Dormant RespOrg

This phone company is dead or nearly dead — almost zero numbers and little or no activity. Sometimes called a "zombie" RespOrg because they just won't die.

Last seen with active numbers: 2026-01. Nothing in any monthly snapshot since.

The trajectory chart below shows the full history. The code may have been transferred, retired, or reassigned to a new operator that hasn't begun activating numbers yet.

Summary

Formerly Century Link, among other names, Lumen is a large telecom company that's grown through numerous acquisitions and of course has multiple resporgs and systems and probably numerous numbers lost in the cracks. They also work with a number of resellers, though not as much as they used to. This makes finding the right segment of the company and the actual company providing the service especially hard.
