Generally, the mobile phones provided by physical stores are shopping receipts. If most stores need invoices, they need to take the initiative to ask for them, which are generally divided into electronic invoices and paper invoices. E-invoice inquiry will generally be sent to your mobile phone or email address.
If the invoice has been issued and you want to check the authenticity of the invoice, you can go to the national VAT invoice inspection platform in State Taxation Administration of The People's Republic of China, China, enter the invoice information and check it.
