📍 Geographic Location of Coronel Dorrego, Buenos Aires
Geographic Overview
The Argentine national destination code 2921 is a geographic area code assigned under the national numbering plan administered by the Ente Nacional de Comunicaciones (ENACOM). It serves the southeastern region of Buenos Aires Province, with its principal locality being Coronel Dorrego. The code covers the administrative partido of Coronel Dorrego and its surrounding rural districts, including smaller towns such as Monte Hermoso (though some mobile services in the area may use non-geographic codes) and several agricultural communities. The region is part of the Pampas, characterized by farming and tourism along the Atlantic coast.
Dialing Formats
For callers within Argentina, the national trunk prefix 0 is used before the area code, followed by the subscriber number. The local subscriber number in this area typically consists of 7 digits, making the complete national significant number (NSN) 10 digits (0 + 2921 + 7 digits). For example, a local number 456-7890 would be dialed as 0-2921-456-7890 from anywhere in Argentina.
For international callers, the Argentine country code +54 is used, and the leading trunk prefix '0' is omitted. Thus, the same number is dialed as +54-2921-456-7890 from abroad. When calling within the same area code, it is possible to dial only the 7-digit subscriber number in many cases, but for clarity and to avoid issues with overlays, it is recommended to use the full national format.
Caller Instructions
- Local callers (within 2921): Dial the 7-digit subscriber number directly (e.g., 456-7890).
- National callers (outside 2921): Dial 0-2921-456-7890.
- International callers: Dial +54-2921-456-7890 (or the appropriate international prefix from your country, e.g., 011 from the US, 00 from most European countries).
Administrative and Regulatory Notes
As a geographic code, 2921 is tied to the physical location of the fixed-line service. It is used for traditional PSTN and VoIP services that are registered to an address within the coverage area. Number portability is available in Argentina, allowing users to retain their numbers when changing providers, but geographic numbers generally remain associated with the original rate center. No overlay codes are currently planned for this area, so the 7-digit local dialing remains standard.
