AVS error 4763

ErrorNAT00020

Address-suburb, locality or town

What it means

Triggers when a training delivery organisation location is reported with postcode 'OSPC' (overseas) but its suburb appears on the Australia Post list of Australian suburbs.

How to fix it

Use the correct AU postcode for the suburb, or if a genuine overseas locality with an Australian suburb name, contact NCVER Client Support.

Does RTObase catch this automatically?

This check needs an external source (training.gov.au or Australia Post), so it can’t be caught from your data alone, but RTObase surfaces it from your imported AVS report and deep-links you straight to the fix.
