Address Ranges County-based Relationship File


The term “address range” refers to the collection of all possible structure numbers from the first structure number to the last structure number and all numbers of a specified parity in between, along an edge side relative to the direction in which the edge is coded.  The TIGER/Line Shapefiles contain potential address ranges, not individual addresses.  Potential ranges include the full range of possible structure numbers even though the actual structures might not exist.


The address ranges relationship file contains the attributes of each address range.  Each address range applies to a single edge side and has a unique address range identifier (ARID) value.  The edge to which an address range applies can be determined by linking the address range to the All Lines shapefile using the permanent edge identifier (TLID) attribute.  Multiple address ranges can apply to the same edge because addresses with different number sequences (e.g., 101, 103, 1622, 1624…) or non-numeric characters (e.g., N101, N103, S099, S97) can appear along that edge.  Note that the most inclusive address range associated with each side of a street edge appears in the All Lines shapefile.
