Hey there, hi there, ho there, Dick, and welcome to
planDisney. Since I started using MagicBands in 2014, I have found it more enjoyable to tap my way through Walt Disney World Theme Parks and Resort hotels without having to pull out my wallet or wear a lanyard where I kept my Key to the World Card.
The ID number on the back of
MagicBands has a 12-character repeatable alphanumeric and all 36 characters could be A-Z or 0-9 in each slot. The Serial Number differs depending on the MagicBand. Some have a 9-character repeatable alphanumeric and others, like the MagicBand+, have a 16-character repeatable alphanumeric again with each slot having 36 options.
I hope this helps answer your question. Please free to
reach out to me directly for any follow-up questions or Disney vacation planning advice.
Enjoy making many Magical Memories.
