Overview of Area Code +54 3868
Area code 3868 is a geographic National Destination Code (NDC) within the Argentine national numbering plan, assigned under the country calling code +54. It serves the department of Cafayate and its surrounding rural districts in the province of Salta, located in the northwest of Argentina.

Geographic Coverage and Jurisdiction
The 3868 area code covers the administrative jurisdiction of the Cafayate Department, including the city of Cafayate itself and smaller localities such as Tolombón, Las Conchas, and rural settlements along the Santa María River valley. The region is part of the Salta Province, which borders the provinces of Catamarca and Tucumán to the south. The numbering area is classified as a geographic allocation, meaning that the prefix is tied to a physical location and is used for fixed-line (PSTN) services.
Dialing Formats and Instructions
To call a fixed-line number in Cafayate from within Argentina, you must dial the national trunk prefix 0, followed by the area code 3868 and the subscriber number (which typically has 6 digits). For example, to reach a local number such as 456789, you would dial:
- National call (from other Argentine cities): 0 3868 456789
- Local call (within Cafayate): 456789 (often without the area code, depending on the operator)
From abroad, callers must use the international access prefix (e.g., 00 from many countries, or +), followed by Argentina's country code 54, the area code 3868 (without the leading 0), and the subscriber number. For example:
- International call: +54 3868 456789
Overlay and Numbering Considerations
As of the latest ITU-T E.164 updates, the 3868 area code does not have an overlay code; it remains the sole geographic NDC for the Cafayate region. However, due to the growth of mobile and VoIP services, some numbers may be routed over IP networks, but the NDC retains its geographic significance for fixed-line services. Callers should always verify the current dialing procedures with their service provider, as local call routing may vary.
