Messaging Compliance in Taiwan
SMS, WhatsApp, voice and RCS rules for businesses messaging customers in Taiwan.
Overview
In Taiwan, marketing messages must respect the Personal Data Protection Act: people must be told how their data is used, and marketing must stop when they object.
The Personal Data Protection Act applies, and Taiwan is setting up a dedicated Personal Data Protection Commission.
Traditional Chinese is the search language and Google is dominant.
WhatsApp's popularity varies across Asia; where it is widely used, Meta's policies and the local data protection law both apply to business messaging.
Some Asian markets operate do-not-call registers for marketing calls and messages, so lists should be checked before voice campaigns.
Advertising Rules
Advertising must follow the Fair Trade Act and the Consumer Protection Act, with clear and truthful claims.

Taiwan has very high smartphone use, and LINE is the dominant messaging app, with LINE Official Accounts widely used by businesses. SMS is common for verification codes and delivery notices.
Cards, LINE Pay, JKOPAY and convenience store payment and pickup are popular. Lunar New Year, the Dragon Boat Festival, Mid-Autumn Festival and the Double 11 online sale are key commercial moments, and traditional Chinese characters are required.
Taiwan is the centre of the global semiconductor industry: TSMC makes most of the world's advanced chips, and electronics companies such as Foxconn, MediaTek, ASUS and Acer are based here. The business tax (VAT) is 5%, and prices are in New Taiwan dollars. Traditional Chinese characters are used, not the simplified characters of mainland China, so copy must be localised rather than converted automatically. The Personal Data Protection Act requires consent or another legal basis for marketing, and recipients can refuse further messages at any time.
