Telephone Dialing Instructions (for Students)

Services: 

Lehigh University is located in the 610 area code. 610 also has two overlay area codes (484 and 835), so all calls to and from campus must be dialed using the full 10 digits.

Students using a Personal Security Code (PSC) to make long distance calls will dial calls as directed below and will be prompted, by a beep, to enter the PSC after dialing the full number. If you need your PSC, please contact Telecommunications at x85300 or email intel@lehigh.edu.
