Overview of Area Code 3884
Area code 3884 is a geographic National Destination Code (NDC) assigned to the city of San Salvador de Jujuy, the capital of the Jujuy Province in northwestern Argentina. This code serves the metropolitan area and surrounding localities, including Palpalá, Perico, and other nearby towns within the Greater San Salvador de Jujuy conurbation.

Dialing Formats
When calling a fixed-line number in San Salvador de Jujuy, the national subscriber number (NSN) is composed of the area code plus a 7-digit local number, resulting in a total of 10 digits (excluding the trunk prefix). The international format for Argentina is +54 3884 XXX XXXX.
- Local calls (within the same area code): Dial the 7-digit subscriber number directly. For example, to call 456-7890, simply dial 456-7890.
- National long-distance calls (from other Argentine cities): Dial the trunk prefix 0, then the area code 3884, followed by the subscriber number. Example: 0 3884 456-7890.
- International calls from abroad: Dial the international access prefix (e.g., 00 from most countries), then Argentina’s country code 54, the area code 3884 (without the leading 0), and the subscriber number. Example: +54 3884 456-7890.
Geographic Coverage and Regulatory Notes
The 3884 area code is part of the Northwest Region of Argentina’s numbering plan. It is a geographic code, meaning that the number is tied to a physical location, and calls are routed over the traditional PSTN as well as over VoIP networks that respect geographic numbering. In recent years, Argentina has implemented number portability for fixed lines, allowing users to retain their numbers when changing service providers within the same geographic area. However, the geographic nature of the code remains, and it cannot be reassigned to a different region.
For callers within Argentina, it is important to remember to include the trunk prefix 0 when dialing from outside the local area. For international callers, the leading 0 is omitted. The area code 3884 is sometimes confused with the nearby code 388 (for San Salvador de Jujuy’s older assignments), but 3884 is the current code for the city and its immediate surroundings. Always verify the correct code when placing calls to ensure proper routing.
