The Federal Communications Commission of the United States, whose English name is FCC (Federal Communications Commission), is responsible for regular interstate and international communications, such as those related to televisions, wires, satellites, and cables. It covers more than 50 states in the United States, Colombia, and the U.S. territories, and is tasked with ensuring the safety of radio and wire communication products related to life and property. 

Regarding FCC ID 

FCC ID: This is used for general radio product applications. Equipment applicable to this method includes various short-range, low-power transmitters, mobile phones, Bluetooth devices, WLAN (2.4G, 5G) devices, etc. The TCB1 agency reviews the test data and materials submitted by third-party testing institutions. If they comply with FCC rules, a certificate will be issued to the applicant. 

The required documents for FCC ID certification 

1. Application form; 2. Product sample; 3. Product manual; 4. Product label; 5. Circuit schematic diagram; 6. Circuit principle description; 7. Circuit block diagram; 8. Certification authorization letter; 9. Confidentiality agreement. 

The composition of the FCC ID number 

FCC ID = Grantee Code Product Code

a>. The Grantee Code is the official company code registered on the FCC website, consisting of 5 digits or letters. This 5-digit number is provided by the FCC and is not set by the customer. Once the application is successful, it becomes a fixed number and serves as the first 5 digits for all FCC ID numbers applied by this company. 

b>. Product Code (Product Code) is composed of numbers, letters and dashes (-), and should not exceed 14 characters in total. It is customizable by the customer. 

FCC ID application materials requirements 

1. Application Form: When filling out the application form, the customer must provide accurate and true information about the applicant and the manufacturer. When checking the sample machine functions, it is necessary to match each one with the actual functions of the sample machine. 

2. Product samples: At least three sample machines need to be provided. One should be in normal working condition, and two should be capable of frequency setting. One of them must have an RF test line soldered on. 

3. Product Manual 

4. Product label: The FCC ID number must be printed on it. If there is no Grantee Code and Product Code, "XXXX" can be used. Warning messages need to be printed for prototype devices with a volume larger than the palm. For smaller prototype devices, the warning messages can be printed on the instruction manual. Specific requirements can be referred to KDB 784748. 

5. Circuit schematic: The information provided in the manual should be consistent with the functions of the certified prototype; the schematic diagram must also correspond one-to-one with the prototype provided by the certification. 

6. Circuit Principle Description: Use words to describe the principle of the prototype, and list the key components and crystal oscillator. 

7. Circuit block diagram: It should be in one-to-one correspondence with the schematic diagram. Key components and crystal oscillators need to be listed. 

Regarding FCC SDOC 

SDOC: Applicable to ordinary products without wireless functions, such as monitors, ordinary household appliances, lighting fixtures, etc. Includes personal computers and their peripheral devices; household appliance equipment; power tools; audio and video products; lighting fixtures; toys; security products, etc. 

SDOC certification can be further divided into 

The certificate issued by the TCB institution (just like the FCC ID application process, submit the report and materials to the TCB institution for review. If the review is successful, the TCB institution will issue the certificate) 

2. The certificate issued by the A2LA2 laboratory. 

The required documents for SDOC certification 

Application form 

2. Product samples; 

3. Product Instruction Manual 

4. Product nameplate; 

5. Circuit schematic diagram; 

6. Circuit principle description; 

7. Circuit block diagram; 

8. Certification Authorization Letter 

9. Confidentiality Agreement; 

An SDOC statement is also required. This statement must be signed by the client, the American importer, company, distributor, etc. In short, the SDOC statement must be signed by a local company in the United States. 

TCB1: Fully accredited by ANSI under ISO/IEC 17065 and recognized by the Federal Communications Commission (FCC) as a Telecom Certification Body (TCB), which enables the certification of telecom radio equipment submitted for certification in accordance with FCC Rules and Regulations.
