Area Code 2923 – Pigüé, Buenos Aires

Overview of Area Code 2923

Area code 2923 is a geographic National Destination Code (NDC) within the Argentine national numbering plan, assigned to the south-western sector of Buenos Aires Province. The principal locality served is Pigüé, an administrative and commercial centre in the Tornquist Partido, together with surrounding towns and rural districts. This code is used for fixed-line (PSTN) services, and, as with all Argentine geographic codes, it is non-portable to mobile networks.

Geographic Coverage and Administrative Jurisdiction

The 2923 numbering area covers a portion of the Ventania mountain system and the adjacent Pampa Húmeda. Besides Pigüé, the code serves localities such as Saavedra, Espartillar, Puan (partially), and smaller settlements along Provincial Routes 33 and 76. Administratively, these communities fall under the municipalities of Tornquist, Saavedra, and Puan, all within the Buenos Aires Province. The region is primarily agricultural, with grain and cattle production dominating the local economy.

Dialing Formats and Caller Instructions

For international callers, the correct format is +54 2923 [local number]. The local subscriber number is seven digits long, meaning the complete international number comprises the country code (54), the area code (2923), and the seven-digit local number. For example, a Pigüé fixed-line number might be dialled as +54 2923 4XXXXXX from abroad.

Domestic callers within Argentina must dial 0 2923 [local number] when calling from a different area code. The leading 0 is the national trunk prefix, followed by the area code and the subscriber number. For calls placed from within the 2923 area itself, the local number can be dialled directly without the trunk prefix or area code.

Overlay and Numbering Considerations

As of the current numbering plan, there is no overlay code for 2923; the area maintains a single NDC. However, the Argentine communications regulator (ENACOM) has implemented number portability for fixed lines within the same geographic area, allowing subscribers to retain their numbers when changing operators. It is important to note that the 2923 code is strictly geographic; it does not apply to mobile services, which use the non-geographic 11-digit mobile prefixes (e.g., 2923 is not used for cellular).

Practical Guidance for Callers

• Local call (within 2923): Dial the 7-digit subscriber number.
• National call (from other Argentine areas): Dial 0 2923 followed by the 7-digit number.
• International call (from outside Argentina): Dial the international access prefix (e.g., 00 or +) then 54 2923 and the 7-digit number.

Businesses and residents in the region rely on this code for all fixed-line communications, including internet via ADSL or fibre, and traditional telephone services. Understanding the correct dialing format ensures seamless connectivity for both domestic and international callers.
