Area Code 482 – Santa Catarina

Overview of Area Code 482

Area code 482 is a geographic National Destination Code (NDC) assigned to the southern Brazilian state of Santa Catarina. It serves a specific region within the state, distinct from other Santa Catarina codes such as 47, 48, and 49. The 482 code is part of the Brazilian telephone numbering plan, which follows the ITU-T E.164 standard. The full international dialing format for numbers in this region is +55 482 XXXX-XXXX, where +55 is Brazil's country calling code.

Geographic Coverage and Jurisdiction

The 482 area code covers a cluster of municipalities in the southern and western parts of Santa Catarina. Key cities served include Araranguá, Criciúma, Forquilhinha, Içara, Nova Veneza, and Orleans, among others. This region is known for its coal mining history and growing industrial and agribusiness sectors. The administrative jurisdiction falls under the Brazilian National Telecommunications Agency (ANATEL), which oversees numbering allocation and local call regulations.

Dialing Formats and Caller Instructions

For local calls within the 482 area code, callers must dial the 8-digit subscriber number (e.g., 3456-7890). For calls from other Brazilian area codes, dial 0 + operator code + 482 + subscriber number (e.g., 0 15 482 3456-7890). International callers should dial +55 482 3456-7890 (or the exit code of their country, such as 011 from the US, followed by 55 482...).

Numbering Structure and Overlays

Brazilian geographic numbers are typically 8 digits long, but with the growing demand, ANATEL has introduced 9-digit numbers for mobile services. However, for fixed lines in the 482 region, the subscriber number remains 8 digits. There are no current overlay plans for 482; the code is used exclusively for fixed-line services, while mobile numbers in the same geographic area use the same area code but have 9-digit numbers starting with 9 (e.g., +55 48 9XXXX-XXXX). It is important to note that 482 is not an overlay of 48; rather, it is a separate NDC for a different set of municipalities.

Regulatory and Technical Notes

All fixed-line numbers in Brazil are assigned to specific concessionaires, and local calls are subject to national tariff regulations. Since 2015, ANATEL has required that all fixed-line numbers be portable within the same area code, allowing users to switch providers while retaining their number. For VoIP services, users may be assigned a 482 number if they have a physical presence in the region, but the service is location-independent for the end user.

When dialing from abroad, ensure you have the correct country code (+55) and omit any leading zero that might appear in local dialing instructions. For example, a number written as (482) 3456-7890 in Brazil should be dialed as +55 482 3456-7890 internationally.
