What Are the Most Common UCR Filing Mistakes

At first glance, filling in for Unified Carrier Registration (UCR) might appear to be like a routine task, just another box to check in the endless list of compliance rules. In reality, each year, due to minor mistakes, hundreds of carriers, fleet owners and brokers face issues that lead to serious consequences within their business. In the trucking industry, compliance is of utmost priority; just a small overlooked detail or missed payment can lead to costly fines, halt operation, and even put your DOT authority under risk.
In this blog, we will bring to your attention the most common UCR filing mistakes that the representatives of the trucking industry made and tell you how to avoid them so your business stays compliant, protected, and running without interruption.

Missing the UCR Filing Deadline

One of the most common and most serious mistakes that carriers make is not meeting the UCR filing deadline. UCR registration opens on October 1 and lasts through December 31 of the previous calendar year. Therefore, carriers have enough time for preparing and meeting the deadlines. Missing this deadline can lead to fines and may also cause your vehicle to be flagged during roadside inspections, resulting in avoidable compliance problems and added stress. To avoid such unpleasant consequences, we recommend that you set up reminders once the window opens or trust this process to a trustworthy filling service. In this case you can be sure that everything within your trucking business goes smoothly.

Providing Incomplete or Outdated Company Information

One of the main reasons behind why UCR filings can be rejected or flagged is inaccurate or outdated company information. Try to make sure that your carrier name, DOT number, and business address are correctly matched to the records on file with the FMCSA; otherwise, your submission may be delayed or declined. So, before filing, make sure that you gather all the necessary information. Additionally, log in to your FMCSA account to make sure that your company name, business address, and DOT number are accurate and up to date. If there is a need for changes, submit an MCS-150 update first to ensure your records match. Taking the above-mentioned steps in advance can help you prevent filing issues and keep your UCR registration smooth and compliant.

Reporting the Wrong Number of Vehicles

Providing an invalid vehicle number is one of the most common and major mistakes because UCR registration fees are based on the number of commercial motor vehicles in your fleet. So, underreporting may lead to audits and possible penalties, whereas overreporting means that you have to pay more than you should. So, in order to stay compliant and avoid unnecessary costs, thoroughly review your fleet records before filing. Count only the active power units used in interstate commerce and exclude trailers, leased units, or inactive vehicles that aren’t currently operating. Remember that taking a few extra minutes to verify this information can save time and money.

Filing Under the Wrong Business Type

When running your operation, one common UCR filing difficulty is registering under the wrong business type. It’s common for brokers, freight forwarders, or leasing companies to register as motor carriers by mistake or vice versa, causing them to pay the wrong fee or face compliance problems. So, before submitting your registration, first try to understand your business classification. In case you are a broker or leasing company without vehicles, your filing category will differ from that of a motor carrier operating commercial trucks. By verifying this detail ahead of time, you may avoid any needless expenses and problems with compliance.

Filing Through Unofficial or Scam Websites

Unfortunately, when one is looking online for UCR filing help, there is a big chance of encountering fake or unofficial websites. Usually, these sites charge extra fees or fail to file registration at all. To avoid similar issues, always use the official UCR registration portal, or make sure that any third-party services are legitimate by checking reviews and confirming their authenticity before paying.
