List of telephone company buildings. This is a list of notable telephone company buildings.  

Telephone company buildings have played a key role in the telecommunications industry for more than a century.  In 2008 it was stated that "the job for which these unassuming but ubiquitous brick houses were built, and the technology within them, are changing dramatically.  In fact, it's tough to say what the CO will look like 10 years from now."  Some challenges are "far higher power densities, heat dissipation requirements and power feeds than we ever built those locations for in the past," said Pieter Poll, chief technology officer for Qwest Communications.

A number of telephone company buildings have been listed on the U.S. National Register of Historic Places for their architecture; see :Category:Telecommunications buildings on the National Register of Historic Places.
