North Dakota lawmakers are looking into allowing those with out-of-date addresses on their IDs to vote if they have other ways of proving their current address.

This month’s midterm election marked the first since a 2013 law went into effect that ended the practice of allowing residents without an ID to vote if they signed an affidavit swearing that they were eligible to do so. Both the North Dakota secretary of state’s office and two Democratic lawmakers have said they’re working on legislation that could act as a work around, according to the Grand Forks Herald.

“The legislation being drafted is trying to provide an option for those individuals that have not (updated their identification), that they can fall back on something else,” Secretary of State Al Jaeger (R) told the Grand Forks Herald.

The law would allow voters to use bank statements, utility bills or U.S. Postal Service change-of-address forms as proof of address.

State Sen. Mac Schneider (D) and state Rep. Corey Mock (D) said a bill they will introduce will allow voters without an up-to-date ID to cast a provisional ballot that wouldn’t be counted until they proved they were eligible to vote.

North Dakota is the only state without voter registration, due to its size. Having small precincts in rural communities means poll workers can theoretically know everyone who comes into vote. It also has the shortest wait time to vote in the country: 7½ minutes.

North Dakota is one of 31 states that requires identification to vote, according to the National Conference of State Legislatures. Voters must present a current driver’s license, state ID, passport, federal agency ID card, tribal card, state school ID or long-term care identification certificate to vote.
