The mandatory certification mark for wireless transmission devices is used to prove that the device complies with US radio frequency (RF) technical specifications and electromagnetic compatibility (EMC) requirements, avoiding interference with other wireless devices, and is a legal prerequisite for wireless devices to enter the US market.

一、核心作用

FCC-ID 是设备通过 FCC 认证后获得的唯一标识（格式为 “授权码 + 产品码”，例如2ABT2-XXXX），需永久标注在产品或包装上，便于 FCC 追溯设备合规性，同时也是海关清关、市场销售的必要凭证。

二、适用范围

Devices that actively emit radio waves, including but not limited to:


    三、认证流程
    FCC-ID 认证属于 “FCC ID 认证” 类型（区别于 DoC/SDoC 自声明模式，后者适用于低风险非无线设备），流程如下：


    1. 选择认证类型：确认设备属于需 FCC-ID 认证的无线发射设备；

    2. 测试准备：提供产品技术资料（电路图、PCB 布局、用户手册、物料清单等）；

    3. Submission for review: Submit test reports, product information, and other documents through the TCB (Telecommunications Certification Body) authorized by the FCC. After the TCB review is approved, the FCC will assign a unique FCC-ID;

    4. Identification and Compliance: Permanent labeling of FCC-ID (such as "FCC ID: XXXXX-YYYY") on the product body or packaging, and retention of certification documents for customs or market inspections.

    四、关键注意事项

    • Testing standards: Different devices correspond to different FCC regulations (such as Part 15 for civilian low-power devices and Part 24 for cellular mobile devices), and precise matching is required;

    • Validity period: FCC-ID does not have a fixed validity period, but re certification is required when there are design changes (such as circuit or antenna modifications) or updates to FCC standards;
