 Campus Telephone Number Prefixes

The area code for the Columbus campus is 614. The current university-owned telephone prefixes (or exchanges) for the Columbus Campus, including the Wexner Medical Center and university housing areas, are as follows:

  • Administrative Offices prefixes: 292-xxxx, 247-xxxx, 514-xxxx, and 688-xxxx
  • Wexner Medical Center prefixes: 293-xxxx, 366-xxxx, and 685-xxxx
  • Undergraduate, Family, Graduate and Professional Housing Area prefixes: 688-xxxx

Most university telephone prefixes are Direct Inward Dial (DID) numbers, which means they can be dialed directly from off campus telephones. NOTE: Campus telephone numbers that begin with 514-xxxx are mostly internal campus extensions only and cannot be called directly from an off campus phone. Most of 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 residence hall room with the prefix of “688” from an office phone, you would dial “8” 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.

 Distinctive Ringing and Other Audible Tones

Distinctive Ringing Indicates whether an incoming call is coming from a campus or off campus telephone. “One long ring” indicates the incoming call is coming from another campus phone. “One long and one short ring” indicates the incoming call is coming from an off campus phone.*

Dial Tone – Is a continuous tone indicating dialing may begin.

Busy Signal – Is a repeated buzz tone indicating the number you called is in use or “busy.”

Fast Busy – Is a repeated buzz tone, about twice as fast as a normal busy signal, indicating one of the following scenarios: all circuits are busy, a restricted operation was attempted, or improper use of your telephone.

Activation Tones – Hearing “three beeps followed by a steady dial tone” indicates you can proceed with activating a feature or entering your Authorization Code when placing a long distance call.

Completion Tones – Hearing “beeps followed by silence” confirms that you successfully activated or deactivated a telephone feature.

Ring Again Notification – A cycle of “one long and two short rings” indicates a busy line is now free.*

*NOTE: Distinctive Ringing is a standard feature on all business telephones unless otherwise requested. Distinctive Ringing and Ring Again may cause interference with proper use of fax machines, answering machines and modems and may need to be removed from these type of lines.
