FAQ FAQ

DR.WU follows Ministry of Finance's "E-invoice Guidelines" and issues "dual-copy e-invoice" for all purchases made on the website. DR.WU does not mail e-invoices, but uploads invoice numbers onto the website for members' reference.

"DR.WU" will check all e-invoices for lottery winnings as soon as winning numbers are released on the 25th of each month. If you win any of the lottery prizes, our customer service personnel will send winning invoices to you within 7 working days via registered mail.

Important reminder: Winning invoices are mailed to the purchaser's address, so please make sure that the purchaser's address is correct. You will be deemed to have forfeited your prizes if you provide a wrong address that prevents the winning invoice from being mailed to you.

Hard copy invoice will be mailed after the 7-day cooling-off period, or approximately 10 working days after shipment.

According to Regulations Governing the Use of Uniform Invoices, invoices can be re-issued only in the case of error. An invoice can not have the buyer changed from an individual to a corporate entity, or from a corporate entity to an individual. Once an invoice has been issued, the seller can not alter buyer's name or business ID without valid cause, and re-issuance of invoice under a different name or business ID at buyer's request is prohibited.

According to the current electronic payment settlement process, only one invoice is issued per order, and we regret that we are unable to issue multiple invoices at request.

E-invoices are issued according to the latest format published by the Ministry of Finance, and the standard format currently does not show buyer's name on the customer copy. We regret that we are unable to re-issue an e-invoice that shows buyer's name. Please contact Online Customer Service Center if you have further queries, and a dedicated officer will be assigned to serve you. (Service hours: 09:00-18:00, Monday through Friday)
