+41 75, 76, 77, 78 and 79: Swiss mobile numbers

A number starting +41 75, 76, 77, 78 or 79 (075-079 inside Switzerland) is a Swiss mobile number. OFCOM (BAKOM) designates these codes for mobile services and assigns them in blocks of 10,000 numbers to providers. Mobile numbers have been portable between Swiss providers since 1 March 2000, so the prefix doesn't tell you the caller's current operator.

What these numbers look like

From abroad: +41 7X XXX XX XX
Inside Switzerland: 07X XXX XX XX

Nine digits after +41: a 2-digit mobile code (75-79), a 3-digit block identifier and 4 digits. 074 is paging, not mobile phones.

Who uses +41 75 to 79 numbers?

OFCOM's numbering plan (SR 784.101.113/2.2, edition 8, in force since 1 March 2024) designates 075, 076, 077, 078 and 079 (also 068, 069, 072 and 073) for mobile telecommunications services, with 074 reserved for paging. Providers receive blocks of 10,000 numbers ('0yz abc xxxx'). 079 is Swisscom's original mobile code. Swisscom applied to OFCOM for 075 blocks in 2013 because its 079 blocks were running out, and in 2015 it began giving 075 numbers to new prepaid customers.

Prefix	Operator	Note
079, 075	Swisscom	079 since the start of digital mobile service; 075 added from 2013 as 079 blocks ran out (Swisscom)

Who is calling you from a +41 75 to 79 number?

Usually a private person or a business using a Swiss mobile. Since numbers move freely between Swisscom, Sunrise, Salt and smaller providers, the prefix is only a historical hint. Calls from abroad that show a Swiss number are now marked by transit providers. Under OFCOM's caller identification rules (edition 4 of SR 784.101.113/1.7), this has applied to fixed-line numbers since 1 January 2026 and to mobile numbers since 1 July 2026. If marking isn't possible, the caller number is removed, and the receiving provider may remove the number or block the call.

Scams seen with +41 75 to 79 numbers

Spoofed Swiss numbers on calls from abroad. Cantonal police and Swiss Crime Prevention warn that scammers abroad fake Swiss caller IDs, even the police emergency number 117, to pose as police, banks or companies. Police say they never call from 117.
Fake police officers ('falsche Polizisten') pressuring people to hand over cash or valuables. Swiss police say real officers never ask you to hand over or deposit money.

What to do about a call from +41 75 to 79
