Area Code 7745 – Lochen

Overview of Area Code 7745

Austria's area code 7745 is a geographic National Destination Code (NDC) assigned to the municipality of Lochen am See, located in the district of Braunau am Inn in the state of Upper Austria (Oberösterreich). This code is part of the Austrian public switched telephone network (PSTN) and is used for fixed-line services within this specific locality. The region is situated near the Salzburg border and the scenic Lake Lochen (Lochsee), making it a notable rural and tourist area.

Geographic Coverage and Jurisdiction

The 7745 prefix serves Lochen am See and its immediate surroundings, including nearby villages and hamlets that fall under the same local exchange area. The administrative responsibility lies with the Austrian Regulatory Authority for Broadcasting and Telecommunications (RTR-GmbH), which oversees numbering assignments in accordance with ITU-T E.164 recommendations. The code is geographically allocated, meaning that the tariff and routing are based on the physical location of the line, not on the service provider.

Dialing Formats and Instructions

For callers within Austria, the local dialing format requires the national trunk prefix 0 followed by the area code and the subscriber number. For example, to call a fixed line in Lochen, you would dial: 0 7745 XXXXX (where XXXXX is the local subscriber number, typically 4 to 6 digits). Internationally, callers must use the Austrian country code +43, drop the leading zero, and dial: +43 7745 XXXXX. For instance, a complete international number might appear as +43 7745 12345.

Overlay and Numbering Considerations

As of the latest numbering plan updates, there is no overlay code for the 7745 area. The area code is unique to this region, and all fixed-line numbers within Lochen share this prefix. Subscriber numbers are not portable to other geographic areas, but fixed-line number portability is available among different providers within the same geographic area, allowing users to retain their numbers when switching operators.

Caller Guidance

Local callers within Lochen can often dial the subscriber number without the area code if they are in the same local calling area, but it is always safe to use the full national format. For foreign callers, ensure you have the correct country code and omit the leading zero. Be aware that calls to Austrian fixed lines are typically charged at standard landline rates, which may vary depending on your telecom provider and any international calling plans.
