Cal State Fullerton Area Code Changing to 657 [Telecom]

FULLERTON CALIFORNIA - May 27, 2009. Beginning May 30, Cal State Fullerton will have a new area code - 657. Cal State Fullerton's main campus in Fullerton and CSUF Irvine Campus will be using this latest area code assigned within Orange County.

The additional area code was added by the California Public Utilities Commission to meet the increasing needs for additional phone numbers from throughout the county, explained Marci Payne, manager of telecommunications for Cal State Fullerton.

CSUF has a four-digit internal dialing plan covering the main campus at Fullerton (area code 714, recently overlaid by 657) and a branch campus at Irvine (area code 949).

Before the University's area-code switch, the dialing plan was:

0 = Campus operator 1xxx = 4D extensions at Irvine Campus (949-936-1xxx) 2xxx = 4D extensions at Fullerton Campus (714-278-2xxx) 3xxx = 4D extensions at Fullerton Campus (714-278-3xxx) 4xxx = 4D extensions at Fullerton Campus (714-278-4xxx) 5xxx = 4D extensions at Fullerton Campus (714-278-5xxx) 6xxx = 4D extensions at Fullerton Campus (714-626-6xxx) 7xxx = 4D extensions at Fullerton Campus (714-278-7xxx) 82xx = 4D extensions at Fullerton Campus (714-278-82xx) 83xx = 4D extensions at Fullerton Campus (714-278-83xx) 84xx = 4D extensions at Fullerton Campus (714-278-84xx) 85xx = 4D extensions at Fullerton Campus (714-278-85xx) 88xx = 4D extensions at Fullerton Campus (714-626-88xx) 9 = Outside line (local and toll)

Effective May 30, all extensions were switched to 657-278. The new dialing plan is:

0 = Campus operator 1xxx = 4D extensions at Irvine Campus (657-278-1xxx) 2xxx = 4D extensions at Fullerton Campus (657-278-2xxx) 3xxx = 4D extensions at Fullerton Campus (657-278-3xxx) 4xxx = 4D extensions at Fullerton Campus (657-278-4xxx) 5xxx = 4D extensions at Fullerton Campus (657-278-5xxx) 6xxx = 4D extensions at Fullerton Campus (657-278-6xxx) 7xxx = 4D extensions at Fullerton Campus (657-278-7xxx) 8xxx = 4D extensions at Fullerton Campus (657-278-8xxx) 9 = Outside line (local and toll)

Irvine campus extensions officially changed to 657-278-1xxx (creating a

657 island inside 949). However (as of 06/11/09) it was still possible to reach Irvine extensions at the old 949-936-1xxx numbers.

I guess this change was made for a couple of reasons:

- It allows the University to consolidate all extensions in 657-278, eliminating the 949-936 and 714-626 anomalies.

- It allows the University to utilize previously unavailable number blocks 657-278-9xxx and 657-278-0xxx by switching to a 5-digit internal dialing plan.

Some authors (notably former TD contributor Mark Cuccia) have noted that this change violates an underlying argument in favor of overlays: "nobody has to change area codes." Well, that's true, but it doesn't preclude Universities and similar bulk number users from voluntarily switching to the overlay area code.

Drifting off topic a bit, and it appears Cal State Fullerton does not do this, a fair number of campuses have SIP based telephone access. I don't know if all the phones are SIP based with a bridge to POTS or if it's the other way around. But, some campuses doing this are listed at

Seems like a terrible waste of an area code unless it will be used as an overlay for the entire 714 NPA.

Ten seconds looking at nanpa.com reveals that 657 was added as an overlay for 714 back in September.

After I posted this I checked the California PUC web site. It is an overlay for the entire 714 NPA.
