Voter Registration Name Change in Missouri

A voter registration name change in Missouri is free and usually takes about five minutes. You can usually update online through the official Missouri voter registration page.

Update your registration after your Missouri driver's license shows your new name, since most registration forms ask for your current license number and the name on it.

Under the National Voter Registration Act ("motor voter"), updating your license at the Missouri Department of Revenue, Motor Vehicle and Driver Licensing Division usually offers to update your voter registration at the same time. Say yes and you may not need a separate step at all.

One warning: don't assume it worked. Confirmation can lag by weeks, and a mismatch between your ID and the poll book is exactly the kind of surprise you don't want on election day. Verify on the official Missouri page a couple of weeks after your DMV visit.

Tell your local election authority about the name change before the election; the Secretary of State's guidance is to have your form postmarked by the fourth Wednesday before it. Missouri law (RSMo 115.167) sets no cutoff for the notice, and lets you vote once under your old name if you tell the election judges at the polling place first. The law: RSMo § 115.167 and Missouri Secretary of State: register to vote. Update well ahead of any upcoming election so your registration reflects your new name at the polls.

If an election is close and you've missed the update window, call your county election office. In many places you can still vote under your former name with your current registration, and some states offer same-day corrections. The rules vary, so ask before you skip voting.

• Your Missouri driver's license or state ID (ideally already showing your new name)
• Your current residential address
• The last four digits of your Social Security number (some forms)

There is no fee to update voter registration in any state. This step is also a good prompt to update your name with your county property records and jury-duty notices, which pull from the same rolls.
