For U.S. addresses only, the Option.DualAddressLogic option controls whether ValidateAddress should return a street match or a PO Box/Rural Route/Highway Contract match when the address contains both street and PO Box/Rural Route/Highway Contract information in the same address line.
For example, given the following input address:
AddressLine1: 401 N Main St Apt 1 POB 1
City: Kemp
StateProvince: TX
PostalCode: 75143
ValidateAddress would return one of the following:
-
If
Option.DualAddressLogic is set to either N or P:
AddressLine1: PO Box 1
City: Kemp
StateProvince: TX
PostalCode: 75143-0001 -
If Option.DualAddressLogic is
set to S:
AddressLine1: 401 N Main St Apt 1
City: Kemp
StateProvince: TX
PostalCode: 75143-4806
The address data that is not used to standardize the address can be returned in one of two places:
-
AddressLine2—The
address information not used to standardize the address is returned in the
AddressLine2 field if you specify
Option.StandardAddressFormat=D. For more information, see Default Options. For example, if you choose to return a street
match for dual addresses,
AddressLine1: 401 N Main St Apt 1
AddressLine2: PO Box 1
City: Kemp
StateProvince: TX
PostalCode: 75143-0001 -
AdditionalInputData—If
you do not specify Option.StandardAddressFormat=D then the
address information not used to standardize the address is returned in the
AdditionalInputData field. For more information on this
option, see Default Options. For example, if you choose to return a street
match for dual addresses,
AddressLine1: 401 N Main St Apt 1
City: Kemp
StateProvince: TX
PostalCode: 75143-0001
AdditionalInputData: PO Box 1
Address information that is dropped can be retrieved by setting the Option.StandardAddressFormat option to D. For more information, see Default Options .
