9750 is the division number for Information Services within the School District of Hillsborough County. (SDHC also refers to these numbers as school numbers.) This number is of significance to anyone exploring the school computer systems; the naming convention for computers at the district rather than at a specific school seems to be prefixing 9750.
I am writing this because I have seen the number many times in my exploration, and finally looked around to see what it signified. A Google search of “9750 site:sdhc.k12.fl.us” yielded a page to search for job openings. (Currently, I have to use a cached version because it is down.) Under the “Support Postings” tab, there is a dropdown where you can choose the location to search for jobs at. There is an option labelled “Information Services (9750)”.
