Kentucky - KYU #. Call 231-947-5573

We are licensed and registered with the state of Kentucky to obtain KYU numbers for motor carriers.

****Special Notice****

You are now required to complete the UCR registration for the year in which you first obtained your USDOT number regardless of when your MC number became or will become active. As an example, you filed for and obtained your new USDOT & MC numbers on December 31, 2014. Even though you did not start operations until 2015, you must also complete the 2014 UCR because your USDOT number was issued in 2014. This is a policy change from previous years and there are no exceptions.

It will take 1-2 days to upload new UCR registration(s). This may cause a delay in obtaining your KYU if you just completed your UCR registration.

If you travel through the state of Kentucky, in a commercial vehicle (private and/or for-hire), with a registered GVWR of 60,000 lbs or more, you will need a KYU # or you will need to buy a temporary KYU permit. Currently, a ten day temporary permit will cost you approximately $46.00 and can be obtained directly from KY.

The KYU number issued by the Kentucky Transportation Cabinet is a permanent weight distance tax license, no yearly renewals. Kentucky does require that you maintain a vehicle inventory for your KYU number. All trucks will need to be listed on your KYU number inventory and must be added or deleted as your trucks change.

KYU Number       

                   $ 40.00                

Your MC number must be active to obtain a KYU #.

To obtain your KYU #, you must have the following:

1. UCR registration completed for all years of operation, past and present.
2. USDOT number must be active.
3. Proof of insurance must be on file with the FMCSA if you have an MC# and your MC # must be active.


This application is for a new KYU number. If you previously had a KYU number, you will need to call the Kentucky tax division at 502-564-4150 to reinstate your old KYU number. If you need a 10 day temporary permit, please call 502-564-4127.

KYU numbers are issued by the Kentucky Transportation Cabinet between the hours of 8:00 am and 4:30 pm EST, Mon-Fri.

If we receive your application by 2:00 PM EST, Mon-Fri, we can usually have your KYU number the same day. Kentucky states that it can take up to 48 hours for your KYU number to be issued. This can and does happen. Our experience is it will takes anywhere from less than 3 hours to 24 hours. Times stated above are not guaranteed, delays are possible.
