Who regulates A2P SMS in Switzerland?
Application-to-person messaging to Switzerland is overseen by the Federal Office of Communications (OFCOM-CH), which licenses the operators that terminate A2P traffic and sets the conditions those routes run under. BroadNet delivers into Switzerland over direct operator connections — Swisscom, Sunrise and Salt — rather than through resold or grey routes, so the sender ID, the delivery receipt and the audit trail all come back from the licensed path.
- Telecoms regulator: Federal Office of Communications (OFCOM-CH).
- Direct operator routes: Swisscom, Sunrise and Salt.
- Sender-ID registration: Alphanumeric sender IDs allowed without formal registration. German, French, Italian all supported.
- Typical lead time: Free-form.
Sender ID registration in Switzerland
Alphanumeric sender IDs allowed without formal registration. German, French, Italian all supported. Registration is not a formality — an unregistered or mismatched sender ID is the most common reason otherwise-valid traffic is filtered, and the failure is usually silent rather than a hard rejection. Plan Free-form for approval and register before you need the route, not during a launch.
- Lead time: Free-form.
- BroadNet files sender IDs on your behalf through the OFCOM-CH-licensed operators.
- DE / FR / IT: All three official languages supported.
- Time to production: about 5 business days from test access to production.
Consent and content rules
revFADP (Swiss FADP) enforced from 2023. GDPR-equivalent. Transactional messages — one-time passcodes, delivery and account alerts — are treated differently from marketing, but the distinction is decided by the content of the message rather than by how the campaign is labelled.

- Sender ID free: Alphanumeric allowed without formal registration.
What this means for your integration
Practically, three things decide whether traffic to Switzerland performs: a registered sender ID on an OFCOM-CH-licensed route, a consent and opt-out record you can evidence, and message content that matches the category it was registered under. BroadNet's compliance engine checks each submission against the Switzerland ruleset before it reaches the operator, so a non-compliant send is rejected back to you rather than filtered silently downstream — which is the difference between a fixable error and traffic that quietly disappears.
- Every message returns a delivery receipt (DLR); BroadNet does not publish per-country delivery percentages.
- Indicative list pricing: EUR 0.07 – 0.10 per message.
- Addressable mobile base: 11M subscribers.
