ELD certification means the provider vouches, not FMCSA
A "certified" ELD has not been tested or approved by FMCSA. Its provider tested it, certified it, and registered it, and FMCSA can take it off the list.

ELD certification in numbers
ELD certification means the device's provider, not FMCSA, tested the device and certified that it meets the technical specifications in 49 CFR Part 395, then registered it with FMCSA. Carriers must use a device from that registered list, and FMCSA can remove devices that fall short.
Carriers often read "certified" on an ELD sales page as a government guarantee. It isn't. It means the vendor made a promise, and if the promise turns out to be wrong, the carrier is the one who has to replace the device.
I lead operations at Simplex, and I treat an ELD purchase like any vendor decision in a compliance system: verify the claim against the source, record what you checked, and check it again on a schedule.

Key takeaways
Certification is self-certification
The provider tests each device with a procedure of its choosing and certifies it. FMCSA does not test or endorse devices before listing them.
The registered list is the legal test
Under 49 CFR 395.22(a), a carrier required to use an ELD may use only a device on FMCSA's registered list.
Certification covers one model and version
Each listing names a model, a software version, and a six-character ELD identifier that also appears on the device's roadside display.
FMCSA can revoke a certified ELD
After notice and a chance to fix the problem, FMCSA removes the device. Carriers then get up to 60 days to replace it.
Nothing changed for pre-2000 trucks
The ELD specifications have not been amended since 2023, and vehicles built before model year 2000 can still use paper logs.

What does ELD certification mean?
ELD certification means the device's provider has certified that it meets FMCSA's technical specifications and has registered it with FMCSA, so it appears on the agency's list. The provider does the testing. FMCSA does not.
An ELD, or electronic logging device, is a device or technology that automatically records a driver's driving time and supports accurate hours-of-service records, as defined in 49 CFR 395.2. The specifications it must meet are in Appendix A to Subpart B of Part 395.
Who certifies an ELD?
- The provider registers. It opens an account with FMCSA and names the person authorized to certify its devices.
- The provider tests and certifies. It certifies that each model and version has been sufficiently tested, using any test procedure it chooses.
- FMCSA lists the device. The registered list states that the devices are self-certified and that FMCSA does not endorse any ELD.
- FMCSA investigates problems. It tests a device with its own compliance test procedure only when it suspects the device does not conform.
White-label brands may rely on the certification of the company that built the device, so the name on the box is not always the name on the list.
Your side of the rule is short. Under 49 CFR 395.22(a), a carrier required to use an ELD may use only a device on FMCSA's registered list. Our complete guide to electronic logging devices covers the rest of the ELD rule.
What does a provider certify when it lists an ELD?
The provider certifies one specific model and software version, not a brand. To complete online certification it must disclose 10 items, and FMCSA publishes most of them on the list.
| Disclosure | Why it matters to you |
|---|---|
| Product name, model number, software version | Certification covers that exact version. Match all three to what you are buying. |
| ELD identifier | A six-character code that also appears on the roadside display and printout, so you can check the unit in your truck against the list. |
| Data transfer methods and instructions | Shows whether the device uses telematics transfer (web services and email) or local transfer (USB and Bluetooth). |
| Summary of ELD malfunctions | Shows which malfunctions the device detects and reports. |
| Certifying statement | Describes how the provider says it tested the device. |
| User's manual | Downloadable from the list, so you can read it before you buy. |
What the specifications require
Appendix A runs to dozens of pages. A few requirements shape what a device can do in your fleet:
- Engine link. On a model year 2000 or later vehicle with an engine control module (ECM), the ELD must link to the ECM for engine power, motion, miles, and engine hours.
- Automatic driving status. The ELD records driving whenever the vehicle moves, unless the driver first sets personal conveyance or yard moves.
- Roadside transfer. On demand, the ELD produces the current 24-hour period and the previous 7 days, and shows them on a display or printout.
- Retention. The ELD keeps records for at least 6 months.
Certification is not frozen in time either. Providers must keep their registration current and update it for major changes, and each provider decides whether a firmware update is significant enough to change its listing.
How does FMCSA remove a certified ELD?
Through a notice process in section 5.4 of Appendix A. The provider gets a chance to respond and fix the problem before the device comes off the list:
- FMCSA sends the provider a written notice with its reasons and the corrective action required.
- The provider has 30 days to respond. With no response, the device is removed.
- If the provider responds, FMCSA withdraws, changes, or affirms the notice. The provider then has 60 days to take any required action, or the device is removed.
- After a removal, the provider has 30 days to request an administrative review.
FMCSA does not publicize ELD investigations, so the removal is usually the first public sign of trouble. As of September 24, 2026, FMCSA's revoked list shows 132 devices removed by FMCSA, plus 254 marked "Self Revoked" by their own providers.
What happens when your ELD is revoked?
FMCSA gives carriers up to 60 days. Stop using the revoked device, record hours on paper logs or logging software, and replace it with a registered ELD before the deadline. After that, drivers still using it, or improperly using paper logs, are cited under 49 CFR 395.8(a)(1) and placed out of service.
The most recent removal, on August 6, 2026, covered five devices that must be replaced before October 6, 2026. Our ELD mandate update tracks each removal this year.
Did ELD certification rules change in 2025?
No. The eCFR's version history shows Appendix A, the ELD technical specifications, has not been amended since November 2023. Nothing in 2025 changed how devices are certified.
An earlier version of this article said new 2025 specifications require ELDs in vehicles built before 2000. That was wrong. Under 49 CFR 395.8, a vehicle manufactured before model year 2000, as shown by the VIN on its registration, may still use paper logs.
The certification model could change someday. In its 2022 ELD revisions notice, FMCSA asked whether it should establish its own certification process for ELDs. It has not proposed one; our update on the ELD revisions tracks where that stands.
What should you check before buying an ELD?
Each check takes minutes, and each one ties the vendor's claim back to FMCSA's own records.
Step 1: Find the exact listing
Search the registered ELD list for the product name, model number, and software version you are being sold. For phone and tablet apps, the provider certifies the software and lists the compatible operating systems.
Step 2: Search the revoked list
Search the Revoked ELDs tab by product name and ELD identifier. FMCSA relists a device if its provider fixes the deficiencies, so go by the device's current status, not an old news story.
Step 3: Test a data transfer
Read the listed transfer method, then have the vendor walk a driver through a transfer. FMCSA's buying tips warn that many portable devices rely on cellular coverage, which matters if you run remote routes.
Step 4: Confirm it fits your trucks
On model year 2000 and later trucks with an ECM, the device must link to the engine. If you also run older trucks, decide whether they will use the ELD or stay on paper under the pre-2000 exemption.
Step 5: Match the device to the list after installation
The roadside display and printout show the ELD identifier and the provider. Compare them with the listing after installation and after software updates.
Step 6: Recheck on a schedule
Put a monthly list check on one person's calendar, and sign that person up for FMCSA's ELD email updates, which announce removals. Our ELD solutions and DOT safety compliance team can help with both the device and the routine.
