Campus Telephone Number Prefixes
University-owned telephone prefixes for the Columbus Campus are 292-xxxx, 293-xxxx, 247-xxxx and 688-xxxx. These prefixes are Direct Inward Dial (DID) numbers, which means they can be dialed directly from off campus telephones. Additionally, campus telephone numbers that begin with 514-xxxx (new April 1, 2005) are internal campus extensions only and cannot be called directly from an off campus phone. These internal extension numbers can only be dialed directly from other campus telephones using five-digit dialing (4-xxxx).
Five-digit Dialing
The university utilizes five-digit dialing when placing calls from one university telephone to another. For example, when calling a university office with the prefix of “292” from a residence hall phone, you would dial “2” plus the last four digits of the telephone number. Five-digit dialing is also used when calling OSU Regional Campuses. There is no charge for placing “campus to campus” calls (five-digit dialing). However, charges may apply when placing other types of calls from campus telephones. These charges are denoted in the appropriate sections.
