Suburban Cook County voters can now apply for mail-in ballots for the November 8 general election.

Voters have until November 3 to apply for a mail ballot, which will be delivered to mailboxes starting in mid-October, according to Cook County Clerk David Orr's office.

Mail ballot applications can be completed online on the clerk's website. Voters interested in applying online will need the last four digits of their Social Security number, driver's license or state identification card, and an email address.

"Applying for a mail ballot online has become increasingly popular in every election since its inception in 2014," Orr said in a statement Wednesday. "With last election's record-breaking results, it is clear that suburban Cook County residents enjoy the convenience of requesting their ballot and making their election choices from the comfort of their own home."

In the March 2016 primary, there were 31,409 ballots cast by mail in suburban Cook County, a "225 percent increase from the previous primary election," according to Orr's office. About 80 percent of the mail ballot applications for the March primary were submitted online.

Non-suburban Cook County voters can find vote by mail information on their local clerks' websites.
