Area Code 2983 – Tres Arroyos, Buenos Aires

Overview of Area Code 2983

Area code 2983 is a geographic National Destination Code (NDC) assigned to the city of Tres Arroyos and its surrounding administrative district in the southern part of Buenos Aires Province, Argentina. This region is part of the country's interior, located approximately 500 km south of the Autonomous City of Buenos Aires. The code serves a mix of urban and rural areas, including the towns of Claromecó, Orense, and San Francisco de Bellocq, which are popular for their Atlantic coast beaches and agricultural activity.

Dialing Formats

To call a fixed-line number in Tres Arroyos from within Argentina, you must dial the national trunk prefix 0, followed by the area code 2983 and the subscriber number. For example, to reach a local number such as 456-7890, you would dial:

• 0 2983 456-7890 (domestic call from another Argentine city)

From abroad, callers must use the international access code (e.g., 00 from most countries, or + from mobile networks), followed by Argentina's country code 54, the area code without the leading zero, and the subscriber number:

• +54 2983 456-7890 (international call)

Local calls within the same area code may be dialed using only the 7-digit subscriber number, depending on the operator's configuration. However, due to the national numbering plan, it is always safe to include the area code even for local calls.

Geographic Coverage and Administration

The 2983 area code is managed under the Argentine national numbering plan, overseen by the Ente Nacional de Comunicaciones (ENACOM). It covers the Tres Arroyos Partido, which is an administrative subdivision of Buenos Aires Province. The principal city, Tres Arroyos, serves as the commercial and administrative hub for the region, with economic activities centered on agriculture, livestock, and tourism. The area code is exclusively for fixed-line services (PSTN and fixed wireless), and it is not used for mobile numbers, which are non-geographic and typically begin with 15 or 11 after the country code.

Overlay and Numbering Considerations

As of the latest ENACOM regulations, there is no overlay code for 2983; the area code remains the sole NDC for this geographic region. Subscriber numbers are 7 digits long, and the total length of a national significant number (NSN) is 10 digits (including the area code but excluding the trunk prefix). When dialing from abroad, the NSN is 10 digits, and the leading '0' is omitted. This consistency simplifies international dialing and reduces the risk of misdialing.

Caller Instructions

For local callers within Tres Arroyos, dialing the 7-digit number directly may work, but it is recommended to use the full national format (0-2983-XXXXXXX) to ensure connectivity across all carriers. For callers from other Argentine provinces, always include the trunk prefix '0' before the area code. For international callers, replace the '0' with the '+' sign and the country code 54, then dial the area code and subscriber number. Remember that Argentine fixed-line numbers do not require a '15' prefix for calls from abroad; that prefix is only used for mobile numbers.
