About Dual Address Logic

For U.S. addresses only, the Dual address logic option controls whether Validate Address 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.

Note: The Dual address logic option has no effect if the street information is in a different address line input field than the PO Box/Rural Route/Highway Contract information.

For example, given the following input address:

AddressLine1: 401 N Main St Apt 1 POB 1
City: Kemp
StateProvince: TX
PostalCode: 75143

Validate Address would return one of the following:

  • If Dual address logic is set to either Normal Match or PO Box Match:

    AddressLine1: PO Box 1
    City: Kemp
    StateProvince: TX
    PostalCode: 75143-0001

  • If Dual address logic is set to Street Match:

    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 select Dual address separation in the Secondary address placement field. 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 select Dual address separation in the Secondary address placement field 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 settingSecondary address placement to Dual address separation. For more information, see Default Options .
