  • What is NCOA?

    The matching of people on a client’s mailing list to the name and address information stored by Australia Post when a mail redirection is lodged. Individuals who give consent to Australia Post to release their new address will be included in the output if matched with the client’s mailing list

    Over 70% of Australians that move every year pass on new address details to Australia Post using the mail redirection service. Approximately 25% give consent to Australia Post for their movement details to be released. The residual that do not give consent for their new address details to be released can be contacted using the ReConnect service from Australia Post.

    The NCOA information is updated on a weekly basis to ensure you obtain the latest information available.

  • Australia Post’s NCOA ReConnect Service (Non Consents)

    Australia Post can contact people that have lodged a mail redirection form but have not given consent for the release of any new address information (NCOA non consent). Letters are sent on behalf of a client by Australia Post requesting that the client be informed of their new address details.

    Approximately half of the recipients of a ReConnect request letter decide to allow the client to have their new address details.
