County Administration & Governance
In Georgia, county governments manage vital public infrastructure, tax assessments, law enforcement, judicial courts, election administration, and public records. The county seat (Atlanta and other municipal headquarters) houses the primary courthouse, commissioners, and sheriff’s department.
All Georgia counties carry a unique 5-digit Federal Information Processing Standard (FIPS) code, where the first two digits (13) designate the state and the remaining three digits identify each specific jurisdiction.
