The official "Wheel of Fortune" website does not post the previous night's winning SPIN ID, as of 2015. However, sites such as WheelOfFortuneSolutions.com, WheelSpinID.com and JimPettis.com post the winning SPIN ID numbers from recent episodes.
A SPIN ID is a special identification number available to registered viewers of the "Wheel of Fortune" game show. Each night, the show displays one identification number along with a prize. If the person who owns that number logs into the show's website within 24 hours and verifies her contact information, she may win that prize. Winning is contingent upon meeting contest qualifications and receiving approval from a show team member.
