Area Code 22 – Geneva

Geographic Context and Allocation

Country calling code +41 is assigned to Switzerland by the International Telecommunication Union under the E.164 standard. Within the Swiss numbering plan, the National Destination Code (NDC) 22 is a geographic area code allocated to the canton of Geneva, including the city of Geneva and its surrounding municipalities. This code is administered by the Federal Office of Communications (OFCOM) and is used for fixed-line PSTN and VoIP services that are physically located within the designated area.

Coverage Area and Administrative Jurisdiction

The +41 22 area code serves the entire canton of Geneva, which is the westernmost region of Switzerland, bordered by France. The principal city is Geneva, which hosts numerous international organizations, including the United Nations Office at Geneva and the Red Cross. Other notable municipalities covered include Carouge, Vernier, Lancy, and Meyrin. The code is also used for the CERN research facility located near Meyrin. As a geographic code, it is tied to the location of the subscriber's line, although number portability may allow retention when moving within Switzerland, subject to regulatory conditions.

Dialing Formats and Caller Instructions

For international callers, the correct format is +41 22 XXX XX XX, where the leading '0' of the national trunk prefix is omitted. For example, to call a fixed line in Geneva from abroad, one would dial +41 22 123 45 67. Within Switzerland, callers must use the national format with the trunk prefix '0': 022 XXX XX XX. Thus, the same number would be dialed as 022 123 45 67 from a Swiss phone. When dialing from a mobile phone, the international format with '+41' is also accepted. It is important to note that the area code is an integral part of the number and must always be dialed, even for local calls within Geneva, as per Swiss numbering regulations.

Overlay and Numbering Plan Considerations

Currently, there is no overlay code for the Geneva area; the 22 code is the sole geographic code for the canton. However, due to the high demand for numbers in this economically significant region, OFCOM has implemented number conservation measures. Subscribers may encounter 9-digit subscriber numbers after the area code, but the standard length is 7 digits. VoIP providers may also assign numbers with the 22 code, but the geographic association remains for emergency services routing.

Practical Guidance for Callers

For local callers within Geneva, dialing the full national number (022 XXX XX XX) is mandatory. For international callers, always replace the leading '0' with the country code +41. When saving contacts in a mobile phone, it is recommended to use the international format (+41 22 XXX XX XX) to ensure proper dialing from any location. Be aware that calls to Swiss fixed lines are typically charged at local or national rates depending on your provider, and international rates apply when calling from outside Switzerland.
