The service area includes Miramar itself, along with nearby localities such as Mar del Sud, Centinela del Mar, and rural zones within the General Alvarado Partido.
Geographic Coverage and Jurisdiction
Administratively, the 2291 area code falls under the jurisdiction of the General Alvarado district, with Miramar serving as the principal urban center. The region is situated approximately 450 kilometers south of Buenos Aires city, along the Atlantic coastline. The code covers both urban and rural subscribers, including fixed-line PSTN and VoIP services that are geolocated to this area.

For callers within Argentina, the national trunk prefix 0 is used before the area code. The complete national dialing format is:

Local calls within the 2291 area (i.e., between Miramar and nearby towns) are dialed using only the six-digit subscriber number, without the area code. For example, to call a local number, simply dial XXXXXX.
Numbering and Overlay Considerations
Currently, there is no overlay code for the 2291 area; it is a standalone NDC. Subscriber numbers in this area are six digits long, resulting in a total national significant number (NSN) length of ten digits (including the area code). No recent changes to the numbering plan have been announced for this region, but users should always verify the current dialing procedures with their service provider, especially when using VoIP or mobile services.
Caller Instructions
For local callers within Miramar: dial the six-digit number directly. For callers from other Argentine provinces: dial 0-2291 followed by the six-digit number. For international callers: dial your country's exit code, then 54, then 2291, and the six-digit number. Remember to omit the initial '0' of the national prefix when calling from abroad.
