We recommend that you use the following elements for outbound Accounts Receivable (AR) invoices:

Buyer's Address Line 1 (Invoice/AccountingCustomerParty/Party/PostalAddress/StreetName)
Buyer's City (Invoice/AccountingCustomerParty/Party/PostalAddress/CityName)
Buyer's City Post Code (Invoice/AccountingCustomerParty/Party/PostalAddress/PostalZone)

If you cannot use these, you can use up to 2 Buyer's Additional Address Line (Invoice/AccountingCustomerParty/Party/PostalAddress/AddressLine/Line) elements.

General information about Buyers is provided in the VRBL: Buyers topic.

For inbound Accounts Payable (AP) invoices, the KSF (FA3) format uses 2 generic free-text elements to model address lines. Therefore, you can only model these lines for inbound AP invoices.
