From Green County, Wisconsin, where roughly one resident in seven reports Swiss roots, to American families with a son or daughter working in Zurich or Geneva, calls to Switzerland run on strict ten-digit numbers, four national languages and a new check that flags foreign calls pretending to be Swiss.

To reach a Switzerland number from the United States, dial these three parts in order.
011 41 78 123 45 67
From any mobile, anywhere in the world, you can dial +41 78 123 45 67 instead. Press and hold 0 to type the +, and the phone picks the right access code for wherever you are.
Numbers in Switzerland are written locally with a 0 in front, like 078 123 45 67. Calling from abroad you leave that 0 out, so it becomes +41 78 123 45 67.
A Switzerland mobile number is 9 digits after +41. If a call does not connect, count the digits first.
Only the first part changes. Your access code replaces the 011, then 41 and the number stay exactly the same.
A ~ means wait for the second dial tone before dialing the rest. It is not a digit you press.

About 861,000 Americans (861,324 in the 2024 American Community Survey) report Swiss ancestry - Census Reporter. The largest numbers live in California, Pennsylvania, Ohio and Wisconsin, while Utah has the highest share, about 1% of its population - Census Reporter. Green County, Wisconsin is the most Swiss county in the country at 13.6%, ahead of Holmes County, Ohio (10.8%) and Adams County, Indiana (9.3%) - Census Reporter. Green County is home to New Glarus, founded as a Swiss colony, Adams County to the town of Berne, and Holmes County to Swiss Amish and Mennonite families, while Mormon converts who settled in Utah fill out the rest of the map - Swiss Americans.
Switzerland's own diaspora adds a second, more recent stream. The Swiss foreign ministry counted 80,218 Swiss nationals with permanent residence in the United States in 2015, and in 2010 two-thirds of the Swiss citizens living in the US held dual citizenship - Swiss Americans. Many of these families have one foot in each country, with relatives on Swiss mobiles and business with Swiss offices.
Calls out of Switzerland start with 00, or + on a mobile, and a landline can still prefix a call with a carrier-selection code in the 107xx or 108xx ranges - Wikipedia. That habit has nearly vanished: OFCOM counted fewer than 3,000 manual call-by-call customers in 2022, the last year it reported a figure - OFCOM. The everyday destinations follow the languages spoken at home. Besides Swiss German (55%), French (23%), Standard German (12%) and Italian (8%), the non-national languages people most often use with family are English (7%) and Portuguese (4%), and English, Albanian and Portuguese are the most common non-national main languages - Federal Statistical Office. Those languages point to the family ties behind much of the international calling: Germany, France, Italy, Portugal, the English-speaking world and the Albanian-speaking Balkans.
One destination is easy to mistake for a domestic call: Liechtenstein. It used the Swiss plan under 075 until 5 April 1999, when it adopted its own +423, and from Switzerland it is now dialed 00423 plus seven digits - Wikipedia.
Dial the exit code: 011 from a US or Canadian phone, or + on a mobile or browser dialer.
Dial Switzerland's country code, 41.
Drop the leading 0: the mobile 078 123 45 67 becomes 78 123 45 67, and the Zurich number 044 123 45 67 becomes 44 123 45 67.
Dial the remaining 9 digits, so the full call is 011 41 78 123 45 67, or +41 78 123 45 67 on a mobile.
For Liechtenstein (Vaduz and the rest of the principality), use country code 423 instead of 41.
Drop the trunk 0 after +41. Every Swiss mobile and landline number is 9 digits after +41, so a quick count catches most errors, and the area code is always part of the number, even for local calls, since 29 March 2002 - Wikipedia. Zurich's old 01 is now 044 or 043. Liechtenstein is +423, not +41 - Wikipedia. 0868 test numbers cannot be reached from abroad, and the free-call promise of 0800 numbers does not necessarily apply to calls from the US - OFCOM.
