Australia Post 4-state
Australia’s postal barcode, built on the same four-state idea.
- Type
- Four-state postal
- Encodes
- A sorting code and delivery point, with optional customer data
- Structure
- A leading format control code sets what the rest of the symbol contains
- Off by default
- Enable it under Settings → Scanning engine
The Australia Post symbology follows the four-state pattern — bars that are full, ascending, descending or short — and adds a format control code at the front. That leading code tells the reader what kind of symbol it is looking at and therefore what the rest of the bars mean, which is how one format covers both plain addressing and longer codes carrying customer information.
The practical effect is that an Australian mailpiece or parcel can carry routing data and sender-specific reference data in the same strip of bars.
As with the other postal formats, it was designed for sorting machinery rather than handheld readers, which is why support outside postal equipment is uncommon.
Where you meet it
Australian mail and parcels.
Can a phone scan an Australia Post barcode?
With TRAKWIND Scan selected and the postal formats enabled under Settings → Scanning engine, yes. A standard phone scanning engine will not read it.
How to scan it with your phone
- 1
Install Barcode & QR Scanner Keyboard from Google Play and enable it as a keyboard.
- 2
Open Settings → Scanning engine and choose TRAKWIND Scan.
- 3
Tap the barcode key on the keyboard and point the camera at the code.
This format ships switched off. Turn it on in the same Scanning engine screen before you scan.
The value is typed into whatever field you were already in — a spreadsheet, an ERP screen, a web form. There is nothing to integrate.
