📍 Geographic Location of Tandil, Buenos Aires
Geographic Overview
The Argentine area code 249 is a geographic National Destination Code (NDC) assigned under the country's national numbering plan, which follows ITU-T E.164 recommendations. This code serves the southeastern region of Buenos Aires Province, with Tandil as its principal city. The coverage area includes the Partido de Tandil and extends to nearby localities such as Gardey, María Ignacia (Vela), and De la Canal, as well as parts of the surrounding rural zones. Tandil is a significant economic and tourist hub, known for its entrepreneurial activity, dairy industry, and the iconic Sierra del Tandil mountain range.
Administratively, the region falls under the jurisdiction of the Province of Buenos Aires. The code 249 is one of several geographic codes in the province, distinct from the capital's 11 area code and other interior codes like 221 (La Plata) or 223 (Mar del Plata).
Dialing Formats
For local calls within the 249 area, subscribers dial the 7-digit subscriber number directly (e.g., 442-xxxx). For national long-distance calls from other Argentine area codes, the format is 0-249-442-xxxx, where the leading '0' is the national trunk prefix. For international calls from abroad, callers must use the Argentine country code +54, followed by the area code without the trunk prefix, and the subscriber number: +54 249 442-xxxx.
Example: To call a Tandil landline from the United States, dial 011 54 249 442-xxxx (where 011 is the US exit code). From a mobile phone in Argentina, dial 0249 442-xxxx.
Regulatory and Technical Notes
Argentina's telephone numbering plan is regulated by the Ente Nacional de Comunicaciones (ENACOM). Geographic area codes are assigned to fixed-line services, but number portability allows users to retain their numbers when changing providers, though the geographic significance remains. The 249 area code does not currently have an overlay; the 7-digit local numbering capacity is sufficient for the region's demand. Calls to 249 numbers are typically routed over the PSTN or VoIP networks, and the cost depends on the caller's location and service plan.
For international callers, it is essential to omit the national trunk prefix '0' when dialing from abroad. Also, note that Argentine mobile numbers have a different structure (starting with 15 after the area code for calls within the country), but landlines under 249 follow the standard geographic format.
