How a CNJ number is built
The CNJ number is the standardized unique identifier issued by Brazil's National Council of Justice (CNJ) for every lawsuit in the country. It has 20 digits distributed across 6 fields:
NNNNNNN-DD.AAAA.J.TR.OOOO
- NNNNNNN (7 digits) — sequential case number within the issuing authority - DD (2 digits) — check digits computed via mod-97 - AAAA (4 digits) — year of filing - J (1 digit) — justice segment (1=STF, 3=STJ, 4=Federal, 5=Labor, 6=Electoral, 7=Federal Military, 8=State, 9=State Military) - TR (2 digits) — tribunal code within the segment (e.g., 26 = TJSP) - OOOO (4 digits) — origin unit (court section, district, chamber)
This decoder validates the check digits with the official mod-97 algorithm (CNJ Resolution 65/2008) and identifies the tribunal, segment, state, and region for the vast majority of active processes.
