🇨🇭 Switzerland (+41)

Switzerland Phone Number Validator & Carrier Lookup

Switzerland runs a closed nine-digit plan behind a national trunk 0 that is dropped in +41 format, and because numbers have been portable since 2000 the 07x mobile prefix no longer reveals which network carries a number. The country has three mobile operators: Swisscom, Sunrise and Salt. Fixed lines carry regional area codes such as 044 for Zürich and 022 for Geneva.

Switzerland phone number format

Switzerland numbers carry the +41 country code with a national trunk prefix of 0, dropped in E.164 format. Mobile and fixed-line ranges are distinguished by their leading digits and returned as a line_type you can filter on.

+41 78 123 45 67
Domestic form: 078 123 45 67 — the trunk prefix 0 is dropped for international format. 9 digits after +41.
Fixed line — E.164 format
+41 21 234 56 78
Domestic form: 021 234 56 78 — the trunk prefix 0 is dropped for international format. 9 digits after +41.

Switzerland mobile operators & prefixes

Each mobile prefix is allocated to a specific operator. Veriphone returns that operator from the OFCOM (Federal Office of Communications / BAKOM) numbering plan, along with line type.

Each prefix belongs to one operator — but a number can be ported. The prefix tells you the operator a number was originally allocated to. Because Switzerland allows number portability, a number can keep its prefix after switching networks, so the prefix alone doesn't guarantee the operator serving it today. A Standard lookup returns the allocated operator; add mode=current to resolve the operator serving a ported number now.
Swisscom
068–069, 072–073, 0752–0754, 0757, 0770, 0774, 0790–0798, 07500 +9 more
Largest network and former state monopoly (majority-owned by the Swiss Confederation); original allocations sit under the 075 and 079 prefixes.
Sunrise
0762–0769, 0772, 07600–07605, 07730, 07840–07842, 077310–077316
Second-largest operator on the original 076 prefix; absorbed cable operator UPC (brand retired 2022) and was spun off from Liberty Global as an independent listed company in 2024.
Salt
0780–0783, 0785–0789
Third-largest network on the original 078 prefix; formerly Orange Switzerland, rebranded Salt in 2015.

Plus 11 smaller networks (MVNOs), including Tismi, Nexphone, Relario AG (Bebbicell), BeeOne Communications, Vectone Mobile Limited (Mundio). Veriphone resolves each to its host network.

Fixed-line area codes

For landline numbers, Veriphone returns the city or region where the numbering plan resolves one. Mobile numbers are non-geographic and carry no city.

Ported numbers. Switzerland has offered number portability since 2000, so a subscriber keeps their number when switching operators. A Standard lookup returns the operator a number was originally allocated to (by its 07x prefix or fixed area code), while mode=current returns the operator actually serving a ported number today.

Questions about Switzerland number validation

Does a mobile prefix like 076, 078 or 079 tell me which operator a Swiss number belongs to?

No. Since portability arrived in 2000, a 076 number first allocated to Sunrise may now be served by Swisscom or Salt. Standard shows the original allocation; use mode=current for the operator actually serving the number.

Do I keep the leading 0 when formatting a Swiss number in E.164?

No. The national trunk prefix 0 is dropped internationally, so 044 202 xx xx becomes +41 44 202 xx xx and mobile 079 xxx xx xx becomes +41 79 xxx xx xx.

Why do some Swiss numbers have a 3-digit area code and others a 4-digit one?

The plan mixes a 3-digit code with a 7-digit subscriber number and longer codes with shorter numbers; either way the national significant number is always nine digits.

Is Sunrise the same company as UPC?

Sunrise absorbed the cable operator UPC (brand retired 2022) and became an independent listed company in 2024, so some carrier records may still label numbers 'Sunrise UPC'.
