KL-Certification Ranks First in FCC TCB Data for 2025

An analysis of FCC equipment authorization data for 2025 shows that KL-Certification accounted for 5,436 certifications, or approximately 12.6% of total volume across 18 active Telecommunications Certification Bodies (TCBs).¹

The full-year dataset includes 43,131 certifications and provides a structured view of certification volume, ranking, and market distribution across TCBs.

Key observations:

• Total certifications reached 43,131 in 2025

• Peak activity occurred in December with 5,839 certifications

• The top 5 TCBs accounted for approximately 47% of total volume

• Certification activity is distributed across 18 active TCBs, with a long tail of smaller bodies

A significant anomaly occurred in October 2025, when certification activity dropped to 31 grants due to the U.S. federal government shutdown (October 1 – November 12); this data point is excluded from trend analysis.

The dataset indicates a concentration of certification volume among leading TCBs, alongside consistent seasonal patterns with increased activity toward year-end.
