Cogent Communications Company

This memo is essentially a survey.  We appreciate the patience with the state assessment of telephone companies, and who does what assessments.  

Cogent Communications acquired Sprint Wireline in 2023, but Cogent is not state assessed, and does not file any paperwork with the Colorado Public Utility Commission. Cogent claims to be filing at the county level, and we would like to know what counties have property declarations. Cogent has maintained an active status with the Colorado Secretary of State since 2000.

If your county does not have filings from Cogent Communications, there is no need to reply. If your county has Cogent filings, please reply with an email to Mark Walker at

In addition, please include how many years Cogent has been making filings in your county.
