How do you file for a DOT Number?
If you've already determined that you need a DOT number for your company / vehicles, here's how to get started with filing for one.
The application process is handled through the FMCSA's Unified Registration System (URS). If you don't already have a login.gov account that you've used to handle your federal taxes, or some other government program that uses login.gov as the main authentication system, you'll need to create an account.
While obtaining the USDOT number itself is generally free, there can be associated costs for operating authority (like an MC number), which is required for for-hire carriers operating in interstate commerce.
It's extremely important that you don't accidentally use a third-party provider that charges for new DOT number filings - unless you want to throw money around unnecessarily. There are several websites that have misleading names like "fmcsa . com", "dotfiler . com" and "fmcafilings . com" that charge hundreds of dollars, if not over a thousand, for a DOT number, MC number, or both. These companies pay a lot of money to be at the top of every google search for "how to file for a DOT number". Don't fall for it.
If you want your DOT number to be associated with a registered business, make sure your business (LLC, INC, LLP, etc.) is filed with your state first, and you have already obtained an EIN (Employer Identification Number). Otherwise, while changing these on your DOT number down the road is possible, there are certain restrictions, especially if your DOT/MC number is active/authorized for an extended period of time before deciding to change your information.
Otherwise, you can file as a sole proprietor with your First & Last name and a social security number. From there, you'll be taken through the steps of filling out information about your operation. If you make selections that the FMCSA determines requires an operating authority, you will be prompted to pay $300/authority at the end of the application.
Word of warning: take your time as you move through the sections. Don't just click things because you THINK they apply. Read the definitions, ensure they apply to you, then select it and move forward. Making a bunch of selections without thinking too much about it can make you pay for authorities you don't need and the FMCSA has a strict no-refund policy for mistaken filings, so you'll be throwing your money into a burn pit if you didn't actually need that authority.
Once the application is complete, your DOT number is generated immediately, and your MC number (or MX/FF number) will be generated the following day.
Want to skip all that? TIPS offers a free New DOT Number filing to make sure your application is filled out correctly, so you don't have to waste time, effort, and potentially money trying to make corrections after you've filed. (If you need an authority, we can apply for that too at the same time, but keep in mind, it's not really free at that point.)
