, with 12 digits as the invoice code and 8 digits as the invoice number. First, see if there are such two sets of figures on the invoice;
2. Each invoice shall be stamped with the taxpayer's invoice special seal of the billing unit, with the taxpayer identification number printed on it, which is generally 15 to 18 digits;
3. You can take the invoice to the collection and management department of the competent national tax authority or the ticket department of the billing unit to help identify the authenticity.
To check the authenticity of the invoice, the following conditions need to be met:
1, valid invoice. Before checking the authenticity of invoices, it is necessary to ensure that the invoices held are valid and have not been cancelled. If the invoice has been cancelled, the inspection result will prompt that the invoice has been cancelled, and it is impossible to check the authenticity;
2. Correct the invoice information. It is necessary to accurately enter the invoice code, invoice number, invoice date and verification code of the invoice to ensure the accuracy of the inspection results. If the input information is wrong, the inspection result will be wrong;
3. Internet connection. Checking the authenticity of invoices requires online operation, so a reliable Internet connection is required. If the network connection is unreliable, the inspection may fail or the inspection result may be inaccurate;
4. View the platform or APP. You need to visit the "National VAT Invoice Inspection Platform" in official website, State Taxation Administration of The People's Republic of China, People's Republic of China (PRC), or download and install an APP that supports invoice inspection function, so as to check the authenticity of invoices.
To sum up, different countries or regions may have different conditions and requirements when checking the authenticity of invoices, so it is necessary to know the relevant local regulations and requirements before the specific operation. At the same time, the results of checking the authenticity of invoices are for reference only. If in doubt, it is recommended to consult the relevant tax authorities or apply for a review.
