Core Viewpoint - Personal consumers generally do not need to provide their ID number when requesting an invoice, except in specific cases related to electronic invoices [2][4]. Policy Regulations - According to the National Taxation Administration's notification, personal consumers do not need to provide taxpayer identification number, address, phone number, bank account, or other identification when requesting a VAT ordinary invoice [2]. - However, if an electronic invoice is requested and needs to be displayed in the personal invoice folder, the consumer must provide their name and ID number [2]. Personal Invoice Folder - The personal invoice folder allows individuals to manage their electronic invoices through the personal income tax app, where they can view, export, or refuse invoices obtained from the electronic invoice service platform [3]. Practical Implications - When purchasing items, if a consumer does not wish to disclose their ID number, they can still receive a VAT ordinary invoice. However, to view this invoice in their personal invoice folder, they must provide their name and ID number [4]. - Consumers can decide whether to provide their ID number based on their need to collect the invoice in the personal folder [5].
