Starting a trucking operation? You need a USDOT number before you can run — and a rejected or incorrect filing means weeks of delay. Simplex files your USDOT registration for you, start to finish, so you're on the road faster.
Carriers of every size rely on us to stay compliant and rolling.
A quarter-century through every FMCSA rule change.
Filings, records, monitoring, and audits — all under one roof.
Every angle of compliance watched, so nothing slips.
From a brand-new USDOT number to updates and reactivations, we file your federal registration accurately and get you operating.
Your USDOT number filed correctly the first time — no rejected applications.
New to trucking? We guide the full registration from the ground up.
Carrier info, address, or fleet changes updated on your USDOT record.
Inactive or deactivated number reactivated and back in good standing.
The right registration for how and where you operate.
We verify your number, status, and record are correct and active.
A USDOT application filed wrong can cost you weeks before you can legally run. For 25 years we've registered carriers correctly the first time — one specialist handling your filing start to finish.
We track deadlines, scores, and violations continuously — not just at renewal.
One specialist who knows your operation by name, start to finish.
Plain-English answers on exactly what you need, and when.
We catch issues early, before they reach an audit or an Out-of-Service order.
Every document and due date kept in order and ready when you need it.
We stay with you all year — for every requirement, not just audits.
"I've been using Simplex for almost a year now, and I'm very happy with the service they've provided. A month ago, I had my audit, and I couldn't have asked for better help than what Ms. Catherine Games provided. She helped me understand the entire process and assisted me in gathering all the information requested by the officer. From day one, she was very kind until the completion of my audit, which was a success."
"Simplex has been taking care of my company for quite some time now and they're a dream to work with. They do everything for you so you're not worried about if your company is missing something and they're very thorough. In the audit process, Hansey Reyes is the best! She makes sure all documents are uploaded on time and she's very knowledgeable about it so she can offer good advice in the event you have problems in any of the areas DOT looks at."
"Simplex have been very beneficial to our company and we appreciate everything they have done to maintain us in compliance all the time! Special thanks to SAM Christianne Espinoza and Lilian Medina, as they have been the key to our success!"
