Area Code 3435 – Nogoyá, Entre Ríos

Overview of Area Code 3435

Area code 3435 is a geographic National Destination Code (NDC) assigned to the city of Nogoyá and its surrounding localities in the province of Entre Ríos, Argentina. This code is part of the national numbering plan administered by the Ente Nacional de Comunicaciones (ENACOM), following the ITU-T E.164 recommendation. The region is situated in the central-south of Entre Ríos, along the banks of the Gualeguay River, and serves as an important agricultural and commercial hub.

Geographic Coverage and Jurisdiction

The 3435 area code covers the Nogoyá Department, which includes the administrative seat of Nogoyá and smaller towns such as Lucas González, Aranguren, and Hernández. These localities fall under the provincial jurisdiction of Entre Ríos, and the area code is used for all fixed-line telephone services within this geographic boundary. The region is part of the Argentine PSTN (Public Switched Telephone Network), and numbers are allocated to local exchange areas, with each subscriber line assigned a unique local number typically of 6 to 7 digits.

Dialing Formats and Instructions

To call a fixed-line number in Nogoyá from within Argentina, you must dial the trunk prefix 0, followed by the area code 3435 and the subscriber number. For example, if the local number is 456789, the national dialing format is:

• From a landline in Argentina: 0 3435 456789
• From a mobile phone in Argentina: 0 3435 456789 (same as landline)

For international callers, the Argentine country code is +54. You must drop the trunk prefix 0 and dial the area code without the leading zero. The international format is:

• From abroad: +54 3435 456789

Note that when calling from a mobile phone within Argentina, the same national format applies, as there is no separate mobile access code for fixed-line calls. However, if you are calling a mobile number in Nogoyá, you would use the mobile-specific area code 3435 as well, but the subscriber number length may differ (usually 8 digits for mobile). Always verify the complete number with the recipient.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 3435 area. The area code is exclusively used for geographic numbers in the Nogoyá region. However, as with all Argentine fixed-line numbers, number portability is available, allowing subscribers to retain their numbers when switching between fixed-line operators. This does not affect the geographic significance of the area code; the number remains associated with the original location for routing purposes.

Caller Instructions

For local callers within the same area code, it is common to dial only the local subscriber number (without the area code) for calls within the same exchange. For example, if you are in Nogoyá and calling another local line, you may dial just 456789. However, for calls from other area codes or from mobile networks, the full national format (0 3435 + number) is required. International callers must always use the +54 country code and drop the leading zero of the area code.
