From the bottom of this article from today:
Heard from Link that the first day enrollment number was 15,465 students. The official fall enrollment number will be confirmed on census day, Sept. 21.

From a UND blog post in August 2025:
UNDâs first-day headcount this week came in at 15,440.

The Herald article uses the word enrollment, which is different than head count I believe. Not sure if comparing apples to apples here or not
