How to check the authenticity of Beijing national tax invoice? There is only the invoice code and invoice number on the invoice, but there is no tax registration number of the seller.
If there is a seller's tax registration number, you can only find out which company bought the invoice, but you can't find out the specific amount and commodity name. You can check it through the national tax network 12366 where the seller is located. Without the tax registration number, all this information can't be found, and both the invoice number and the tax registration number must be available.