Calls from abroad that show a Swiss number are now checked. Under the fourth edition of Switzerland's rules on calling-line identification, transit carriers must mark incoming calls from abroad that carry a Swiss number, for landline numbers since 1 January 2026 and for mobile numbers since 1 July 2026. If such a call cannot be identified, the caller number is removed, and the receiving provider may strip the number or block the call entirely - OFCOM. A call from the US that shows a US number is unaffected, but an app that dresses your call up with a Swiss number may arrive anonymous or not at all.
Sales calls are policed, and phones may be filtered. Anyone who does not want advertising calls can mark their directory entry with an asterisk, and marketing calls to that number then break the Unfair Competition Act - SECO. Providers must also give customers a tool against unlawful advertising calls, usually a filter that customers switch on themselves unless the provider has enabled it by default, although OFCOM notes that spoofing limits what filters can do - OFCOM. An unannounced call from an unfamiliar foreign number competes with all of that, so a short message saying who is calling and when is worth sending first.
Free and special numbers behave differently from abroad. OFCOM says calls to 0800 numbers are free, except that an extra charge may apply when calling from a call box or from abroad, and 0840, 0842, 0844 and 0848 are shared-cost numbers with a uniform tariff across Switzerland - OFCOM. 0900, 0901 and 0906 are premium-rate lines, and 0868 test numbers cannot be reached from abroad at all - Wikipedia.
Old address books hold numbers that no longer exist. Switzerland merged many area codes in 1996, folding Fribourg's 037 into 026, Neuchâtel's 038 into 032 and Zug's 042 into 041, then made the area code compulsory even for local calls on 29 March 2002; Zurich's old 01 later gave way to 044 and 043 - Wikipedia. A number copied from an old letter with one of these codes needs to be looked up again before you dial it.
Switzerland runs a closed numbering plan: every ordinary number has ten digits, written 0xx xxx xx xx, and since 29 March 2002 the area code must be dialed even for a call next door - Wikipedia. The three digits after the 0 are the national destination code, which is a region for landlines (044 Zurich, 022 Geneva, 031 Bern, 091 Ticino) or a network for mobiles (075 to 079). OFCOM's recommended style is +41 32 765 43 21 internationally and 032 765 43 21 at home - OFCOM.
Because the length never varies, Swiss numbers are easy to sanity-check: after +41 a mobile or landline always has 9 digits, whether you are calling a mobile in Lausanne or a farmhouse in Appenzell. The geography is looser than it looks, though. The 2002 plan has allowed geographic numbers to move between zones, with Bern to Geneva as OFCOM's own example, although providers are not obliged to offer it - OFCOM. An 031 number is therefore a strong hint of Bern, not proof.
Switzerland has four national languages, and the voice that answers usually matches the area code. At home or with friends and family, 55% of people usually speak Swiss German, 23% French, 12% Standard German and 8% Italian - Federal Statistical Office. Expect Swiss German on 044 Zurich, 031 Bern, 041 Lucerne and 061 Basel numbers, French on 022 Geneva and 021 Lausanne, and Italian on 091 Ticino; Romansh, the fourth national language, is spoken by a small minority in Graubünden, the 081 Chur region.
English goes further than many callers expect. 7% of people use English at home or with family, 41% of employed people use more than one language at work every week, and English is the language most often learned in every language region - Federal Statistical Office. Opening in English and asking whether the other person prefers German, French or Italian is a polite and practical approach, and it helps in officially bilingual places such as Biel/Bienne on 032, where either language may come first.
Three networks dominate Swiss mobile phones. At the end of 2024, Swisscom had 53.1% of mobile customers, Sunrise 23.6% and Salt 17.7%, with all others sharing 5.5%, out of 11.9 million mobile customers, about 132 for every 100 residents - OFCOM. The original prefixes still hint at the network: 075 and 079 are Swisscom, 076 Sunrise, 078 Salt and 077 a mix of smaller brands, but numbers can be ported between operators, so an NDC does not prove who serves the line today - Wikipedia.
