The Michigan Lottery claim centers in Lansing, Detroit, Grand Rapids, Livonia, Saginaw and Sterling Heights will be closed on Friday while the Lottery’s accounting system is upgraded.

All regularly scheduled drawings will continue on Friday.

Because Lottery claim centers will be closed Friday, bank claim centers and Secretary of State offices also will be unable to process Lottery claims.

All Lottery offices will reopen on Monday at 7:45 am.
