The SOS: 'From the second Tuesday before an election to the day before the election, you may vote a no-excuse absentee ballot in person' at a site your election authority designates, until 5:00 PM the day before the election. For Nov 3 that is Tuesday, October 20 through Monday, November 2, 2026 (STLPR: 'In-person no excuses needed absentee voting begins: Oct. 20'; KCUR: 'Oct. 20-Nov. 2, 2026'). Bring a photo ID. No notary is needed in person. St. Louis County has 21 sites: the Board of Elections HQ (725 Northwest Plaza Dr., St. Ann) plus 20 satellites, including eight county library branches (Cliff Cave, Clark Family, Daniel Boone, Grand Glaize, Grant's View, Lewis & Clark, Mid-County, Thornhill), the St. Louis Galleria, STLCC Meramec, UMSL, Olivette City Center, Wildwood City Hall, North County Rec Complex, Dellwood Rec Center, JFK Community Center, and several churches.

Your election office: St. Louis County Board of Elections
314-615-1800
725 Northwest Plaza Dr., St. Ann, MO 63074 (the county board, not the City of St. Louis board downtown). Mon to Fri 8 a.m. to 4:30 p.m.
What to bring
Photo ID required in person.
No ID? On Election Day you can cast a provisional ballot. It counts if either (a) you return to the same polling place before 7:00 PM with an acceptable photo ID, or (b) the election authority finds the signature on your provisional envelope matches your voter registration record. You get a stub with instructions to check whether it counted. Most registered voters' provisional ballots do count on the signature match, but don't gamble if your ID is at home. In-person absentee voting (Oct 20 to Nov 2) is different: the Secretary of State says 'In person absentee voters are not eligible for a provisional ballot,' so bring your photo ID when you vote absentee in person.
