SK Teleco LLC - 16 Traceback Response Failures - Initial Determination and Show Cause Order

The FCC Enforcement Bureau found that SK Teleco LLC violated its obligation to respond to 16 traceback requests within 24 hours of receipt, a requirement under the FCC's robocall enforcement framework. The order imposes an Initial Determination finding of violation and directs SK Teleco LLC to show cause why further remedies — which may include monetary penalties, mandatory compliance measures, or revocations of authority to terminate traffic on U.S. networks — should not follow.\n\nVoice service providers that originate, transit, or gateway U.S. robocall traffic should treat this action as a signal that the FCC is actively enforcing traceback cooperation obligations. Any provider receiving traceback requests from the FCC or its designees should implement immediate response procedures to meet the 24-hour deadline. Non-cooperation carries enforcement risk, regardless of whether the provider itself initiated the alleged robocalls.
