Merchants who wish to go door to door need to purchase a traveling merchant permit from the Police Department. The Police will give them a copy of the Do Not Solicit List which will show them which properties to not go to. If you are on the Do Not Solicit List and traveling merchants are still coming to your door, please call the Police Department Non-Emergency at 414-206-3916. However, religious groups and charities are allowed to go door to door.
