In November 2027, the Fedwire Funds Service will remove the fully unstructured postal address option in favor of a single hybrid postal address format. All parties (intermediaryFi, beneficiaryFi, beneficiary, originator) across all message types must transition from free-text address lines (address1, address2, address3) to a new postalAddress object with mandatory adrLine1, country and city fields.

In advance of the Fedwire enforcement date, all partners must use the new postalAddress structure in production no later than October 2027. Messages sent in the old format after this date will be rejected.
