| Data point | Data Description | Basic | Premium | Premium+ |

| SmartyKey EXT | Identifies singular locations with multiple addresses. For example, if an address has changed over time (e.g., renumbered, renamed, or reformatted), SmartyKey EXT recognizes that the old and new addresses refer to the same underlying location | |||
| First line | Contains the delivery line (street address). This can include the composition of a primary number, street name, suffix, predirection, postdirection, secondary designator, and secondary number. | |||