The landline is shrinking but far from gone. OFCOM counted about 2.81 million fixed telephony contracts at the end of 2024, 2.3% fewer than a year earlier, and it now counts all of them as internet-based (VoIP) access rather than the old analog and ISDN lines. Swisscom (40.5%) and Sunrise (33.2%) hold most of that fixed market - OFCOM. A home number is therefore still worth trying when a mobile goes unanswered.
Liechtenstein looks Swiss on a map and uses the Swiss franc, but its phones are separate. It was part of the Swiss numbering plan under 075 until 5 April 1999, when it adopted its own country code +423, and calls from Switzerland now need the international prefix 00423 and a seven-digit number - Wikipedia. From the US, a Vaduz number is dialed 011 423 plus seven digits, with no trunk 0 and no area code, and entering it under +41 will fail.
The German exclave of Büsingen am Hochrhein, surrounded by Swiss territory, works the other way around. Residents can be reached on a German +49 number, a Swiss +41 number or both, depending on which providers they use, and homes generally have phone sockets for both countries - Wikipedia. If a Büsingen contact gives you a number, check which country it belongs to before dialing: a Swiss one follows the ten-digit Swiss format under +41, a German one the German format under +49.
Plan business calls for weekdays. Swiss labor law prohibits employing staff between 11pm Saturday and 11pm Sunday in principle, with exceptions only under specific conditions, and Sunday shop opening is left to cantonal laws built around public rest - SECO. Offices, banks and most government services are therefore a Monday to Friday call, while Sunday is a good day to reach family at home.
Many large employers and federal offices use 058 numbers, a range reserved for business networks - Wikipedia. The federal metrology institute METAS, for example, publishes +41 58 387 01 11 - METAS. Dial them like any Swiss number: +41, then 58 and the remaining seven digits. Treat 0800 and 084x lines with more care: OFCOM describes 084x tariffs as uniform for callers anywhere in Switzerland and warns that an extra charge may apply to 0800 calls from abroad - OFCOM, so prefer a published geographic or 058 number when one exists.
Yes. Every Swiss number is written with a leading 0 that you replace with the country code: 044 123 45 67 becomes +41 44 123 45 67, and 078 123 45 67 becomes +41 78 123 45 67 - Wikipedia. From a US landline, dial 011 41 first. After +41 there are always exactly 9 digits, for mobiles and landlines alike.
Look at the three digits after the 0. 075 to 079 are mobile networks, with 075 and 079 originally Swisscom, 076 Sunrise and 078 Salt, while codes such as 044, 022 and 091 are regional landlines and 058 belongs to business networks - Wikipedia. Numbers can be ported between operators, so the prefix may not show the current network, but the dialing is identical either way.
No. Liechtenstein used the Swiss plan under the old 075 code until 5 April 1999, when it adopted its own country code +423 - Wikipedia. From the US dial 011 423 and the seven-digit number, with no trunk 0. Even from Switzerland, a call to Vaduz is now an international call dialed with 00423.
Switzerland uses Central European Time, UTC+1, and summer time, UTC+2, from the last Sunday of March to the last Sunday of October - METAS. That puts it normally 6 hours ahead of New York and 9 ahead of Los Angeles. Because the US changes clocks earlier in spring and later in autumn - NIST, the gap shrinks to 5 and 8 hours for a few weeks each year.
Since 1 January 2026 for landline numbers and 1 July 2026 for mobile numbers, carriers must mark calls from abroad that display a Swiss number, and the receiving network may remove the number or block the call if it looks spoofed - OFCOM. If an app shows a Swiss caller ID while you are in the US, switch it to your real US number and call again.
Do not count on it being free. OFCOM says calls to 0800 numbers are free, except that an extra charge may apply when calling from abroad or from a call box, and 084x shared-cost numbers are priced uniformly for callers within Switzerland - OFCOM. If the company also lists a regular geographic number or an 058 office number, that is the more reliable choice from the US.
