GoKawiilIf you're bringing a hardware product to market in the US, you need an FCC-accredited test lab. Wireless devices, unintentional radiators, anything that emits RF energy: it goes through a test lab before it can legally be sold.
There are 591 FCC-recognized test labs worldwide. We pulled the complete dataset from the FCC, enriched every record with accreditation status, capabilities, and location data, and built a searchable directory out of it. Here's what the landscape actually looks like.
What "FCC-accredited" actually means
The FCC doesn't run its own test labs. It recognizes private labs that have been accredited by approved Test Firm Accreditation Bodies (TFABs). Organizations like A2LA in the US, MIC in Japan, and BSMI in Taiwan are each authorized by the FCC to certify that a lab meets ISO/IEC 17025 standards for EMC and RF testing.
When a lab gets accredited, it receives a designation number. US labs get numbers like US1291 , Chinese labs get CN1349 , German labs get DE0058 . That designation is what lets a Telecommunication Certification Body (TCB) accept the lab's test results and issue an FCC grant of equipment authorization.
The distinction between test labs and TCBs matters. Test labs do the physical testing: they put your device in an anechoic chamber and measure its emissions. TCBs review the test data and issue the certification. Some labs are also TCBs (67 out of 591), meaning they can test and certify in a single step. The rest are test-only, and their results go to a separate TCB for review.
The dataset: 591 labs across 28 countries
