MCS-150 Filing Services
USDOT number maintenance and MCS-150 biennial update filing—deadline tracking, data verification, electronic submission, and confirmation documentation that prevents operating authority deactivation and keeps your carrier registration current.
Federal regulations require interstate motor carriers to update their MCS-150 registration information every 24 months. Missing this deadline triggers penalties and can result in deactivation of your USDOT number and operating authority—preventing legal operation until the update is filed and any penalties resolved. Many carriers discover their authority has been deactivated only when a driver is stopped at a roadside inspection or a shipper runs a carrier qualification check.
DSC eliminates this risk with comprehensive MCS-150 filing services: we track your biennial update deadline, verify your registration data for accuracy, file the update electronically with FMCSA, and provide confirmation documentation for your records. Our proactive reminders at 90, 60, and 30 days before your deadline ensure you never face authority deactivation from a missed filing. For carriers needing expedited service, we offer rush processing to resolve urgent situations quickly. Keep your USDOT number active and your authority intact with systematic MCS-150 management.

Frequently Asked Questions
Your MCS-150 must be updated every 24 months based on the last digit of your USDOT number and your filing month. FMCSA provides a schedule, but many carriers lose track of their specific deadline. DSC tracks your deadline and provides advance reminders so you never miss an update.
Missing your biennial update deadline results in USDOT number deactivation. You cannot legally operate with a deactivated number—drivers may be placed out of service at roadside inspections, and shippers will see your authority as inactive when running carrier qualification checks. Filing the overdue update reactivates your number, but delays can disrupt operations significantly.
Yes. We gather the required information, verify data accuracy against your current operations, and file the update electronically with FMCSA on your behalf. You receive confirmation documentation and updated deadline tracking for your next biennial filing.
