Telecommunications Dialing Information



On-Campus Calls to Campus Exchanges: 994, 242, 726

Campus exchanges for the Foggy Bottom, Mount Vernon, and Virginia campuses are as follows:
  • (202) 994-xxxx - Foggy Bottom Campus
  • (202) 242-xxxx - Mount Vernon Campus
  • (703) 726-xxxx - Virginia Campus
When making a call from on-campus to a campus exchange telephone number (994, 242, or 726), please use intra-university calling methods. Departments are charged a 9-cent local call rate for each call dialed through an outside line.

To call another campus exchange telephone number while on-campus, simply dial the five-digit extension. For example:
  • (202) 994-1000 = 4-1000
  • (202) 242-6600 = 2-6600
  • (703) 726-8200 = 6-8200
