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: 2025-12. 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.
