I need to search for an invoice on the VNPost Invoice Information Portal. What information do I need to provide to search for an invoice, and how do I get the 'Mã xác thực' (Authentication code) to complete the search?
Navigate to 'https://hoadon.vnpost.vn/' Locate the 'Tìm kiếm hóa đơn' (Search invoice) form. Identify the required fields for searching an invoice. Determine the type of information required for each field. Specifically, ascertain how to obtain the 'Mã xác thực' (Authentication code). Formulate an answer describing the required information and the mechanism for the authentication code.
State that two pieces of information are required: an invoice lookup code and an authentication code. State that the invoice lookup code field is labeled 'Nhập mã tra cứu hóa đơn'. State that the authentication code field is labeled 'Mã xác thực'. Explain that the 'Mã xác thực' (Authentication code) is obtained from a captcha image displayed on the page.
