Area Code Prefix Change



909/951 Area Code Split & UCR Campus Prefix Change

As many of you already know, Riverside will be receiving a new area code (951) beginning July 17, 2004, as mandated by the California Public Utilities Commission. A "grace period" will exist from July 17 through October 29, 2004, during which callers to campus will have the option of using either 909 or 951. Beginning October 30, 2004, the 909 area code will no longer be valid for calls destined for campus. If you have a cellphone with a 909 area code, please check our cellphone information page.

What many of you may not know is that UCR has finally "run out" of 787 numbers. Computing and Communications (C&C) has acquired all numbers associated with the new 827 prefix, which spell out "UCR", as in UCR-BEAR (827-2327). Our prefix change will occur in parallel with the 909/951 area code split. See Why Change Now? for details.
