USI webservices version 3 will be decommissioned in early October 2021. Webservices version 4 went live on 30 September 2020.  All providers who use the USI Registry System through their SMS will need to move to the latest version.

New providers who onboarded after the latest version was introduced will be using version 4 and do not need to make any changes.

To find out if your SMS is using the most up to date version of webservices, talk to your software developer (digital service provider). For any queries, contact us at IT@usi.gov.au
