Usually no. For career fairs, a phone number you personally control long term is usually safer than a school-managed number that may change, forward oddly, or disappear after graduation.
Should you use your college phone number for job interviews? Learn when it is safe, when it creates privacy or continuity problems, and what to use instead.

Should you use your college phone number on a cover letter? Learn when it can work, why it often creates follow-up risks, and which alternatives are safer.
Usually no. A college phone number is only a good choice for job applications if you fully control it, it accepts recruiter calls and texts reliably, and you will keep it long after the application is submitted.
