A final three-day period for primary election voter registration begins Tuesday with neighborhood agents around the state.

In Salt Lake County, registration agents will be available in their homes from 8 a.m. to 9 p.m. in 712 voter districts Tuesday through Thursday to sign up any residents who want to vote in the Sept. 13 primary election.The various county clerk offices have been closed since Aug. 23, and won't be open for registration by mail or in person until after the primary election. All offices are gearing up for the Nov. 8 general election.

Registrants must sign up with the neighborhood agent located in the potential voter's district.

Voter registration is required for new residents who are eligible to vote if they have lived in the state at least 30 days and are U.S. citizens. Previously registered voters, who have moved to another residence since last voting, or who haven't voted within the last four years, must also register to ensure eligibility for primary voting.
