Check the exact device before buying or using it
- Match the identifier, model, provider and software version against the current FMCSA registered and revoked lists. Similar product names can refer to different registrations.
- Check any removal notice for that device. Follow its instructions and specific deadline; an old directory entry does not establish current eligibility.
- Ask the provider to demonstrate supported inspection transfers, offline record access, corrections and malfunction handling for your vehicle and operating needs.
- Request a written quote separating hardware, installation, recurring service, connectivity and cancellation charges. Check how you can export records after ending the contract.
Registration is provider self-certification, not a government endorsement or a guarantee of service quality. Drivers and carriers still have recordkeeping duties. See carrier responsibilities and FMCSA’s ELD guidance.

What the Registration Covers
ELD registration means the provider self-certified compliance with the ELD technical specification — automatic driving-time capture, tamper resistance, a standard data file, and a supported roadside transfer method (this stored record lists Local (USB, Bluetooth), Telematic (Web Service, Email)). It does not mean FMCSA independently tested the device, which is exactly why the agency also maintains a revoked list and why you should verify before you buy.
