Messaging Compliance in Switzerland
SMS, WhatsApp, voice and RCS rules for businesses messaging customers in Switzerland.
Overview
In Switzerland, mass advertising by SMS or email without prior consent is unfair competition under Article 3(1)(o) of the Federal Act against Unfair Competition (UWG/LCD). Messages must identify the sender and offer an easy opt-out, with a limited exception for existing customers.
The revised Federal Act on Data Protection (FADP), in force since September 2023, applies, overseen by the Federal Data Protection and Information Commissioner (FDPIC).
Switzerland is multilingual: German, French and Italian regions search in their own language, so national campaigns often need two or three language versions.
In Europe, WhatsApp marketing is treated like other electronic marketing: you need a lawful basis, usually consent, and you must be transparent about how contact data is used under GDPR or UK GDPR.
European countries regulate marketing calls through national laws and do-not-call or objection registers, and automated (recorded) marketing calls generally require prior consent.
Advertising Rules
Advertising should follow the UWG and the principles of the Swiss Commission for Fairness, including clear labelling of commercial content.

Switzerland has one of the highest smartphone penetration rates in Europe, and WhatsApp is the dominant messaging app, while SMS remains common for transactional messages and two-factor authentication. Campaigns usually need German, French and Italian versions depending on the canton.
TWINT is the leading mobile payment app, used by millions of Swiss residents in shops and online, alongside cards and invoice payment. Prices are high and consumers expect premium quality, precise information and discretion. Key dates include Christmas and Advent, Black Friday, summer holidays and regional carnivals such as Basel Fasnacht, and many businesses close on Sundays.
Switzerland's economy includes banking, insurance, pharmaceuticals (Roche, Novartis), watchmaking, food (Nestlé) and tourism. VAT is 8.1%, and prices are in Swiss francs. German, French, Italian and Romansh are official languages, so campaigns must use the right language for each canton. TWINT is the most popular mobile payment app.
Regulators, Registers and Practical Rules in Switzerland
Switzerland's revised FADP applies since September 2023, and the Unfair Competition Act requires consent for mass advertising.
The Federal Data Protection and Information Commissioner (FDPIC) supervises data protection. Messages should be in the language of the region.
Swisscom, Sunrise and Salt are the operators. TWINT is widely used.
In practice, Swiss customers expect very accurate prices including VAT, and messages in the wrong national language feel careless. Keep consent records and offer a simple opt-out in each message.
