In the past, invoices were all stamped with special invoice seals. Whether they can be used depends on whether there is such a seal. However, with the development of the times, this chapter is no longer a "necessity", and many times we only see an electronic signature on the invoice. Faced with this situation, don't worry too much. As early as 2020, the state clearly stated in the announcement that ordinary invoices issued through the VAT electronic invoice platform use electronic signatures instead of special invoices. The actual effect is the same as the stamped invoice, and there is no difference.
2. How to check?
If you are still worried about the authenticity of the invoice, you can inquire through the VAT electronic invoice service platform. There are special electronic invoice styles on the website, which can be directly compared. Generally speaking, this kind of electronic invoice is in OFD format. We can download the invoice format file reader from the website, consult the existing electronic invoices, enter the time and invoice type, and then we can directly query the information of the invoices that have been issued. Format file provides two options: query and download, which is convenient for people to operate. If the invoice is often used or operated, it is recommended to download it, which will be much more convenient to encounter similar things in the future.
