Wisconsin DNR Customer ID Number required to register for safety courses Anyone registering for any type of Wisconsin recreational safety certificate is now required to obtain a Wisconsin DNR Customer ID Number before the completion of any recreational safety class. Students will be required to provide their DNR Customer ID Number along with their personal information to the instructor. Obtaining a DNR Customer ID Number is free and can be done by calling the DNR Customer Service Center at 1-888-936-7463 between 7 a.m. and 10 p.m. daily, or by visiting a DNR Service Center during their regular scheduled hours. FOR MORE INFORMATION CONTACT: Todd Schaller (boating safety)- (608) 267-2774 or Tim Lawhern (hunter education) - (608) 266-1317 This is something I did not know untill I was just poking around the DNR website. Thought I would post it for others if they have anyone taking classes in the future and save some last minute hassles.
