Geographic Overview of Swiss Area Code +41 55
Area code +41 55 is a geographic National Destination Code (NDC) assigned to the Rapperswil-Jona region and its surrounding areas in the canton of St. Gallen, Switzerland.

The region is known for its historic old town, the Rapperswil Castle, and the Seedamm causeway connecting to Pfäffikon.
Dialing Formats and Number Structure
Swiss geographic numbers are variable in length, typically consisting of the NDC (starting with 0 in national format) plus a subscriber number of 7 to 9 digits. For area code 55, subscriber numbers are 7 digits long, making the complete national number 055 XXX XX XX. When dialing internationally, the leading zero is dropped, and the country code +41 is used, resulting in +41 55 XXX XX XX.
For example, a local call to a business in Rapperswil would be dialed as 055 123 45 67 from within Switzerland. From abroad, the same number is dialed as +41 55 123 45 67.
Caller Instructions
If you are calling from within Switzerland to a number in the 055 area code, you must always use the national trunk prefix 0 before the area code, even if you are calling from a neighboring area code. For international callers, replace the leading 0 with the Swiss country code +41. No additional access codes are required for calls from mobile phones, but be aware that international roaming charges may apply if you are using a foreign SIM card.
Overlay and Numbering Plan Considerations
Currently, there is no overlay code for the Rapperswil region; 055 is the sole geographic area code for this area. However, due to the liberalization of the Swiss telecom market, subscribers in this region may have ported their numbers to alternative providers, including VoIP or cable operators. In such cases, the geographic significance of the number may not strictly reflect the physical location of the line, but the number remains associated with the Rapperswil area for routing and administrative purposes.
For businesses, having a local 055 number can enhance trust and local presence. When dialing from abroad, always use the full international format to ensure proper routing through the Swiss PSTN.
