The state is expected to release the first wave of registrations by the end of next week.
But the numbers won’t be finalized until the next day, when Michigan and its 27 other counties release voter registration lists for voters who applied online.
Those lists will be used to fill in the state’s 3 million voter rolls.
Some county election officials and political operatives have urged people to register online, arguing that the system has the ability to help prevent fraud and increase turnout.
But state elections officials are warning that if voters are still waiting in line on Election Day, they may not have a say in who their votes are counted.
The state’s website says the process can take up to three days.
In California, the first phase of the voting system’s roll-out will begin Tuesday, as state officials work to ensure that voters can register online and vote in the November elections.
It will take several days for the first batch of new registrations to be counted.
California is also working to roll out a voter-registration system similar to the one in Georgia and South Carolina.
That system will be open to the public for the next few months.
