Area Code 2691 – Aigio

Geographic Coverage and Administrative Context

The Greek country calling code +30 is paired with the geographic area code 2691 to reach subscribers with fixed-line telephone numbers in the regional unit of Aigialeia, located in the northern Peloponnese. This numbering area primarily serves the coastal town of Aigio (also spelled Aegio or Aigion), which is the capital of the Aigialeia municipality. The 2691 area code also covers nearby settlements and communities within the municipal boundaries, including Diakopto, Akrata, and the broader mountainous and coastal zones of the Corinthian Gulf. Administratively, this region falls under the jurisdiction of the Decentralized Administration of Peloponnese, Western Greece and the Ionian Islands. The geographic allocation of 2691 follows the national numbering plan administered by the Hellenic Telecommunications and Post Commission (EETT), ensuring that numbers are tied to the PSTN exchange infrastructure in that specific locality.

Dialing Formats and Caller Instructions

For callers within Greece, the full national dialing format is 2691 0XXXX (where X represents the subscriber's local number digits). When dialing from a landline or mobile phone inside Greece, you must include the trunk prefix 0 before the area code: 0 2691 XXXXX. For international callers, the leading zero is omitted, and the number is dialed as +30 2691 XXXXX. For example, a local number in Aigio might be listed as 2691 23456; from abroad, you would dial +30 2691 23456. It is important to note that Greek fixed-line numbers typically have 10 digits in total when the leading trunk prefix is included (e.g., 0 2691 XXXXXX), but the subscriber number length within the 2691 area can vary. Always verify the exact number of digits with the person or business you are contacting.

Overlay and Numbering Considerations

As of the current numbering plan, the 2691 area code does not have an overlay code; it is the sole geographic code for the Aigio region. However, subscribers in this area may have migrated to VoIP or alternative fixed-line services, but the geographic number remains associated with the physical location for regulatory and emergency services purposes. When dialing from a mobile phone, you must always include the area code, even if the call is local, because Greek mobile networks require full national numbering. For emergency services (112), the call is routed based on the caller's location, not the area code, so dialing 112 from a fixed line in Aigio will connect to the appropriate local emergency dispatch.

Practical Usage for Businesses and Residents

Businesses operating in Aigio often display their numbers in international format (+30 2691 ...) to facilitate contact from overseas clients and partners. For callers outside Greece, it is essential to use the +30 prefix followed by the area code without the trunk zero. If you are traveling in the region and need to call a local number, using the national format with the leading 0 is required. Understanding the correct dialing procedure ensures efficient communication with this historic coastal town, known for its agricultural production and proximity to the Rio-Antirrio bridge.
