Thousands of Wisconsin residents could find themselves dropped from the states Do-Not-Call list if they don't register by next month.
More than one million telephone numbers are currently on the states list which protects against telemarketers calling them.
Participants are required to sign up for the program at least once every two years. This September marks the two year anniversary of the program.
The list was set up to require renewal every two years to account for numbers that change as people move.
