Area Code 487 – Santa Catarina

Overview of Area Code 487

Area code 487 is a geographic National Destination Code (NDC) within the Brazilian national numbering plan, assigned to the northern and northeastern regions of the state of Santa Catarina. This area code serves a mix of urban and rural municipalities, with the principal cities including Joinville, Mafra, São Bento do Sul, Rio Negrinho, and Canoinhas. The region is characterized by strong industrial activity, particularly in Joinville, which is a major manufacturing hub for metalworking, plastics, and software development.

Geographic Coverage and Jurisdiction

The 487 code covers the microregions of Joinville, Canoinhas, and São Bento do Sul, under the administrative jurisdiction of the Brazilian telecommunications regulator, ANATEL. It is part of the state's numbering plan, which is subdivided into several area codes to optimize call routing and numbering resource allocation. The region is served by a mix of incumbent operators (such as Oi, now part of Vivo) and competitors (Claro, TIM, and regional providers).

Dialing Formats and Procedures

For local calls within the same area code, callers must dial the 8-digit subscriber number preceded by the area code, even for calls within the same city. For example, to call a fixed line in Joinville, you would dial 0 + 487 + 8-digit number (if using a carrier selection code) or simply 487 + 8-digit number from a mobile phone. For international callers, the format is +55 487 XXXX-XXXX (or +55 48 7XXX-XXXX, depending on the number length). Note that since 2016, Brazilian fixed-line numbers have been standardized to 8 digits, and the area code is mandatory for all calls, including local ones.

Overlays and Numbering Changes

Unlike some Brazilian area codes that have experienced overlays (e.g., 11 in São Paulo), area code 487 has not undergone an overlay. However, ANATEL has been migrating fixed-line services to IP-based networks, which may affect routing but not the dialing format. Users should be aware that mobile numbers in this region start with the digit '9' and are 9 digits long (e.g., +55 48 9XXXX-XXXX), while fixed lines are 8 digits.

Caller Instructions

For callers within Brazil, dialing from a mobile phone to a fixed line in the 487 area requires pressing the area code followed by the number. For example, from São Paulo, you would dial 0487 + 8-digit number (the leading '0' is used for long-distance calls). For international callers, always use the country code +55, then the area code 487, and the subscriber number. Remember to drop any leading '0' when calling from abroad.

This area code is an integral part of Brazil's telecommunications infrastructure, ensuring efficient communication for residents and businesses in this economically vibrant region.
