- Where to request it
- Lake County Clerk — Voter Services Division(847) 377-2311 (Voter Registration) | fax (847) 984-5827 | [email protected] | 18 N. County St., Room 101A, Waukegan, IL 60085-4364
- Cost
- $10.00 setup fee + $1.00 per 1,000 records (rounded up to next 1,000). For ~530K Lake voters this is $10 + $530 = roughly $540, but in practice committee orders typically scope by precinct/district. Call (847) 377-2311 for exact quote.

Requester must be a registered IL political committee or governmental entity. Payment must be a committee check or money order made payable to 'Lake County Clerk.'
- Turnaround
- Typically 1-2 weeks after application + payment clears.
- Use restrictions
- Same statutory framework — committees/government only, bona fide political purpose affidavit, no commercial use, no resale. Payment specifically by committee check or money order — no personal checks or credit cards.
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.
