Overview
CLI routes to Switzerland
A CLI route to Switzerland is a wholesale path that keeps the caller ID you send intact all the way to the handset. CLIRoutes only places CLI-tier traffic on paths that passed CLI test calls on Switzerland’s main networks, and removes paths that stop passing.
Swiss CLI routes carry authorised Swiss numbers on paths accepted by Swisscom, Sunrise and Salt anti-spoofing filters. We test each language region’s area codes, because enterprise traffic often spans all three.
Switzerland is a small, high-value destination with four language regions. Traffic is mostly customer care, insurance, banking and B2B, and Swiss consumers are quick to report unwanted calls to SECO.

Dialing & setup
Dialing Switzerland correctly
- Drop the trunk 0: 044 123 45 67 becomes +41 44 123 45 67.
- Four language regions: German, French, Italian and Romansh. Match script language to the area code.
- Switzerland is outside the EU: GDPR does not apply directly, but the revised FADP does.
- Freephone 0800 numbers cannot be reached on international routes.
Caller ID best practice
Present a Swiss number you hold, ideally one matching the language region you call (044 Zurich, 022 Geneva, 091 Ticino). Calls from abroad presenting Swiss numbers that are not legitimately used are filtered by Swiss providers.

What healthy Switzerland traffic looks like
Swiss routes are high quality and relatively expensive. ACD tends to be longer than in neighbouring countries because traffic is mostly service and B2B.

Switzerland CLI routes: FAQ
Can’t find what you need? Our routing team answers within the hour, around the clock.
Do Swiss marketing rules apply to B2B calls?
The directory asterisk applies to business entries too, so scrub B2B lists against it. Unfair-competition rules also apply to aggressive sales methods regardless of the recipient type.
Which area code should I present?
Match the language region where possible: 044/043 for Zurich, 022 for Geneva, 031 for Bern, 091 for Ticino. A local, callable number answers better than a foreign one.
Does Switzerland follow EU telemarketing rules?
No. Switzerland has its own rules: the Unfair Competition Act, the directory asterisk and the revised Federal Act on Data Protection. They are similar in spirit but differ in detail.
Can I call Swiss customers from an EU number?
Yes, and it displays as a foreign number. A Swiss number you hold answers better and avoids anti-spoofing filters that apply to Swiss CLIs on foreign traffic.
How do Swiss providers handle spoofed calls?
They filter calls from abroad that present Swiss numbers without authorisation. Legitimate Swiss CLIs need to be used on paths recognised as authorised.
Which caller ID can I present on Switzerland calls?
Only numbers you own or are authorised to use. Present a Swiss number you hold, ideally one matching the language region you call (044 Zurich, 022 Geneva, 091 Ticino). Calls from abroad presenting Swiss numbers that are not legitimately used are filtered by Swiss providers.
