 CALIFORNIA STATE TELEPHONE CENTRAL OFFICE'S

 

                                    

AREA CODE 559

Area code 559 was the result of the split of area code 209 which at one time covered a major portion of California's Central Valley. The split occurred in November 1998 and the southern portion of the region took the 559 code. This area covers mostly agriculture and farming yet has some larger urban areas comprising of the Fresno and Visalia-Hanford metropolitan areas.

The Visalia office opened in April, 1948, replacing the manual exchange three blocks away at 129 S. Church Street. It was originally a step-by-step office. There are two very high-ceilinged floors above ground. The switches, test-board and trunking were on the first floor. Operator Services (Traffic) cord switchboards and DA took up the second floor.

Visalia was once a Class 4 Toll Center under the AT&T Direct Distance Dialing hierarchy plan with direct trunk groups to the Fresno Class 3 Primary Center.

The brown concrete insets in the walls cover the windows that fell victim to the Cold War.

If you look closely in the top picture you can actually see the shadow of the old Pacific Telephone signage, with the 1969 Bell System logo. Pacific Bell removed the sign in 1984, when they placed their red star-key emblem on the north and west faces of the building. Those were later replaced with SBC signage and now has new owner AT&T displayed.
