Regional Postcode Checker (Australia)
Check a postcode and its actual state or territory against current designated regional-area rules. Postal validity and visa eligibility are not verified.
Regional postcode checker
Match a postcode and its actual state or territory against the current regional-area rules.
Rules checked 2026-11-04. This is a classification lookup, not a postal-address validation service.
Postal validity: not verified. Check that the postcode is assigned to the actual address and selected state or territory. No suburb, locality or street address has been verified.
A regional category alone does not establish visa eligibility, points, nomination, processing priority or a graduate visa extension. The applicable visa rules, dates and other requirements still need to be checked.
Optional external postcode search, not an address or migration classification check. No map is loaded here.
Sources: LIN 22/022, section 3 · Home Affairs postcode table.
These are the current rules, not a historical visa-date assessment. Earlier events or grants may use earlier rules. Recheck the official sources when making a decision.
What this lookup establishes
The checker matches the postcode against the state or territory you select. It uses section 3 of LIN 22/022, cross-checked against the Home Affairs table on 4 November 2026.
A Category 2 or Category 3 match is conditional on the postcode belonging to the actual address in that state or territory. The checker does not validate postal allocation, street addresses, locality names, residence, study or employment. A number outside the listed ranges is not automatically an invalid postcode.
Why the state or territory matters
Use the physical address’s state or territory, rather than inferring it from the postcode. Border areas and territories can use postcodes that do not follow a simple first-digit rule. The Australian Capital Territory, Northern Territory, Norfolk Island and other territories have their own entries in the instrument.
Postcodes are displayed with four digits, including leading zeroes. For example, an entry of 800 is normalised to 0800. This formatting step does not verify that a postcode exists.
Classification is not visa eligibility
Category 2 identifies designated cities and major regional centres; Category 3 identifies regional centres and other regional areas. A category alone does not award migration points, establish eligibility for a visa or nomination, guarantee faster processing, or determine graduate visa duration. Check the requirements and relevant dates for the specific visa and circumstances.
This tool applies the current tables. It does not decide which historical instrument applies to an earlier application, nomination or visa grant. Home Affairs flags some Queensland entries as not applicable to visas granted before 5 March 2022.
Optional location search
After a lookup, you can choose Open in Google Maps. This opens an ordinary external search for the postcode and selected state or territory. No map is embedded, no Maps API is loaded, and no street location or regional boundary is verified by that link.
