[10] The building was topped off in July 1975; however, the company elected to forgo a ceremony due to perception concerns in light of a then-recent rate increase proposal that was to add $64 million in revenue.

[11] The building was dedicated on November 22, 1976, in a ceremony featuring then-Governor Dan Evans and various politicians and business leaders as well as Don Ameche, the actor who portrayed Alexander Graham Bell in the 1939 biographical film about him; the total cost of construction was estimated at $40 million.

A naming contest for the building resulted in the selection of "1600 Bell Plaza", proposed by company employee Bev Ardueser, from 2,000 entries.

[13][14] That same year, the company listed the property for sale; a tentative deal with an unknown buyer fell through amid the Great Recession.

[6][14] In April 2012, a year after acquiring Qwest Communications, CenturyLink sold the building to New York real estate investment firm Clarion Partners for $137 million.
