Area Code 2274 – Psara, Chios

Overview of Area Code 2274

Area code 2274 is a geographic National Destination Code (NDC) within the Greek national numbering plan, allocated under the country calling code +30. It serves the island of Psara, a small but historically significant island in the North Aegean Sea, and is administered as part of the regional unit of Chios. The code is used for fixed-line telephone services (PSTN) and is assigned to subscribers physically located within the local exchange area of Psara.

Geographic Coverage and Administrative Jurisdiction

The 2274 code covers the entire island of Psara, including its main settlement (also named Psara) and the surrounding islets that form the municipal unit. Psara is part of the Chios regional unit, which is in the North Aegean administrative region of Greece. Although the code is associated with Psara, it is important to note that the neighboring island of Chios uses different area codes (2271 for Chios town and 2272 for the rest of Chios), so 2274 is exclusively for Psara's fixed-line network.

Dialing Formats and Instructions

For callers within Greece, the local dialing format is the national significant number (NSN), which includes the area code followed by the subscriber number. For Psara, the NSN is 2274 0xxxx (where x represents digits), making the total length 10 digits. To call a Psara number from another Greek city, dial: 2274 0xxxx. For international callers, the format is +30 2274 0xxxx (or 0030 2274 0xxxx from countries using the international prefix 00). When dialing from abroad, the leading zero of the area code is omitted, as per E.164 standards.

Overlay and Numbering Considerations

As of the latest ITU-T and Greek regulatory updates, there is no overlay code for the 2274 area. The numbering capacity is sufficient for the small population of Psara. Subscriber numbers within this code typically have a length of 5 digits after the area code, but the total NSN length is always 10 digits. Callers should always include the area code even for local calls within Psara, as Greece uses closed dialing plan, meaning the full 10-digit number must be dialed for all calls, including on-net calls.

Practical Information for Callers

For local callers within Psara, dialing the full NSN (2274 0xxxx) is mandatory. For foreign callers, ensure you use the international access prefix of your country (e.g., 011 from the US/Canada, 00 from most European countries) followed by 30 and the NSN without the leading zero. Example: to call a Psara number 01234, dial +30 2274 01234 from a mobile phone. Note that calls to this geographic code are typically charged at standard national rates when dialed from within Greece, and international rates when dialed from abroad.
