Area Code 2237 – Karpenisi

Overview of Area Code 2237

Area code 2237 is a geographic National Destination Code (NDC) within the Greek numbering plan, allocated to the regional unit of Evrytania in Central Greece. Its principal city is Karpenisi, the capital of Evrytania, situated on the slopes of Mount Timfristos. The code serves the town itself and the surrounding villages and settlements within the administrative boundaries of the Municipality of Karpenisi.

Geographic Coverage and Administrative Jurisdiction

The 2237 code covers a predominantly mountainous region, including communities such as Mega Chorio, Koryschades, Fourna, and Domnista. As a geographic code, it is tied to the PSTN (Public Switched Telephone Network) infrastructure of the area, although calls may be routed over IP-based networks by modern carriers. The region is part of the wider Central Greece administrative region, and the code is administered by the Hellenic Telecommunications and Post Commission (EETT).

Dialing Formats and Usage

For callers within Greece, the local dialing format is 22370 followed by the subscriber number, making the total national significant number (NSN) 10 digits when including the leading '0'. For example, a local call to a landline in Karpenisi would be dialed as 22370 12345. When calling from abroad, the international format omits the leading zero: +30 22370 12345. The plus sign represents the international access code, which varies by country (e.g., 00 in most of Europe, 011 in North America).

Overlay and Numbering Considerations

Currently, there is no overlay code for the 2237 area. Subscriber numbers within this code typically consist of five digits after the area code, resulting in a total of 10 digits for domestic calls (including the trunk prefix '0'). The code is exclusively for fixed-line services; mobile numbers in Greece use separate non-geographic prefixes starting with 69x. When dialing from a mobile phone within Greece, it is generally acceptable to dial the full national number (including the leading '0') or the international format (+30 2237...), depending on the caller's preference and carrier settings.

Caller Instructions

• Local callers (within Greece): Dial the 10-digit number starting with the trunk prefix '0': 22370 12345.
• International callers: Dial your country's exit code, then Greece's country code 30, followed by the area code without the leading zero and the subscriber number: +30 22370 12345.
• Callers from mobile phones: You can dial the number in international format (+30 2237...) to ensure proper routing, especially when roaming.
