Washington — It’s Super Tuesday, your state is one of the 15 holding its primary or caucuses and you forgot to register to vote. 

Is it too late? 

In some states, yes, it’s too late. But if you live in one of about half of the states that allow same-day voter registration, proceed to your polling place. 

Check below to see if your state allows you to register when you show up to vote. 

Alabama

Alabama does not allow same-day voter registration. The state requires voters to register at least 15 days before an election. 

Alaska

The Alaska Republican Party says it allows same-day voter registration for its caucuses. (The Democratic primary is April 6.) Voters should bring an ID with them. Polling sites may be different than usual elections, since the caucuses are run by the political party, not the state’s Division of Elections. Find caucus sites here. 

Arkansas

Arkansas does not permit same-day voter registration. The deadline to register is 30 days before an election. 

California

California allows same-day registration for those who missed the deadline to register by mail or online (both 15 days before an election). A driver’s license, California identification card number or the last four numbers on your Social Security card are needed to register. Find your polling place here. 

Colorado

Colorado’s deadline to register by mail and online was eight days before the primary, but the state allows in-person voter registration through Election Day. All voters need to bring a valid ID. Check your polling location here. 

Maine

Maine also allows same-day voter registration for those who did not submit an application by Feb. 13. Bring an acceptable proof of identification. Look up your polling place here. 

Massachusetts 

The deadline to register to vote in Massachusetts was 10 days before the primary. 

Minnesota

Voters in Minnesota have to submit their online or mail applications at least 21 days before an election. But the state allows same-day voter registration if that deadline is missed. Voters who register on Election Day need to show proof of residence before casting a ballot. Find your polling place here. 

North Carolina

North Carolina permits same-day voter registration during the early voting period, which ended March 2. Same-day registration on Election Day is not available for most voters. The exceptions include voters who became naturalized U.S. citizens or felons who regained voting rights after the regular voter registration deadline, which was Feb. 9. Same-day registrants must provide proof of where they live. Look up your polling place here.
