FCC ID vs. SDoC: Which Does Your Amazon Listing Actually Need?
Updated: Sep 22
Published by US Compliance Agent LLC
If you sell consumer electronics on Amazon, you have probably hit a wall that looks like this: Amazon's listing form asks for "FCC Radio Frequency Emission & Authorization Status" with two options: FCC Certification with an FCC ID, or a Supplier's Declaration of Conformity (SDoC). In some cases Amazon flags an already-live listing and restricts it until you fill this in.
For most foreign sellers, this is the first time they have seen these terms. Picking the wrong one can block your listing while you chase documents you don't actually need. Here is the simple difference, what each one applies to, and the U.S.-party requirement that works very differently between the two.
The short answer
If your product has Wi-Fi, Bluetooth, cellular, or any other wireless transmitter, it needs FCC Certification and gets an FCC ID.
If your product has internal electronics (a microchip, charging circuit, motor, LED driver) but does not transmit wirelessly, it generally follows the SDoC procedure.
That covers the large majority of products on Amazon. Everything below is detail and edge cases.
What is an FCC ID?
An FCC ID is a unique identifier issued when your product completes FCC Certification through an FCC-recognized Telecommunication Certification Body (TCB).
Certification applies to products that intentionally generate radio-frequency energy, which the FCC calls "intentional radiators." Examples:
Wi-Fi routers, range extenders, mesh systems
Bluetooth speakers, earbuds, fitness trackers
Smart-home devices, smart bulbs, smart plugs
Cellular hotspots and modems
RFID readers and writers
Wireless garage-door openers, key fobs, baby monitors
An FCC ID looks like this: 2AFZZ-XMSF10G. It is assigned to the certification holder (the "grantee") and must be labeled on the product or shown via e-label.
If your product has an FCC ID, you enter it in the FCC ID field of Amazon's form and select that the product is FCC certified.
What is SDoC?
SDoC stands for Supplier's Declaration of Conformity (47 CFR 2.906). It is the FCC authorization procedure for most "unintentional radiators": products that contain electronics but don't intentionally transmit radio signals.
Under SDoC there is no FCC ID, no TCB review, no filing with the FCC, and no public database entry. The product must still be tested and shown to comply, and the test records must be kept and produced if the FCC asks for them.
Examples of SDoC products on Amazon:
Coffee makers, blenders, kitchen appliances
LED lamps, desk lights, ring lights
Hair dryers, electric toothbrushes, non-wireless beauty devices
USB chargers, power banks
Electric fans, humidifiers, non-smart air purifiers
Office gadgets, paper shredders, label makers
How to tell which one applies
1. Does the product transmit any wireless signal? Wi-Fi, Bluetooth, cellular, Zigbee, Z-Wave, RFID. If yes, it needs FCC Certification. If no, continue.
2. Does the product contain electronics? Microcontrollers, charging circuits, LED drivers, motor controllers, power supplies. If yes, it generally falls under SDoC. If it is purely mechanical, FCC rules likely don't apply.
3. Does your supplier actually have the right authorization? Many factories say a product is "FCC certified" when they only hold a test report. Ask for either the FCC ID number or the SDoC documentation and test report. Your test lab is the best party to confirm which procedure applies.
The U.S. party: two different roles
This is where most foreign sellers get confused, because the two pathways require two different kinds of U.S. party.
FCC Certification: U.S. Agent for Service of Process. A foreign applicant for Certification must designate a U.S. Agent for Service of Process under 47 CFR 2.911(d)(7). The agent receives legal process and official correspondence on the applicant's behalf and forwards it. The agent does not take on responsibility for the product's compliance. This is the role we provide.
SDoC: U.S. Responsible Party. SDoC does not use a U.S. Agent. Instead, the party responsible for the product's compliance must be located in the United States (47 CFR 2.909(b) and 2.1077). When the manufacturer is abroad, that is typically the U.S. importer. The Responsible Party is identified in the product's compliance information and is responsible for the product meeting FCC requirements. That is a compliance role, not a mail-forwarding role, and it is not a service we offer.
