Area Code 2254 – Agios Efstratios

Overview of Area Code 2254

Area code 2254 is a geographic National Destination Code (NDC) assigned to the island of Agios Efstratios (also known as Ai Stratis) in the North Aegean region of Greece. This code is part of the Greek open numbering plan, where the full national significant number (NSN) consists of 10 digits, including the leading '2' of the area code. For international calls, the country calling code +30 is added before the NSN, resulting in the format +30 2254 xxxxx.

Geographic Coverage and Administration

Agios Efstratios is a small, remote island in the northern Aegean Sea, administratively part of the Lemnos regional unit. The area code 2254 serves the entire island, including its main settlement, also named Agios Efstratios. Due to the island's small population and limited telecommunications infrastructure, the subscriber numbers within this code are relatively short, typically 5 digits after the area code. The code is managed by the Hellenic Telecommunications and Post Commission (EETT) and is allocated to the incumbent operator OTE, though other providers may offer services via wholesale access.

Dialing Formats and Instructions

• Local calls (within Greece): Dial the 10-digit national number: 2254 xxxxx. For example, to call a landline on the island, you would dial 2254 12345.
• International calls (from abroad): Dial the international access prefix (00 or +), then the country code 30, followed by the area code without the leading 0, and the subscriber number: +30 2254 12345.
• Calls from Agios Efstratios to other Greek numbers: Dial the full 10-digit national number, including the leading '0' of the area code. For example, to call Athens (area code 21), you would dial 21 2345678.

Overlay and Numbering Considerations

As of the latest EETT numbering plan, there is no overlay code for Agios Efstratios; 2254 remains the sole geographic code for the island. Subscriber numbers are allocated in blocks, and due to the low population density, the risk of number exhaustion is minimal. The code is exclusively for fixed-line services, and no mobile or VoIP services are assigned under this NDC. For VoIP or mobile numbers, different prefixes apply, such as 69 for mobile networks.

Practical Information for Callers

When calling from abroad, be mindful of time zones (Greece is UTC+2 in winter, UTC+3 in summer). Also, ensure you have the correct number of digits; if you encounter a number with fewer than 5 digits after the area code, it may be an internal short code, not a public number. For emergency services, always dial 112 (European emergency number) regardless of location.
