Area Code 2299 – Markopoulo Mesogaias

Overview of Area Code +30 2299

Area code 2299 is a geographic National Destination Code (NDC) within the Greek numbering plan, assigned to the region of Markopoulo Mesogaias and its surrounding localities in the eastern part of the Attica peninsula. This area forms part of the larger Mesogeia plain, an area that has experienced significant development due to its proximity to Athens and the Athens International Airport "Eleftherios Venizelos." The code serves both the town of Markopoulo and nearby settlements, including Kalyvia Thorikou, Kouvaras, and parts of the broader Mesogeia region.

Geographically, the region falls under the administrative jurisdiction of the Attica region, specifically the regional unit of East Attica. While it is not part of the Athens metropolitan area's core, it is closely linked to the capital for economic and commuting purposes. The area is known for its mix of traditional agriculture, modern logistics, and residential communities, as well as the Markopoulo Olympic Equestrian Centre, which hosted events during the 2004 Summer Olympics.

Dialing Formats and Usage

When calling a fixed-line number in the Markopoulo area from within Greece, subscribers must dial the national trunk prefix 0 followed by the area code 2299 and the local subscriber number, which typically consists of 6 digits. This results in a total national significant number length of 10 digits (including the leading 0). For example, a local number might be formatted as:

• National format (domestic call): 0 2299 X XX XXX
• International format (from abroad): +30 2299 X XX XXX

For instance, if a subscriber's number is 345678, a caller from Athens would dial 0 2299 345678, while a caller from the United States would dial 011 30 2299 345678 (or +30 2299 345678 from a mobile phone).

It is important to note that the area code 2299 is not an overlay; it is the sole geographic code for this specific region. Subscribers within the same area code can often dial local numbers without the area code, depending on the operator's local dialing rules, but for clarity and to avoid errors, it is recommended to always use the full national number when dialing from a different area or from a mobile network.

For international callers, the Greek country code is +30, and the leading 0 of the national trunk prefix must be omitted. Therefore, the international dialing format is +30 2299 X XX XXX. This format is essential for VoIP and mobile users who need to reach fixed-line subscribers in Markopoulo.

As with all geographic numbers in Greece, calls to 2299 numbers are typically charged at standard fixed-line rates when dialed from within the country, and international rates when dialed from abroad. The area code is administered by the Hellenic Telecommunications and Post Commission (EETT) and is allocated to fixed-line operators providing PSTN and VoIP services in the region.
