Area Code and Exchange For Your Office Extension.
Because of the large number of phones installed at Marple Campus and Malin Road Center, the College uses external phone numbers from several different exchanges. The following two tables permit you to determine your area code and exchange based on the extension used for the phone in your office. For example, if your office extension at Marple Campus is 1299, then your external telephone number is 610-325-1299. If your office extension is 5182, your external telephone number is 610-359-5182. Note that all extensions in the 6000 series both at Marple and Malin Road cannot be dialed from outside the campus.
