Most Calls Examined by Traceback Group Stem From U.S.-based Providers

Representatives of the Industry Traceback Group (ITG) provided preliminary observations on its work in 2025 in an FCC filing posted Thursday in docket 17-59. Since 2020, tracebacks “increasingly end with providers identified as U.S.-based,” rather than foreign-based, the ITG said. More than 30 new providers are identified in tracebacks on average each month, and last year, 110 U.S. and 82 non-U.S. providers failed to respond to traceback requests, it said. “Patterns of repeated and overlapping relationships may indicate intentional strategic obfuscation rather than isolated incidents.”
