Area Code 484 – Santa Catarina

Overview of Area Code 484 (Brazil)

Area code 484 is a geographic National Destination Code (NDC) assigned to the state of Santa Catarina in southern Brazil. It serves a specific region within the state, primarily covering the municipalities of Chapecó, Xanxerê, Concórdia, and surrounding areas in the western part of Santa Catarina. This area is known for its agricultural economy, agro-industries, and growing urban centers.

Geographic Coverage and Administrative Jurisdiction

The 484 code is part of the Brazilian national numbering plan administered by ANATEL (Agência Nacional de Telecomunicações). It covers a contiguous region in the west of Santa Catarina, which is subdivided into several local calling areas. The principal city is Chapecó, a major regional hub, followed by other significant municipalities such as Xanxerê, Concórdia, and São Miguel do Oeste. The region is bordered by the state of Rio Grande do Sul to the south and Argentina to the west.

Dialing Formats

For local calls within the same area code (and same local calling area), subscribers typically dial only the 8-digit local number. However, for calls between different local areas within the 484 region, the full 10-digit number (area code + local number) is required. For international calls to this region, callers must dial the international prefix (e.g., 00 from many countries, or +), followed by Brazil's country code 55, then the area code 484, and the 8-digit local subscriber number. For example, a call to a landline in Chapecó would be dialed as +55 48 4XXX-XXXX (note: the local number begins with a '4' in many cases, but not always).

Overlay and Numbering Considerations

As of the latest ANATEL updates, there is no overlay code for 484; it is the sole area code for this region. However, due to increasing demand, some areas may have adopted additional digit requirements for mobile numbers. It is essential to always include the area code when dialing from a mobile phone, even for local calls, as Brazilian mobile numbers require the full 10-digit format (area code + 9-digit mobile number) for all calls.

Caller Instructions

For local callers: When calling within the same municipality, you may dial just the 8-digit number. For calls to other municipalities within the 484 region, dial the area code first, then the number. For international callers: Always use the international format: +55 484 XXXXXXXX. Ensure you replace the leading zero of the local number if present (Brazilian numbers do not have a trunk prefix in international format).

This area code is vital for businesses and individuals connecting with the thriving western Santa Catarina economy, which includes major agribusiness companies and a strong services sector.
