MADISON, Wis. — Wisconsin elections officials have started mailing postcards to hundreds of thousands of people telling them how to register to vote.

State lawmakers passed a measure earlier this year requiring Wisconsin to join a multi-state consortium that works to identify eligible voters who haven’t registered and informs them how to get on the books.

The state Elections Commission voted in August to comply by sending postcards to 1.28 million unregistered state residents. Commission Administrator Mike Haas says the agency is mailing the first 400,000 to 500,000 postcards on Monday with the rest to follow later this week. Recipients should find them in their mailboxes within nine days.

The effort will cost $225,000. The Pew Charitable Trusts has given the commission a $150,000 grant to defray the cost.
