Overview of Area Code 351
Area code 351 is the National Destination Code (NDC) for the city of Córdoba, the capital of the homonymous province in central Argentina. Geographically, it covers the metropolitan area of Córdoba, including the city proper and its surrounding urban and suburban zones. As a geographic code, it is tied to the PSTN (Public Switched Telephone Network) and is used for fixed-line services, although some VoIP and mobile services may also be allocated within this range for local presence.
Dialing Formats
For local calls within the Córdoba metropolitan area, the subscriber number is dialed as an 8-digit number, preceded by the area code only when calling from outside the local area. The full national dialing format is:
- National (from within Argentina): 0-351-XXXX-XXXX
- International (from abroad): +54-351-XXXX-XXXX
Here, XXXX-XXXX represents the 8-digit local subscriber number. For example, a local number might be 351-452-1234; to call it from Buenos Aires, you would dial 0-351-452-1234, and from another country, +54-351-452-1234.
Geographic Coverage and Administration
The 351 code is administered by the Argentine communications regulator (ENACOM) and is assigned to the Córdoba metropolitan region. It serves the city of Córdoba, which is the second most populous city in Argentina, and includes important districts such as Nueva Córdoba, Cerro de las Rosas, and Güemes. The code also covers nearby localities that are part of the Greater Córdoba conurbation, such as La Calera, Villa Allende, and Malvinas Argentinas.
Overlays and Numbering
Currently, there is no overlay code for 351; the area code remains exclusive to the region. However, due to increasing demand, ENACOM has implemented number pooling and conservation measures. All fixed-line numbers in this area are 8 digits long, and the total number length (including the area code) is 11 digits for national dialing (excluding the trunk prefix 0).
Caller Instructions
For callers within Argentina, always include the trunk prefix 0 before the area code when dialing from a different region. For international callers, replace the trunk prefix with the Argentine country code +54 and omit the leading 0. For example, to call a Córdoba number from the United States, dial 011-54-351-XXXX-XXXX.
When dialing from a mobile phone within Argentina, the same national format applies. It is important to note that for calls to fixed lines, the caller may be charged according to their service provider's rates, which typically differentiate between local, national, and international destinations.
