SMS Compliance in Taiwan
A practical overview of the rules that affect SMS messaging and marketing in Taiwan, with a checklist before you launch.
Key Rules for SMS in Taiwan
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.
Several Asian markets require sender ID registration (for example Singapore's SMS Sender ID Registry) and have data protection laws with marketing consent rules, such as Singapore's PDPA and Malaysia's PDPA.
Data Protection
The Personal Data Protection Act applies, and Taiwan is setting up a dedicated Personal Data Protection Commission.
Keep a record of how each contact was collected, what they agreed to and when, and make it easy for them to withdraw consent.
Practical Checklist
- Collect and record consent (or confirm an existing customer relationship) before sending, with the date and source.
- Use a registered sender ID or number that recipients can recognise as your business.
- Identify your business in every message and keep promotional and service messages separate.
- Give a simple way to opt out of marketing and process opt-outs quickly across all your systems.
- Send in the recipient's local daytime hours and keep frequency reasonable.
Contact data
Format numbers in international E.164 format with the +886 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Taiwan follows the Asia/Taipei time zone (UTC+08:00 in October 2026). The usual working week is Monday to Friday. Schedule SMS campaigns for the recipient's local daytime hours, avoid public holidays and religious observances that matter to your audience, and convert send times from IST before scheduling.
In Taipei, customers commonly use Mandarin (Traditional Chinese). Messages in the customer's preferred language usually perform better, but check how local-language text affects character counts (for SMS) and template approval (for WhatsApp).
Digital Habits and Channels in Taiwan
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.
Regulators, Registers and Practical Rules in Taiwan
Taiwan's Personal Data Protection Act is being brought under a new independent Personal Data Protection Commission, and the NCC regulates telecoms. Chunghwa Telecom, Taiwan Mobile and FarEasTone are the operators. LINE is the dominant messaging app.
Sender IDs and links in SMS are scrutinised because of anti-fraud rules, and the Anti-Fraud Act of 2024 adds duties for telecom and platform companies. Messages should be in Traditional Chinese.
Chunghwa Telecom, Taiwan Mobile and FarEasTone are the operators.
In practice, Taiwanese customers are cautious about links in SMS because of fraud, so use a recognisable brand name and well-known domains, and offer a LINE official account as an alternative channel.

Advertising Alongside Messaging

SMS in Taiwan: FAQs
Do I need consent to send marketing SMS messages in Taiwan?
In most cases, yes, or at least an existing customer relationship and a clear opt-out. 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.
