DotView.io Data Glossary

Clear definitions of FMCSA carrier data fields as used on DotView.io. Learn how raw data from the FMCSA export is interpreted and displayed to help users search, track, and understand motor carriers more effectively.

DOT Number

Export Field: DOT_NUMBER

The unique identifier assigned by the U.S. Department of Transportation to each registered motor carrier. This number is displayed identically in both the FMCSA export and the DotView.io user interface.

Legal Name

Export Field: LEGAL_NAME

The official legal business name of the motor carrier, as registered with the FMCSA. It is displayed as-is in the DotView.io interface, and is used for compliance and legal tracking purposes.

Display Name

Export Field: DISPLAY_LEGAL_NAME

The version of the carrier name shown in the DotView.io. While often identical to the FMCSA 'Legal Name', this may be normalized for better readability and user experience in search results or listings.

Export Field: PHY_STREET

The street address of the carrier’s main place of business. Comes directly from the FMCSA export and is shown in the site with no changes.

Export Field: PHY_CITY

The city in which the carrier’s main operations are physically located. This field is used as-is from FMCSA data in both site and export.

Physical State

Export Field: PHY_STATE

The state (e.g., TX, CA, NY) corresponding to the carrier’s physical address. Identical in both FMCSA export and the site.

Physical ZIP

Export Field: PHY_ZIP

The ZIP code for the carrier’s physical address. Exported directly from FMCSA and used unchanged in the site.

Physical Country

Export Field: PHY_COUNTRY

The country associated with the carrier’s physical location. While most entries are 'US', the field is displayed verbatim from FMCSA data.

The public contact phone number of the carrier. This is sourced from FMCSA records and displayed as-is in DotView.io.

The contact email address provided by the carrier in their MCS-150 form. This is pulled directly from FMCSA export and used in site with no formatting changes.

Carrier Status

Export Field: STATUS

Indicates whether the carrier is currently active or inactive according to FMCSA. DotView.io displays this status directly and may use badges or colors to enhance clarity, but the core status value is unmodified.

Fleet Size

Export Field: NBR_POWER_UNIT

Listed as 'NBR_POWER_UNIT' in the FMCSA export, this represents the number of power units (e.g., trucks, tractors) owned, leased, or operated by the carrier. In the DotView.io site, this field is labeled as 'Fleet Size' for clarity.

Drivers

Export Field: DRIVER_TOTAL

The number of drivers reported by the carrier in their MCS-150 form. Labeled as 'DRIVER_TOTAL' in the export, but simplified to 'Drivers' in the site to improve legibility.

Reported Mileage

Export Field: MCS150_MILEAGE

Mileage Report Year

Export Field: MCS150_MILEAGE_YEAR

The year associated with the mileage value from the MCS-150 form. Used in the site to help contextualize how recent the mileage data is.

Recent Mileage
