What Is FCC Certification?

FCC Certification is a mandatory approval process required by the Federal Communications Commission (FCC) for electronic devices that emit radio frequency (RF) energy and are marketed or sold in the United States. The certification ensures that products comply with FCC regulations designed to prevent harmful electromagnetic interference and maintain the integrity of communication networks.

Whether you manufacture wireless devices, consumer electronics, industrial equipment, or IoT products, obtaining FCC certification is often a critical step before entering the U.S. market.

Why FCC Certification Is Important

FCC certification serves several important purposes:

• Ensures compliance with U.S. regulatory requirements

• Prevents electromagnetic interference with other electronic devices

Testing must be performed by an accredited laboratory, and the application must be reviewed by an FCC-recognized Telecommunication Certification Body (TCB).

2. Supplier's Declaration of Conformity (SDoC)

Certain products may qualify for the SDoC process instead of full certification. Manufacturers are responsible for ensuring compliance and maintaining documentation.

Examples include:

• Computer peripherals

• Digital devices

• Information technology equipment

3. Verification (Historical Process)

Many verification requirements have been incorporated into the SDoC framework under updated FCC regulations.

FCC Certification Process

• FCC Part 95

The applicable rule depends on product functionality and operating frequency.

Step 2: Product Evaluation

Technical experts evaluate:

• Wireless technologies

• Frequency bands

• Antenna configurations

• Power output levels

• Product design

This assessment determines the required testing scope.

Step 3: FCC Testing

The product undergoes testing in an accredited EMC and RF laboratory.

Common tests include:

Radiated Emissions Testing

Measures electromagnetic energy emitted by the device.

Conducted Emissions Testing

Evaluates RF noise transmitted through power lines.

RF Exposure Testing

Assesses user exposure to radio frequency energy.

Bandwidth and Power Measurements

Verifies compliance with frequency and power limits.

Spurious Emissions Testing

Measures unwanted emissions outside the intended frequency range.

Step 4: Documentation Preparation

Required documentation may include:

• Technical specifications

• User manual

• Product photographs

• Internal photographs

• Schematics

• Block diagrams

• Test reports

• RF exposure reports

• Label artwork

Step 5: TCB Review

An FCC-recognized Telecommunication Certification Body reviews all submitted materials and test results.

Step 6: FCC Grant Issuance

Once approved, the FCC issues a Grant of Equipment Authorization.

The product receives an FCC ID and may be legally marketed in the United States.

What Is an FCC ID?

An FCC ID is a unique identifier assigned to certified products.

Example:

FCC ID: XYZ-123456

The FCC ID consists of:

• Grantee Code (assigned by FCC)

• Product Code (assigned by manufacturer)

This identifier allows regulators, importers, distributors, and consumers to verify compliance information.

FCC Part 15 Requirements

FCC Part 15 is one of the most commonly applied regulations.

It governs:

• Unintentional radiators

• Digital devices

• Wireless communication products

Products must not:

1. Cause harmful interference.

2. Accept any interference received.

Common devices subject to Part 15 include:

• Computers

• Monitors

• Wireless routers

• Smart devices

• Consumer electronics

FCC Certification for Wireless Products

Wireless devices face additional testing requirements because they intentionally transmit RF signals.

Examples include:

• Bluetooth speakers
