Record Last Updated

A date on each ABN record showing when the source registry last modified it. This is separate from ABN Signal's own weekly detection date.

Why it matters

A recent record-last-updated date tells you the source registry modified this record not long ago. That could mean a field changed, a review happened, or an administrative update was applied.

An older date typically means the record is stable — the business details have not changed recently. The date reflects source-level activity.

Pair this date with ABN status and GST status to build a fuller picture of the record's current state. For example, an ABN marked Active with a record-last-updated date from two years ago likely reflects a stable registration with no recent changes at the source.

How this field relates to change detection

ABN Signal compares weekly data snapshots. When the record-last-updated date shifts between snapshots, it often signals that other fields changed too. The site flags these shifts so you can review them.

The record-last-updated date comes from the source registry. The site's detection date is separate - it marks when ABN Signal noticed the difference during its weekly comparison.

What this means

This date shows when the source registry last modified the record. A record-last-updated date of 15 March 2026 means the registry touched the record on or around that date.

This is not the same as ABN Signal's detection date. The detection date marks when this site spotted the change during its weekly comparison cycle.

What this date tells you

Record-last-updated shows when the source registry last touched the record. A recent date signals fresh data; an older date typically means a stable record with no recent changes. Pair it with ABN status and the site's detection date for a complete timing picture.
