📍 Geographic Location of Deán Funes, Córdoba
Overview of Area Code 3521
Area code 3521 is a geographic National Destination Code (NDC) within the Argentine national numbering plan, governed by the Ente Nacional de Comunicaciones (ENACOM) under ITU-T E.164 recommendations. It serves the city of Deán Funes and its surrounding administrative district in the northern region of Córdoba Province. Deán Funes is the head town of the Ischilín Department, located approximately 120 km northwest of the provincial capital, Córdoba City. The code covers a predominantly rural and semi-urban area, including localities such as Quilino, Villa Quilino, and smaller settlements within the department's jurisdiction.
Geographic Coverage and Jurisdiction
The 3521 numbering area is part of the Argentine National Numbering Plan, which assigns geographic codes to specific provinces and their internal administrative divisions. Unlike mobile or non-geographic services, this code is tied to fixed-line infrastructure, primarily operated by Telecom Argentina (under the personal brand) and other licensed local carriers. The region's PSTN network is fully digital, supporting both traditional analog lines and VoIP-based fixed services that retain geographic numbering.
Dialing Formats and Caller Instructions
For callers within Argentina, the national dialing format requires the use of a trunk prefix '0' followed by the area code and the subscriber number. The complete national significant number (NSN) for a fixed line in Deán Funes is 11 digits (excluding the trunk prefix). The structure is: 0 + 3521 + XXXXXX (where XXXXXX is the 6-digit local subscriber number).
Example (domestic call):
To call a fixed line in Deán Funes from Buenos Aires, dial: 0 3521 456789.
For international callers, the Argentine country code is +54. The trunk prefix '0' is omitted, and the area code is dialed without the leading '0'. The international format is: +54 3521 XXXXXX.
Example (international call):
From the United States, dial: 011 54 3521 456789 (or +54 3521 456789 from a mobile phone).
Overlay and Numbering Considerations
As of the latest ENACOM updates, there is no overlay code in the 3521 area; the code remains exclusive to the Deán Funes region. However, ENACOM has implemented a national plan to unify the dialing format for fixed lines, requiring the use of the 0 prefix for all domestic calls, even within the same area code. Local calls within Deán Funes can be dialed using only the 6-digit subscriber number, but for clarity and future-proofing, the full national format is recommended.
Practical Information for Businesses and Residents
Businesses operating in the region should display their numbers in international format on websites and marketing materials to facilitate global contact. For foreign callers, it is essential to note that Argentine fixed-line numbers are not mobile and cannot receive SMS. Additionally, when calling from abroad, ensure that you have the correct exit code for your country (e.g., 011 from North America, 00 from most European countries) before dialing +54 3521.
