How we match

How ELDDecoded matches devices to their makers

Facts only. Every answer on this site is built from FMCSA's published electronic logging device (ELD) lists, and every grouping prints the evidence it stands on. This page is the whole method — there is no second, hidden method.

Where the facts come from

FMCSA publishes three lists: the devices makers have registered, the devices FMCSA has revoked, and the devices makers have withdrawn themselves. ELDDecoded keeps every published row — device name, model number, software version, ELD identifier, maker name, phone, and address, exactly as filed. The copy on this site is stamped: FMCSA lists as published November 1, 2026. When FMCSA's lists change, the copy is rebuilt and the stamp moves.

One thing the lists are not: an approval. Makers certify their own devices and register them; FMCSA keeps the register and says it endorses none of the devices on it. When a seller calls its device “FMCSA approved,” the accurate words are “FMCSA registered.”

How a checker answer is built

The checker answers for one model row at a time, because that is how FMCSA lists devices. A brand name is not a verdict: the same name can carry one model that is registered and another that FMCSA revoked, so the card always shows the model, the software version, and the ELD identifier next to the status. The maker block quotes the maker's name, phone, and address exactly as filed — including when the filing is sloppy, because that is what the public record says.

How makers are grouped into families

A family starts with the maker name as filed: every row filed under the same maker name belongs to that maker. Makers also file under spelling variants of their own names. When rows under two spellings carry the same phone number and the same street address, the spellings are grouped into one family, and the card names the other spelling and says why it was grouped. Nothing is grouped on a guess, and no family is built from an address alone — a shared registered-agent address, by itself, proves nothing about who sells a device.

How platform families are shown

Devices from different makers can share a piece of the filing itself: the same model, the same software build, or the same ELD identifier. When that happens across makers, the card shows a shared-platform block with the counts — how many device names and makers carry that platform, and how many of its rows are registered, revoked, or withdrawn. That is shared-platform evidence: it shows the devices run on a shared platform. It is not a claim that two devices are the same product, and this site never prints a claim about a maker's intent — only what the filings show.

A stronger layer is planned and deliberately not used yet: comparing the user manuals makers file with FMCSA, since two brands whose filed manuals are the same document would be firmer evidence than a shared model code. Until that comparison is verified, it plays no part in any answer.

The rules every maker is judged by

The rules above are the only rules, and they apply to every maker on the list in the same way — the biggest fleet brands and the smallest resellers alike. Statuses are FMCSA's. Dates are FMCSA's. Counts are counted from the rows, never typed in. If a card or a count is wrong, write to fwingeld@doogex.com and it will be checked against the published rows.

Who keeps this site free, and the promise that comes with it

ELDDecoded is kept free by FWING GROUP LLC, a company building its own electronic logging device. FWING is not on FMCSA's lists yet, so it has no card and no presence on this site beyond this page and the line in the footer. When FWING registers, it will appear in the checker under the identical rules as every other maker: one maker, one card, the same facts, nothing softened and nothing sharpened. A map that tilted its answers toward its own keeper would be worthless — so this one does not, and the method on this page is the proof anyone can check.

ELDDecoded is not part of FMCSA and is not affiliated with FMCSA or the U.S. Department of Transportation. FMCSA lists as published November 1, 2026.
