NCOA Inactive address

Left house
Using Australia Post’s NCOA database, we can confirm people who have moved address.

They have moved from their original residential address but have not given Australia Post consent to reveal their new address and Datawash has no knowledge of their new address details.

Similar to the NCOA process, our database is refreshed on a weekly basis and we match both the full name and address and flag the records to indicate that they no longer live at that address.

We also add the date the move has been recorded.
