Claim:
A method for validating an address associated with a delivery item, the method comprising: electronically receiving a data file from a sender, the data file comprising one or more addresses that the sender failed to validate with address validation software, wherein a status of the one or more addresses is invalid and the status is indicated in the data file when the data file is received; determining, by a processor, whether the one or more addresses can be validated with a first weekly file comprising extended delivery codes and a second weekly file comprising delivery point verifications; processing, by a processor, the data file using a database of addresses that are represented in neither the first weekly file nor the second weekly file, based on the determining step, including matching the one or more addresses with the addresses in the database; updating the status indicated in the data file, after the processing, to indicate that the status of the one or more addresses previously indicated as invalid is valid; and sending the updated data file to the sender.