The contact fields Amazon shows for SDoC products (name, U.S. address, phone, email) correspond to that U.S. Responsible Party.
Common mistakes
Using a supplier's FCC ID. An FCC ID belongs to the certification holder. Using it for a product sold under your own brand without authorization from the grantee is a common listing problem.
Choosing FCC ID when you actually have SDoC. An FCC test report is not an FCC ID. If your product was not certified by a TCB, select SDoC.
Treating the SDoC contact as a mailbox. The U.S. party in the SDoC fields is the Responsible Party for the product's compliance. Listing a friend's address, a freight forwarder, or a mail-forwarding service does not make that party responsible, and it is one of the most common reasons listings get flagged.
FCC ID vs. SDoC, side by side
SDoC | FCC ID (Certification) | |
Applies to | Most non-wireless electronics | Intentional radiators (wireless) |
Rule | 47 CFR 2.906, Part 15 Subpart B | 47 CFR 2.907, Part 15 Subpart C/E |
FCC-issued ID? | No | Yes |
TCB review? | No (self-declaration) | Yes |
What Amazon wants | U.S. Responsible Party name, address, phone, email | The FCC ID |
U.S. party required | U.S. Responsible Party (47 CFR 2.909, 2.1077) | U.S. Agent for Service of Process (47 CFR 2.911(d)(7)) |
Designation letter? | No | Yes, signed by you and countersigned by the agent |
Our service | Not offered | $349/year flat |
Note: a wireless product often involves both: Certification for the radio and SDoC for the rest of the device. If Amazon asks for both, that is why.
What we do, and what we don't
We are: your U.S. Agent for Service of Process for FCC Certification applications under 47 CFR 2.911(d)(7). We prepare the designation letter, countersign it so it is ready for your TCB, and forward any FCC correspondence or legal process the same business day. Flat $349 per year.
We are not: your SDoC Responsible Party, your Importer of Record, your U.S. business entity, your testing lab, or your compliance consultant. We don't file with the FCC on your behalf, we don't put our name on your product, and we don't take responsibility for whether your device passed testing. Our address is for FCC regulatory correspondence only and can't appear on labels, packaging, customs documents, compliance information statements, or as a shipping address.
Most agent-of-record providers fold the Certification agent role into a consulting bundle priced in tiers, commonly from around $279 to well over $1,000. Once the lab and TCB work is done, the remaining annual requirement is a dependable U.S. agent of record, and we price it flat.
Next steps
If your product has an FCC ID (Certification) or you are filing with a TCB and need a U.S. Agent designation letter, get started here:
If your product follows SDoC, you need a U.S. Responsible Party, typically your U.S. importer or distributor. Your test lab can help with the SDoC documentation and compliance information.

FAQ
Amazon restricted my listing and asked for an FCC ID or SDoC. Can a U.S. agent fix that? For a Certification product, a U.S. Agent for Service of Process is required for the application, but you still need the FCC ID itself. For an SDoC product, what Amazon needs is your U.S. Responsible Party, which a U.S. Agent service does not replace.
Do I need an FCC ID or an SDoC? Wireless (Wi-Fi, Bluetooth, cellular, RF): almost always Certification with an FCC ID. Non-wireless electronics: generally SDoC. Your test lab can confirm.
Can I use my supplier's or factory's FCC ID? The FCC ID belongs to the certification holder. If you sell under your own brand, check with your supplier and test lab how the authorization covers your product.
Can your company be my SDoC contact? No. The SDoC contact is the U.S. Responsible Party for the product's compliance. That is a compliance role we do not take on. Our service covers the U.S. Agent for Service of Process role for FCC Certification.
Do I need an accredited lab for SDoC testing? The FCC requires SDoC products to be tested, but the testing lab does not need to be FCC-recognized or accredited. It must meet the applicable measurement requirements and keep the required facility description. Certification testing, by contrast, requires an FCC-recognized accredited lab.
Is your FCC U.S. Agent service a one-time fee? No. The designation must stay valid for as long as your product is on the market, so it renews yearly at the same flat rate.
