Frequently Asked Questions
How are the nearest postcodes calculated?
Distances are straight-line ("as the crow flies") measurements between postcode centroids, in kilometres. Actual driving distance will be longer due to road layouts.
How many nearest postcodes can I find?
You can retrieve up to 50 nearest postcodes in a single search. For every postcode within a set radius instead of a fixed count, use our Postcode Radius Search tool.
Is my data stored?
No. All processing happens in your browser. We don't track your searches or store any data. When you share a link, the postcode is simply included in the URL.
Why wasn't my postcode found?
We use a database of 2,640 Australian postcodes built from official address data, covering standard delivery-area postcodes. PO-box-only and specialist codes aren't included.
