The Regional Electoral Court of Rio Grande do Sul (TRE-RS) is the state-level institution of Brazil’s Electoral Justice system, serving voters and supporting the administration of elections across Rio Grande do Sul. Its work includes providing electoral services, conducting judicial proceedings, and sharing official information about voting, candidates, political parties, and electoral rules. The court offers guidance on voter registration, electoral status, polling locations, biometric registration, voting procedures, and election justifications, as well as certificates and document validation.

Voters can access services online, through electoral offices and service points, or by contacting the statewide voter assistance line. TRE-RS also publishes election results, calendars, statistics, court decisions, legislation, and official notices. Its judicial services include the Electronic Judicial Process system, virtual service counters, hearing information, and public case records.

The institution provides resources for polling-place workers, promotes accessibility and inclusion, and supports efforts to counter electoral disinformation and political violence against women. It also maintains an ombudsman service that handles requests for information and public feedback
