FCC ID Lookup: How to Decode Any FCC ID

Ever flipped a router over, or dug through a phone's settings menu, and found a jumble of letters and numbers next to "FCC ID"? Most people never look twice. But that code is a public record, and increasingly there's real money riding on what it says. In fiscal year 2024, US Customs and Border Protection seized more than 727,000 consumer electronics items suspected of carrying fake or unauthorised marks, worth over $125 million at retail price. An FCC ID isn't decoration. It's a searchable fact you can check for free in under two minutes, and this guide shows you exactly how.

What does an FCC ID mean?

An FCC ID is a unique identifier the Federal Communications Commission assigns when a radio-frequency device passes through equipment authorisation. It only applies to devices that intentionally or unintentionally emit RF energy: Wi-Fi routers, Bluetooth earbuds, garage door remotes, baby monitors, drones, and thousands of other gadgets. A plain kettle or a dumb lamp doesn't need one, because it doesn't broadcast anything.

Most devices with an FCC ID went through Certification, the strictest of the FCC's authorisation routes. An accredited lab tests the product, and a Telecommunication Certification Body (TCB), a third party recognised by the FCC, reviews the results and grants the authorisation. Only then does the FCC ID get issued and attached to that specific model. Some radio devices instead go through a lighter self-declared route with no FCC ID at all; our FCC certification vs SDoC piece covers which products land where, and the FCC's own rules for intentional radiators and unintentional radiators set out the technical split.

The short version: if you can find an FCC ID on a product, someone tested that exact model and a named organisation put their name behind it. That's what a lookup lets you verify.

How do you find the FCC ID on a device?

Manufacturers have to display the FCC ID somewhere a user can reasonably find it, but "somewhere" varies a lot by product.

• On most home electronics (routers, smart speakers, set-top boxes), it's printed directly on a label stuck to the underside or back panel, often alongside the model number, serial number and power rating.
• On phones, tablets and other devices with a battery compartment, it's sometimes printed inside, under the battery or SIM tray, rather than on the outer casing.
• On very small products, such as earbuds or key fobs, there may not be room for a legible label at all. In that case the code often moves to the packaging or the printed insert instead.
• On anything with its own screen, manufacturers can use an "electronic label" instead of a sticker. Under the FCC's e-labelling rules, the information has to be reachable in no more than three menu steps, typically something like Settings, then About, then Regulatory or Certification information.

If you genuinely can't find it anywhere, on the device, in the box, in the manual, or in a software menu, that's worth noting in itself. It doesn't automatically mean the product is unauthorised, but it's a reasonable prompt to ask the seller directly before you rely on the claim.

Decoding the code: grantee and product numbers

Once you've found it, an FCC ID isn't a random string. It's built from two parts joined together: a grantee code, which the FCC permanently assigns to a company, and a product code, which that company assigns itself to identify one specific model.

The grantee code's length depends on how it starts, which is worth knowing so you can tell where one part ends and the other begins.

Grantee codes never use the digits 1 or 0, because they're too easy to mistake for the letters I and O on a small printed label. The product code that follows is chosen by the grantee itself: any mix of capital letters, numbers and hyphens, with the combined length of grantee code plus product code capped at 14 characters in total. So an FCC ID reading "2AABC-WIFI01" splits into grantee code 2AABC and product code WIFI01; one reading "XYZ123456789" splits into grantee code XYZ and product code 123456789. Once you can mentally split the two halves, the lookup itself is straightforward.

How does an FCC ID lookup actually work?

The FCC runs the authoritative record at its OET Equipment Authorization Search, a free public tool with no login required.

The basic search asks for the grantee code and product code separately, which is exactly why splitting the FCC ID matters. Type the grantee code into the first box and the product code into the second, then run the search. If you only have the combined code and aren't sure where the split falls, the FCC's own FCC ID Search guidance explains the grantee-code length rule the same way we've laid out above, and a bit of trial and error with the split usually gets you there. There's also an advanced search on the same tool that lets you search by applicant name, date range or product description instead, handy if the printed code is smudged or partly missing.

Third-party mirrors of the database, built on top of the FCC's public filings, often present the same records with a friendlier search box and better photo galleries. They can be a good starting point, but treat the FCC's own database as the source of truth if anything looks inconsistent.

What the database results actually tell you

A successful search takes you to a grant page, and this is where the lookup earns its keep. For a Certification-class grant, you'll typically see the grantee's registered legal name and address, the date the grant was issued, and a set of filed exhibits: the test lab's report, internal and external photos of the actual tested unit, a copy of the user manual, and an RF exposure statement.

That's a lot more than a sticker can tell you on its own. It confirms who really stands behind the product (which isn't always the brand printed on the box), what the tested unit actually looked like inside, and roughly when testing happened. If the grantee name on the record has nothing to do with the brand you bought, or the product photos show a device that looks nothing like what's in your hands, that's a genuine red flag rather than a technicality.

Why bother? Real reasons to run a lookup

Say you're sourcing a wireless dash cam from a marketplace supplier who insists it's "FCC certified" and quotes an FCC ID in their product sheet. Before you commit to a container of 2,000 units, a two-minute lookup tells you whether that ID actually belongs to a dash cam, whether it belongs to that supplier's factory at all, or whether it was borrowed from an unrelated product to make the listing look credible. Catching that before the goods are on a ship is a lot cheaper than catching it at the border.

That scenario isn't hypothetical in the aggregate. Consumer electronics were the third most-seized category of counterfeit goods entering the US, behind only handbags and pharmaceuticals, in CBP's fiscal year 2024 seizure statistics. Some of that involves outright counterfeit branding, but mislabelled or borrowed certification claims sit in the same enforcement territory: importing RF equipment without valid authorisation is a compliance failure regardless of whether the electronics inside are otherwise fine.

It isn't only the product that can be untrustworthy, either. The FCC has recently tightened its own rules on which labs are allowed to issue these grants in the first place. As FCC Chairman Brendan Carr put it when announcing new restrictions on foreign-controlled test labs, "these labs provide a gateway into the U.S. telecommunications infrastructure. And it is not hard to imagine that an unreliable lab, one beholden to a foreign adversary, could sign off on insecure gear entering the U.S. market," a comment made in the FCC's statement banning certain foreign-linked test labs from the authorisation process. A lookup that shows you the grantee, the TCB and the test lab behind a device gives you something concrete to check against that kind of concern, rather than just trusting the sticker.

The same logic applies if you're reselling secondhand electronics, importing a product line for the first time, or simply reassuring yourself before you plug something into your home network. Our guide to importing electronics from China covers the wider import paperwork picture if sourcing is your main concern.

FCC ID vs CE marking: same idea, different system

If you sell into both the US and Europe, don't assume one authorisation covers the other. An FCC ID confirms US radio-frequency authorisation only. It has no bearing on whether a product meets EU requirements, and a CE mark has no bearing on FCC compliance. The two systems test against different technical limits, use different bodies, and keep entirely separate public records. If you're weighing up what a CE mark actually requires alongside your FCC obligations, our piece on CE marking requirements walks through that side in plain terms.

Running an FCC ID lookup takes less time than reading this paragraph. Split the code, paste the two halves into the FCC's search tool, and see who's actually behind the product in your hands. If you're building or importing hardware that needs both US and EU paperwork sorted before launch, our requirements page is a good next stop for mapping out what applies to your specific product.
