National Address Database (NAD) Text File

The Address Points from National Address Database dataset was compiled on September 30, 2026 by the US Department of Transportation. The National Address Database (NAD) is a spatial database containing address data, point location coordinates, jurisdictions, record-level metadata and other supporting data for addressable locations including structures, some sub-units within those structures, and landmarks as included in the aggregated datasets from providers included therein.

Technical Note: Record Ordering and Object IDs Please Note: The records in this flat text file are structured in their optimized physical database order, rather than numerical sequence by OID_ (Object ID). Because the National Address Database leverages highly efficient spatial indexing and bit-packing compression algorithms before export, geographically clustered records (such as specific states or counties) are grouped together on disk.

All OID_ values remain perfectly unique across the entire dataset, but they will appear out of chronological order when reading the file sequentially. If your integration workflow requires a strict numerical sequence, you can safely sort the dataset by the OID_ column upon ingestion.
