About Lumen Technologies

Lumen Technologies, Inc. (formerly CenturyLink, Inc.) is a public telecommunications company headquartered in Monroe, Louisiana, offering network, security, cloud, voice, and managed communications services through fiber optic and copper networks, data centers, and cloud computing infrastructure.[1] The company has approximately 29,000 employees and is listed on the NYSE under ticker LUMN with reported revenues of $12,690 million.[2][5]

Affiliations: Lumen acquired Level3 Communications (formerly a separate RespOrg operator); Level3 is now part of Lumen Technologies.[1]

Toll free / RespOrg activity: No toll-free or RespOrg-specific news found in search results. Note: User query references RespOrg code JSS01, website Level3.com, and HQ in Arlington Heights, IL—these details do not match the search results, which consistently identify Lumen's HQ as Monroe, Louisiana. Level3 Communications was acquired by CenturyLink in 2015; the discrepancy requires verification against primary FCC RespOrg databases and SEC filings.

AI-generated summary (confidence: low), last updated 2026-04-30. Verify against primary sources before quoting.
