📍 Geographic Location of Chios
Geographic Overview
The +30 2271 country/area code combination corresponds to the Greek national destination code (NDC) for the island of Chios, located in the North Aegean Sea. This geographic area code is assigned to the Chios regional unit, which encompasses the main island of Chios as well as the smaller inhabited islands of Psara, Antipsara, and the Oinousses group. The administrative center and largest municipality is Chios (town), often referred to as Chora, which serves as the primary hub for telecommunications, commerce, and public services on the island.
Calling Formats
When dialing a fixed-line number on Chios from within Greece, subscribers use the national trunk prefix 0 followed by the area code 2271 and the local subscriber number, which typically consists of 7 digits. Thus, a local call would be placed as: 2271 XXXXXXX. For callers from outside Greece, the international access prefix (00 or +) is used, followed by the Greek country code 30, the area code without the leading 0, and the subscriber number: +30 2271 XXXXXXX. This format complies with ITU-T E.164 recommendations.
Coverage and Overlays
The 2271 code serves the entire Chios regional unit, including the capital town and all surrounding villages and settlements. There are no overlay codes in this area; the 2271 prefix is exclusively used for geographic fixed-line services. Subscriber numbers are 7 digits long, providing a theoretical capacity of up to 10 million numbers, though actual assignments are far lower due to the island's population. The numbering plan is managed by the Hellenic Telecommunications and Post Commission (EETT), and local loop unbundling allows alternative operators to provide services using the same code.
Dialing Instructions
For local callers within Chios, it is possible to dial the subscriber number directly without the area code in some cases, but for clarity and to avoid misdialing, it is recommended to always include the area code. For international callers, the plus sign (+) is used in mobile phones, followed by the country code and area code. For example, to call a business in Chios town from the United States, one would dial: 011 30 2271 XXXXXXX. From the United Kingdom, it would be: 00 30 2271 XXXXXXX.
Practical Considerations
When calling from a mobile phone within Greece, the area code is mandatory even for local calls, as mobile networks require the full national number. For travelers, it is important to note that calls to Greek landlines are typically charged at higher rates than calls to mobiles, depending on the operator. Emergency services are reached via 112 (European emergency number) or 100 (police), 166 (ambulance), and 199 (fire brigade), which are free from any phone. For any number portability or service inquiries, users should contact their service provider or consult the EETT website.
