- Where to request it
- Jefferson County Clerk - Election Center1000 E Liberty St, Louisville, KY 40204; phone (502) 574-6100; [email protected]
- Cost
- No separate county-level price list -- SBE charges a subset fee at reasonable-price discretion (well below the $2,000 statewide rate). Confirm with SBE.
- How to request
- Per KY structure, county-only voter data must be requested from the State Board of Elections using SBE-84 with the county/precincts specified in the Special Requests section. The Jefferson County Clerk maintains the local registration data but refers data-extract requesters to SBE. Walk-in/inspection of individual records may be possible at the Clerk's office for permitted purposes.
- Turnaround
- 2-3 weeks via SBE.
- Use restrictions
- Same eligibility gate as statewide (SBE-84 certification). No commercial use. Cannot be resold.
Costs and rules change, so confirm the current details with the office before you order. Once you have the file, we handle loading it, cutting turf, and getting your volunteers knocking.
