What Is an FCC ID, and Why Should Radio Operators Know About It?

If you’ve recently browsed online marketplaces for amateur radio equipment, you may have noticed discussions about new FCC requirements for displaying FCC identification numbers on products offered for sale.

The changes have raised questions among amateur radio operators, particularly those buying and selling equipment through online marketplaces such as eBay.

While the requirements have created some confusion, they also provide an opportunity to learn about a useful resource: the FCC Equipment Authorization Database.

What Is an FCC ID?

An FCC ID is a unique identifier assigned to a device that has received equipment certification under Federal Communications Commission rules.

Many electronic devices that transmit radio signals must be certified before they can legally be marketed in the United States. Examples include:

GMRS, FRS, and CB radios
Many commercial and public safety two-way radios
Wi-Fi and Bluetooth devices
Wireless networking equipment
Cell phones and other radio-frequency devices

An FCC ID has two parts: a grantee code (the first three or five characters), which identifies the company responsible for the certification, and a product code (the remaining characters), which identifies the equipment.

It is different from a radio’s model number or serial number, and from an amateur operator’s call sign. Equipment certification is also separate from your amateur radio license: certification applies to a piece of equipment, while your license authorizes you, the operator.

What Changed in October 2026?

The FCC adopted new rules on July 22, 2026, and published them in the Federal Register on September 11, 2026. Among other changes, they strengthen the FCC’s equipment marketing rules (47 CFR § 2.803) for online marketplaces, including a requirement that marketplaces display the FCC ID of a certified radio-frequency device at the online point of sale.

The rules took effect October 13, 2026. The FCC ID display requirement has later compliance dates:

March 1, 2027: online marketplaces that sell devices themselves, or that have physical access to or take title to a third-party seller’s device.
June 1, 2027: online marketplaces that list a third-party seller’s device without handling it or taking title. These marketplaces must check that the FCC ID matches a valid entry in the FCC database and have the seller certify that it is accurate.

The display requirement does not apply to:

Listings for used devices
Listings published before October 13, 2026, unless they are later amended, updated, or republished
Listings by sellers who are not “high-volume third-party sellers” as defined in the federal INFORM Consumers Act

These exemptions cover only the display of an FCC ID. The existing rule that equipment requiring certification may not be marketed without it still applies to everyone.

Importantly, these requirements concern equipment subject to FCC certification, not every electronic device or amateur radio.

What About Amateur Radio Equipment?

There is an important distinction for amateur radio operators.

Equipment designed to transmit only within amateur radio frequency allocations generally does not require FCC equipment certification.

A notable exception is external RF power amplifiers: commercially manufactured or imported amplifiers for amateur use must be certified (47 CFR § 97.315). Some amateur products also contain separately certified wireless components, such as Wi-Fi or Bluetooth modules.

Following questions from the amateur radio community, ARRL reported on October 16, 2026 that eBay clarified its policy: equipment operating only on amateur radio frequencies does not need an FCC ID to be listed. eBay also said that two-way VHF and UHF radios able to operate outside the amateur bands cannot be sold there without FCC certification. Sellers whose ham-only listings are restricted by mistake can contact eBay to request a review. This is eBay’s policy; other marketplaces may handle amateur equipment differently.

An important reminder: an FCC ID does not authorize a radio to operate on every frequency it can transmit on, and it does not license the person using it. Operators must follow the rules of the radio service they are using and hold any license that service requires.

How to Look Up an FCC ID

One particularly useful feature of FCC equipment certification is that much of its supporting documentation is publicly available. You can search it for free in the FCC’s Equipment Authorization Search.

Open the FCC Equipment Authorization Search

Find the FCC ID. Look on the radio’s label, packaging, manual, or regulatory information screen. For online purchases, check the product listing or ask the seller.
Search the FCC database. Open the FCC search page. Enter the first three or five characters of the FCC ID in the Grantee Code field and the remaining characters in the Product Code field. If you are not sure where the grantee code ends, try three characters first, then five.
Identify the equipment. Confirm that the applicant name, equipment description, and certification correspond to the equipment you’re researching.
Review the documentation. Depending on the equipment, publicly available information may include:
- Certification grants
- Test reports
- Operating-frequency information
- Transmitter power information
- User manuals
- External photographs
- Internal photographs and technical descriptions

Some documents, such as schematics, may be kept confidential at the manufacturer’s request.

Why Is This Useful to Radio Operators?

Imagine finding an inexpensive handheld transceiver advertised as suitable for amateur radio, GMRS, and commercial communications.

Before purchasing, you could look up its FCC ID to investigate:

Frequency authorization: Which frequency ranges are covered by the certification?
Power and emissions: What transmitter characteristics were included in the authorization?
Regulatory classification: Under which FCC rules was the equipment certified? For example, Part 95 covers GMRS and Part 90 covers commercial land mobile radio.
Product identification: Does the certification match the radio being advertised?

This can be particularly helpful when comparing unfamiliar radio brands or equipment advertised for multiple radio services.

However, an FCC ID is not a guarantee of product quality, cybersecurity, or legal operation in every configuration. Nor does a valid certification prove that an individual unit is genuine or unmodified.

Not every lawful electronic device has an FCC ID. Some equipment uses other compliance procedures, such as the Supplier’s Declaration of Conformity, or is exempt from equipment authorization.

A Useful Tool for Every Radio Operator

Whether you’re purchasing your first handheld radio, evaluating a GMRS transceiver, or researching an unfamiliar wireless device, understanding FCC IDs gives you another way to make informed purchasing decisions.

The new marketplace requirements may take some adjustment for online sellers, but greater visibility into equipment certification can be useful for consumers.

We encourage club members to explore the FCC database the next time they’re researching equipment. You may be surprised by how much technical information is publicly available.
