Phone Lines

The university provides both Direct Inward Dial (DID) and non-DID phone lines. If you have a DID number, your callers may use the prefix and extension to call your phone directly. If you have a non-DID number, callers must dial (626) 815-6000 and enter your extension.

The following are the university Direct Dial extensions listed with their corresponding prefixes. These can be dialed with the pattern (626) + Prefix + Ext.

Area Code Prefix Extension
(626) 812 30xx
(626) 815 20XX, 21XX, 38XX, 45XX, 46XX, 50XX, 53XX, 54XX, 60XX, 61XX, 63XX, 64XX
(626) 804 25XX, 26XX
(626) 387 57XX, 58XX
(626) 857 22XX, 24XX

Any other extension not listed above is considered a nondirect extension and can be dialed via the automated attendant at (626) 815-6000.

To allow the communications operator the opportunity to answer incoming calls efficiently, provide your callers with your DID number or 4-digit extension. Use the DID lines and the automated attendant at (626) 815-6000 whenever possible.

If you receive a call from a person who needs to speak with another department or individual, transfer the caller directly to the requested extension. This prevents the caller from being bounced around several times before getting in touch with the intended destination.
