List of political parties in Brazil
Above the broad range of political parties in Brazilian Congress, the Workers' Party, the Brazilian Democratic Movement, the Social Liberal Party and the Democrats together control the absolute majority of seats in the Senate and Chamber of Deputies. Smaller parties often make alliances with at least one of these four major parties.
Since 1982 Brazilian political parties have been given an electoral number to make it easier for illiterate people to vote. Initially, it was a one-digit number: 1 for PDS, 2 for PDT, 3 for PT, 4 for PTB, and 5 for PMDB. When it became clear that there was going to be more than nine parties, two-digit numbers were assigned, with the first five parties having a "1" added to their former one-digit number. Often political parties change their names but retain their number.
