📍 Geographic Location of Chalcis
Overview of Area Code 2221
Area code 2221 is a geographic National Destination Code (NDC) within the Greek numbering plan, allocated to the city of Chalcis (Chalkida), the capital of the regional unit of Euboea (Evia) in Central Greece. This code serves the urban and suburban areas of Chalcis and its immediate surroundings, including the nearby communities of Nea Artaki, Vasiliko, and parts of the Lelantine Plain. As a geographic code, it is tied to the PSTN (Public Switched Telephone Network) and is used for fixed-line services, including traditional analog lines, ISDN, and VoIP-based fixed telephony that is registered to the area.
Dialing Formats and Usage
When calling a number within Greece, the national trunk prefix 0 is used before the area code. Thus, a local call from another part of Greece to Chalcis would be dialed as 0 2221 XXX XXXX. Internationally, callers must use the Greek country code +30, followed by the area code without the leading zero: +30 2221 XXX XXXX. For example, a typical landline number in Chalcis might be +30 2221 234567.
Local calls within the same area code (i.e., from one Chalcis number to another) can often be dialed using only the seven-digit subscriber number (XXX XXXX), without the area code, depending on the operator and the specific local dialing regulations. However, for clarity and consistency, especially when using mobile phones or VoIP services, it is recommended to always include the full national or international format.
Geographic Coverage and Administration
Chalcis is the largest city on the island of Euboea and serves as a major commercial and administrative hub. The area code 2221 is administered by the Hellenic Telecommunications and Post Commission (EETT) and is assigned to various fixed-line operators, including OTE (the incumbent), as well as alternative providers such as Vodafone Greece, Nova (formerly Wind), and other VoIP-based carriers. Number portability allows subscribers to retain their 2221 number even if they switch providers, but the number remains geographically tied to the Chalcis area for routing purposes.
Caller Instructions
- Local callers (within Greece): Dial 2221 XXX XXXX (or 0 2221 XXX XXXX from other regions).
- International callers: Dial your country's exit code, then 30 2221 XXX XXXX (omit the leading 0).
- Mobile callers: Mobile numbers in Greece do not use geographic area codes; they begin with 69X. Therefore, when calling a fixed line in Chalcis from a mobile, always include the area code.
