Communications The first telephone operations in Centralia began in 1891 when the city was connected to the Sunset Telephone and Telegraph Company (STTC) located on Tower Avenue. The first customer was a neighboring pair of attorneys. The STTC recorded 23 subscribers the following year, falling to only six in 1893, but began to slowly rebound at the turn of the century. By 1910, over 500 customers subscribed to the line, serving approximately 1,000 customers in the Twin Cities when the STTC was renamed in 1916 as the Pacific Telephone and Telegraph Company . By the mid-1960s, the area was served by Pacific Northwest Bell and had a subscriber list of over 12,000 between Centralia and Chehalis.
