BR — Brazil

Brazil is the largest country in South America and the fifth-largest in the world, home to over 210 million people and the Amazon rainforest. Brasília, the planned capital built in the 1960s, is the seat of government, while São Paulo and Rio de Janeiro are the economic and cultural powerhouses. The Brazilian Real (BRL) uses the R$ symbol and is one of the most traded emerging market currencies. For developers, the BR country code maps to the pt-BR locale — Brazilian Portuguese is the most important Portuguese locale by far, with different spelling, vocabulary, and formatting conventions from European Portuguese (pt-PT). The .br domain has the largest registration base of any Latin American ccTLD, and +55 is widely dialed. Brazil uses a unique decimal/thousands separator convention (period for thousands, comma for decimal), which is critical for proper number formatting. Brazil's CPF/CNPJ tax identification system requires specific validation algorithms in applications. The country's massive digital market makes pt-BR essential for any serious international application.
