Each school/district has their own version of Infinite Campus. In order to connect your device to your school's version of Infinite Campus we use a short six character code (aka your District ID) to map your school's site. Don’t have a Campus Portal account? All Campus Portal accounts are provided by your school.
The Get Your District ID button was removed from the Campus Portal in October 2016. You may now obtain your District ID by clicking here.
Short answer: Yes, it can.
Long answer: Yes, it can change if the URL to access your district's version of Infinite Campus changes. Usually if a school changes the URL for Infinite Campus, we get notified and update the URL for the original District ID. In this situation, both district codes work for the Mobile App.
