Naperville residents who want to vote before Election Day have clear options, but the process differs depending on whether you live in DuPage County or Will County. The early‑voting window closes at 5 p.m. on Monday, Nov. 2, 2026, giving voters a final chance to cast a ballot ahead of the Nov. 3 Midterm General Election.
How to Determine Your County
Naperville straddles two counties. Most of north Naperville falls within DuPage County, while the southern portion—roughly south of 95th Street—is in Will County. To confirm your county, check your property tax bill, voter registration card, or use the address lookup tools on the DuPage County Clerk or Will County Clerk websites.
DuPage County Early‑Voting Sites
DuPage County operates 24 permanent early‑voting locations. While the full list and a map are available on the DuPage County Clerk’s early‑voting page, the sites most convenient for Naperville voters include the following:
- Naperville City Hall – 200 West Jefferson Street
- Naperville Public Library – 200 West Jefferson Street
- St. Laurent’s Community Center – 1500 West 55th Street
All DuPage sites are open from 8 a.m. to 8 p.m. Monday through Saturday. For questions, call 630‑407‑5600 (English) or 630‑407‑5608 (Spanish).
Will County Early‑Voting Sites
Will County provides two early‑voting locations within Naperville:

Both sites are open from 8 a.m. to 7 p.m. Monday through Saturday. For assistance, call 815‑740‑4615.
Mail‑Ballot Options
Online voter registration for this election closed on Oct. 18, but eligible residents may still register in person at any early‑voting site. The City of Naperville advises bringing two forms of identification that show your current name and address. If you have moved or legally changed your name since your last registration, you must re‑register.
DuPage County voters who have already received a mail ballot must ensure it is postmarked by Election Day, Nov. 3, to be counted. DuPage offers a BallotTrax service for tracking ballot status. Will County voters can drop completed mail ballots in the drop box at the 95th Street Library or any other Will County drop box.
Election‑Day Polling Places
On Election Day, polls are open from 6 a.m. to 7 p.m. Voters must go to their assigned polling place, which can be verified on the respective county clerk’s website. In Naperville, the Nichols Library, Naper Blvd. Library, and the 95th Street Library will serve as Election‑Day polling locations.
