Register to Vote

You can register to vote in three ways: in person, online, or by mail.

Register in person

You can register in person at local City, Village, and Township Halls in DuPage County or the Election Division’s office and some local libraries. When registering, bring two forms of identification with you, one of which must have your correct address.

Register online (or update your information)

To apply online, you must be prepared to provide:

  • Your Illinois Drivers’ License number or Illinois Secretary of State-issued State ID number.
  • Date the license or ID was issued.
  • The last four digits of your Social Security number.
  • Your birth date

Then go to the Illinois Online Voter Application at
Note: this site may not work if you’re using a VPN; you’ll need to turn it off temporarily. (If you don’t know what a VPN is, you probably don’t have one.)

DuPage County’s Register to Vote page also explains:

Register by mail

Not to be confused with voting by mail!

You can also register by mail using an approved registration application form. You may download one of these PDF forms for printing:

Or you may contact the Election Division to have a form sent to you. Instructions are included on the form for where to mail it.

  • You must mail or deliver this form no later than 28 days before the next election.
  • If you do not receive a confirmation within four weeks of mailing or delivering this form, call the Election Division at (630) 407-5600.

If none of the above work, please call the DuPage County Clerk at:

8:00 a.m. to 4:30 p.m.
Monday thru Friday

None of the automated phone menu options apply; press “0” (zero) to talk to someone. You’ll need to give your name, address, and date of birth.
