Telecommunications Certification Body (TCB)

A Telecommunications Certification Body (TCB) is an FCC-recognized third-party organization authorized to issue equipment certifications for radiofrequency devices under U.S. law. TCBs play a key role in the FCC’s equipment authorization program for intentional radiators.

Role and Authority

TCBs are designated by the FCC to evaluate and grant certifications for radio transmitters and other intentional radiators in accordance with 47 CFR Part 2, Subpart J.

They are responsible for:

• Reviewing technical documentation and test reports

• Ensuring compliance with applicable FCC rules (e.g., Part 15, Part 22, Part 24)

• Issuing the grant of equipment authorization via the FCC database

• Supporting post-market surveillance activities

TCBs operate under a Mutual Recognition Agreement (MRA) framework, which enables foreign entities to act as TCBs for the U.S. market and vice versa.
