Can your DOT number be deactivated?
By the DOT Compliance Partner team · May 11, 2026 · 3 min read
Yes, a USDOT number can be marked inactive or deactivated. The most common cause is a missed MCS-150 biennial update — FMCSA will flag a registration as inactive if the required update hasn't been filed on schedule.
Other reasons a DOT number goes inactive
- No MCS-150 filed within the required update window
- Voluntarily requesting deactivation
- FMCSA administrative action
- Operating authority being revoked (which can indirectly affect the DOT registration status)
What shows in SAFER when a number is inactive
An inactive USDOT number shows that status publicly in FMCSA's SAFER system. Shippers, load boards, and roadside enforcement officers can see this. Many carriers and brokers won't work with a carrier whose DOT number shows inactive.
How to reactivate it
In most cases, filing an overdue MCS-150 will bring the registration back to active status. The filing is free and can be done directly through the FMCSA Portal. Processing time varies but usually takes a few business days.
If the deactivation is due to something other than a missed MCS-150, the fix depends on the cause. That's when it's worth getting a compliance professional involved to diagnose and resolve it quickly.
