Geographic Coverage and Administration

The code 3564 is managed under the national numbering plan of Argentina, overseen by the Ente Nacional de Comunicaciones (ENACOM). It is a geographic code, meaning that the number is tied to a physical location. Calls to this code are routed to the PSTN (Public Switched Telephone Network) infrastructure serving San Francisco and its immediate surroundings. The area is part of the province of Córdoba, and the local telephone service is provided by Telecom Argentina (formerly Telefónica de Argentina) under the brand Telecom.

Overlay and Numbering Considerations

Currently, there is no overlay code for San Francisco; the area code 3564 is exclusive to this region. However, as part of the national plan, ENACOM has implemented number portability for fixed lines, allowing subscribers to retain their numbers when changing providers within the same geographic area. When dialing from a mobile phone, the same national format is used, but the call may be charged differently depending on the caller's plan.

Caller Instructions

For local callers within San Francisco, it is common to dial only the 7-digit subscriber number. However, for clarity and to avoid misdialing, many users still dial the full national format. For callers from other regions in Argentina, always include the trunk prefix 0 before the area code. For international callers, remember to replace the leading zero with the country code +54.
