About Korean KC / RRA IDs

Korean equipment approvals can appear under KCC, MSIP, RRA, NRRA, or KC identifiers depending on the rule set and approval year. Radio and EMC products are commonly published by the Radio Research Agency, while electrical and electronics safety certifications are commonly published through Safety Korea and KATS systems.

FCCID.io lists English fields first when available, keeps the Korean source text as the authoritative alternate, and uses legacy FCCID.io RRA data only as supplemental fallback.
