A USDOT number is the identification number FMCSA issues to a motor carrier so its operations and safety record can be tracked. O'Brien's Moving & Storage is U.S. DOT No. 30611, shown in the form that 49 CFR 375.207 requires. or call [775-359-6683](tel:+17753596683) [4.3 on Google · 71 reviews](https://obriensmoving-storage.com/reviews/) Family owned since 1941 [U.S. DOT No. 30611](https://obriensmoving-storage.com/about/licenses-and-authority/) If a mover works across state lines, FMCSA assigns it a number, and that number is the simplest way to find out who is behind a truck or a website. A short lookup on the public FMCSA record tells you a great deal. ## Where the number comes from Section 390.201 sets up the Unified Registration System. A carrier files an online application, FMCSA issues an inactive USDOT number, and activates it once the required filings are complete. The same section calls for biennial updates, and a missing update can lead to deactivation. The number identifies a company's operations for safety oversight and ties to the operating authority it obtains. ## How it must be shown Section 375.207 requires every advertisement, including a website, to carry the carrier's name as it appears on its USDOT record and the number only in the form U.S. DOT No. followed by the assigned number. That is why O'Brien's pages and trucks print U.S. DOT No. 30611 in that exact style. A number that is missing or shown another way is a signal to ask questions. ## How to check a mover FMCSA publishes a public company snapshot for each number. Enter the number or company name and look at three things: the legal name, whether the status is active, and whether the type of operation is household goods. Compare the legal name with the name on your estimate. There is a step by step walk-through on [how to check a mover's USDOT and MC number](https://obriensmoving-storage.com/guides/how-to-check-a-movers-usdot-number/). You can also review [O'Brien's licenses and authority](https://obriensmoving-storage.com/about/licenses-and-authority/). ## USDOT number and MC number are different - The USDOT number identifies the company with FMCSA - The MC number identifies operating authority for for-hire carriage - A household goods mover crossing state lines normally needs both O'Brien's holds both: U.S. DOT No. 30611 and MC-109375. ## Why the number matters to a customer The number is the thread that connects a company's name, its operating authority and its public record. Two companies can sound alike, but their numbers never match. When an advertisement shows a number, you can check it. When it shows no number at all, section 375.207 tells you something is missing, because every interstate household goods advertisement must carry the number. Putting the record next to the estimate before you sign is a calm, ordinary step that most careful customers take. ### Sources (checked October 18, 2026) - [eCFR, 49 CFR 390.201 (USDOT registration)](https://www.ecfr.gov/current/title-49/subtitle-B/chapter-III/subchapter-B/part-390/subpart-E/section-390.201) - [eCFR, 49 CFR 375.207 (advertisements)](https://www.ecfr.gov/current/title-49/subtitle-B/chapter-III/subchapter-B/part-375/subpart-B/subject-group-ECFR26b58a956b3b018/section-375.207) - [FMCSA, Your Rights and Responsibilities When You Move](https://www.fmcsa.dot.gov/sites/fmcsa.dot.gov/files/2023-10/FMCSA_R%26R_Handbook_Web_v1.pdf) ### Free in-home estimate - An O'Brien's estimator walks through your home - A written, itemized estimate - 10 free heavy-duty boxes, yours to keep [How our estimates work](https://obriensmoving-storage.com/how-our-estimates-work/) ### Visit or call the office 2277 Glendale Ave, Sparks, NV 89431 [775-359-6683](tel:+17753596683) | Monday to Friday | 8:00 am to 5:00 pm | | --- | --- | | Saturday and Sunday | Closed | [Get my free estimate](#estimate) ### Related - [Moving and storage glossary](https://obriensmoving-storage.com/glossary/) - [Mc number](https://obriensmoving-storage.com/glossary/mc-number/) - [How to check a mover's USDOT and MC number](https://obriensmoving-storage.com/guides/how-to-check-a-movers-usdot-number/) - [Licenses and operating authority: USDOT 30611, MC-109375, Nevada CPCN 1070](https://obriensmoving-storage.com/about/licenses-and-authority/) Moving glossary ## Read next - [Mc number](https://obriensmoving-storage.com/glossary/mc-number/) - [Cpcn](https://obriensmoving-storage.com/glossary/cpcn/) - [Household goods carrier](https://obriensmoving-storage.com/glossary/household-goods-carrier/) - [Moving broker](https://obriensmoving-storage.com/glossary/moving-broker/) - [Dish pack](https://obriensmoving-storage.com/glossary/dish-pack/) - [Crating](https://obriensmoving-storage.com/glossary/crating/) - [Vault storage](https://obriensmoving-storage.com/glossary/vault-storage/) - [Personally procured move](https://obriensmoving-storage.com/glossary/personally-procured-move/) Answers ## Questions people ask Still have a question?
