National Address Database Disclaimer

Before downloading, please read and accept the disclaimer below:

The National Address Database (NAD) is, with few exceptions, aggregated from state data, which is in turn aggregated from local data. While it is considered to be authoritative and every reasonable effort is made to ensure the accuracy and completeness of the data, the United States Department of Transportation (USDOT) makes no warranties, expressed or implied, concerning the accuracy, completeness or suitability of the data, and it should not be construed or used as a legal description.

In no event shall USDOT become liable to users of this data, or any other party, for any loss or damages, consequential or otherwise, including but not limited to time, money, or goodwill, arising from the use, operation or modification of the data.

In using this data, users further agree to indemnify, defend, and hold harmless USDOT for any and all liability of any nature arising out of or resulting from the lack of accuracy or correctness of the data, or the use of the data.

The states that partner with USDOT to provide data for the NAD do so willingly, with no obligation. Not every state that provides data to the NAD has complete coverage. As state address programs expand and mature, USDOT expects the coverage to expand as well.
