📍 Geographic Location of Thermo
Geographic Overview
The area code 2644 is a geographic National Destination Code (NDC) assigned to the region of Thermo (also spelled Thermon or Thermο), a town and former municipality in the regional unit of Aetolia-Acarnania, in the western part of Central Greece. Thermo is situated in a mountainous area near the artificial lake of Kremasta and is historically significant as the site of the ancient Aetolian League's sanctuary. The code covers the town of Thermo and its surrounding villages, including Petalou, Aetos, and other nearby settlements. Administratively, it falls under the municipality of Agrinio (since the 2011 Kallikratis reform), but the area retains its distinct dialing code.
Dialing Format
When calling a landline in Thermo from within Greece, the national trunk prefix 0 is used, followed by the area code and the subscriber number. The full national number is 0 2644 XXXX, where XXXX is the local subscriber number (typically 4 digits). For international callers, the country code for Greece is +30, and the leading 0 is dropped. Thus, the international format becomes +30 2644 XXXX.
Example: To call a Thermo landline with subscriber number 1234, a local caller would dial 02644 1234, while an international caller would dial +30 2644 1234.
Caller Instructions
Local callers: If you are within the Thermo area code region, you may be able to dial just the subscriber number (7 digits) for local calls, but it is safer to always include the area code to avoid misrouting. For calls from other parts of Greece, dial 0 2644 followed by the subscriber number.
International callers: Dial your country's international access code (e.g., 00 from most European countries, 011 from the US/Canada), then Greece's country code 30, then the area code without the leading zero (2644), and then the subscriber number. For example, from the US, you would dial 011 30 2644 1234.
Overlay and Numbering Considerations
As of the latest ITU-T E.164 national numbering plan updates, there is no overlay code for the 2644 area. The subscriber number length is fixed at 4 digits, making the total national significant number (NSN) length 10 digits (including the leading 0). This is standard for Greek geographic codes. Calls to this code are typically charged as local or national rates depending on the caller's location and tariff plan. VoIP services may route calls to this code as well, but users should verify that their provider includes geographic numbers in their service area.
