Dual Addresses

GeocodeUSAddress can process input that contains two addresses for the same record on the same address line. For example, GeocodeUSAddress can process the following input address:

3138 HWY 371
PO BOX 120
PRESCOTT AR 71857

GeocodeUSAddress does not recognize dual addresses where the two addresses are both street addresses. For example, GeocodeUSAddress does NOT recognize 135 Main St 4750 Walnut St Ste 200. GeocodeUSAddress does recognize dual addresses where the two addresses are the same type of address but are not street addresses. For example, GeocodeUSAddress does recognize PO BOX 12 PO BOX 2000.

After GeocodeUSAddress parses the dual address, it searches for a match. GeocodeUSAddress determines which address has preference for a match based on the processing mode. In CASS mode, GeocodeUSAddress ignores the prefer PO Box and prefer street options, and attempts to find a match based on the following order: PO Box, Street, Rural Route, and General Delivery. In Relaxed mode, GeocodeUSAddress recognizes the Address Preference (AddressPreference) input option.
