Area Code 3117 – Eggersdorf bei Graz

Overview of Area Code 3117

Austrian area code 3117 is a geographic destination code assigned to the town of Eggersdorf bei Graz and its surrounding administrative district in the state of Styria (Steiermark). This code falls under the national numbering plan administered by the Austrian Regulatory Authority for Broadcasting and Telecommunications (RTR-GmbH), following ITU-T E.164 recommendations. The geographic area covered by 3117 includes the municipality of Eggersdorf bei Graz and nearby villages, which are part of the Graz-Umgebung district. The region benefits from its proximity to the state capital, Graz, located approximately 15 kilometers to the southwest.

Dialing Formats

For callers within Austria, the local number must be dialed in the national format: 0 3117 [subscriber number]. The leading '0' is the national trunk prefix used to access the public switched telephone network (PSTN). For example, a local call to a subscriber number 1234567 would be dialed as 0 3117 1234567.

International callers must omit the trunk prefix and dial the country code for Austria, which is +43, followed by the area code without the leading zero. Thus, the same number would be dialed as +43 3117 1234567. When writing the number in international format, it is common to use a space after the country code and after the area code: +43 3117 1234567.

Geographic Coverage and Administration

The 3117 area code serves a predominantly rural and suburban region, with Eggersdorf bei Graz being the main administrative center. The municipality includes several cadastral communities such as Eggersdorf, Purgstall, and Höf-Präbach. These areas are part of the political district of Graz-Umgebung, which surrounds the city of Graz. The region is known for its vineyards and agricultural activity, as well as its residential communities that have grown due to the spillover from the Graz metropolitan area.

As a geographic code, 3117 is used for fixed-line telephone services, including traditional PSTN and VoIP services that are registered to a physical address within the area. Subscribers may also have the option to keep their number when moving within the same geographic area, subject to local number portability rules.

Caller Instructions

For local callers within Austria, it is essential to include the trunk prefix '0' when dialing any number in the 3117 area from outside that specific area code. However, when calling from within the same area code, the trunk prefix and area code may be omitted, and only the subscriber number is dialed, depending on the local dialing plan. To avoid confusion, it is recommended to always use the full national format.

For foreign callers, ensure that you have the correct international exit code for your country (e.g., 00 from most European countries, 011 from the United States) before dialing +43. Also, note that Austrian numbers are typically 4 to 7 digits long after the area code, so the total number of digits may vary.
