Do yourself a favor and check to see if you left money anywhere. AAA prorated my rate when I changed car insurances, I completely missed it at the time. Years later, I check the unclaimed and there it is.
If a company has money they owe you, but they can't find you, they turn it over to the State to hold in your name.
Being hosted by michigan.gov gave me peace of mind, but the search is totally non-invasive. I recommend searching your first and last name before filling in the city/zip. I found my name doing a last name search, but as soon as I put the same city in as on the record, it vanished. ymmv
