📍 Geographic Location of Pilar, Buenos Aires
Overview of Area Code 2304
Area code 2304 is a geographic National Destination Code (NDC) assigned to the city of Pilar and its surrounding localities in the province of Buenos Aires, Argentina. Pilar is a rapidly growing urban center located approximately 60 kilometers northwest of the Autonomous City of Buenos Aires, and it forms part of the Greater Buenos Aires metropolitan area. The code serves a mix of residential, commercial, and industrial zones, including the renowned Pilar Industrial Park and several gated communities.
Geographic Coverage and Administrative Jurisdiction
The 2304 area code covers the administrative jurisdiction of the Pilar Partido, which includes the city of Pilar itself as well as smaller towns and rural areas such as Manuel Alberti, Villa Rosa, and Lagomarsino. It is important to note that this code is exclusively for fixed-line (PSTN) services; mobile numbers in Argentina use the non-geographic prefix 9 followed by the area code, but for international dialing, the 9 is omitted after the country code.
Dialing Formats and Instructions
For callers within Argentina, local calls within the same area code require dialing only the 7-digit subscriber number. For calls from other Argentine cities, dial 0 followed by the area code 2304 and the 7-digit local number. For example, to call a Pilar landline from Buenos Aires City, you would dial: 0 2304 123-4567.
For international callers, the correct format is: +54 2304 123-4567, where +54 is Argentina's country calling code. Note that the leading trunk prefix '0' is not used when calling from abroad.
Overlay and Numbering Plan Considerations
As of the current numbering plan, area code 2304 does not have an overlay code; it is the sole NDC for the Pilar region. However, due to the area's rapid expansion, the National Communications Entity (ENACOM) periodically reviews numbering resources. Subscribers should be aware that number portability is available for fixed lines, allowing users to retain their number when changing providers within the same geographic area.
Practical Tips for Callers
When calling from a mobile phone in Argentina, you may need to include the area code even for local calls, depending on your carrier. For international callers, always verify the local number length (7 digits) and avoid adding any extra digits. For fax or data services, the same dialing rules apply.
