Dialing Formats

When calling a fixed-line number in Luján from within Argentina, the standard national dialing format is:

• National (domestic) call: Dial 0 (trunk prefix) followed by the area code 2323 and the subscriber number (6 to 7 digits). For example, to reach a local number 456-7890, you would dial 0 2323 456-7890.
• International call from outside Argentina: Dial the international access code (e.g., 00 from most countries, or + from mobile phones) followed by Argentina's country code 54, then the area code 2323 (without the leading 0), and the subscriber number. For instance, from the United States, you would dial 011 54 2323 456-7890; from a mobile phone, +54 2323 456-7890.

Note that the trunk prefix 0 is used only for domestic calls within Argentina. When dialing from abroad, the 0 is omitted.

Geographic Coverage and Administration

Area code 2323 is part of the Argentine national numbering plan, which is administered by the Ente Nacional de Comunicaciones (ENACOM). The code is classified as a geographic code, meaning that the number is tied to a physical location. Calls to 2323 numbers are routed to the Luján exchange, and the tariff for calls to this area is based on the distance from the caller's location, as per traditional PSTN regulations.

Luján is situated within the Buenos Aires Province, which is part of the larger metropolitan region of Buenos Aires. However, it is not part of the immediate Greater Buenos Aires urban agglomeration, and thus retains its own distinct area code. The city is a key transportation hub, with major highways and railway lines connecting it to the capital and other provinces.

Caller Instructions

• Local callers (within Luján): For calls within the same area code, you may typically dial only the subscriber number (7 digits) without the area code or trunk prefix. However, due to number portability and multi-line exchanges, it is always safe to dial the full national format.
• Domestic callers from other Argentine cities: Always include the trunk prefix 0 and the area code 2323.
• International callers: Use the +54 2323 format, ensuring you drop the leading 0.

As with all geographic numbers in Argentina, the subscriber number length may vary, but it is typically 6 to 7 digits. Always verify the exact number with the recipient to avoid dialing errors.
