Aug. 31 is the last day to sign up for the next no-call list, which goes into effect Oct. 1. Consumers can always sign up later, but they will not be on the list until Jan. 1.

To place your number on the list, simply go online to NoCall.Wisconsin.gov or dial 1-866-966-2255 (1-866-9No-Call). This website and toll-free number are available 24 hours a day.

Consumers must sign up every two years. If you are not certain that you signed up within the last two years, you should sign up again to be sure you are not dropped from the list.
