The formation of electoral alliances began in early April 2024, with several coalitions announcing their participation. On 7 April, the parties
Amarillos por Chile,
Democrats, and Sentido Común joined forces to create the "Centro Democrático" alliance for the municipal elections. The following day, the
Christian Social Party registered its own electoral pact with independent candidates, scheduling mayoral primaries in key communes including
Independencia and
Concepción. The center-right
Chile Vamos coalition, comprising
RN, the
UDI, and
Evópoli, formally registered on 9 April. Their pact included provisions for primaries to select both regional governor and mayoral candidates. For municipal council elections, Chile Vamos initially filed three separate lists—one for each member party alongside independent candidates. However, in a strategic shift the next day, the UDI and Evópoli lists were merged into a single pact with separate sub-sections for each party. Also on 9 April, the governing coalition's "Contigo Chile Mejor" alliance was registered, bringing together the ruling parties with the
Christian Democratic Party. For council elections, the coalition declared four distinct lists to field candidates across different municipalities.
