5.5 4-State Postal Codes

5.5.1 Australia Post 4-State Symbols

5.5.1.1 Customer Barcodes

Australia Post Standard Customer Barcode, Customer Barcode 2 and Customer Barcode 3 are 37-bar, 52-bar and 67-bar specifications respectively, developed by Australia Post for printing Delivery Point ID (DPID) and customer information on mail items. Valid data characters are 0-9, A-Z, a-z, space and hash (#). A Format Control Code (FCC) is added by Zint and should not be included in the input data. Reed-Solomon error correction data is generated by Zint. Encoding behaviour is determined by the length of the input data according to the formula shown in the following table:

5.5.1.2 Reply Paid Barcode

A Reply Paid version of the Australia Post 4-State Barcode (FCC 45) which requires an 8-digit DPID input.

5.5.1.3 Routing Barcode

A Routing version of the Australia Post 4-State Barcode (FCC 87) which requires an 8-digit DPID input.

5.5.1.4 Redirect Barcode

A Redirection version of the Australia Post 4-State Barcode (FCC 92) which requires an 8-digit DPID input.

5.5.2 Royal Mail 4-State Country Code (RM4SCC)

The RM4SCC standard is used by the Royal Mail in the UK to encode postcode and customer data on mail items. Data input can consist of numbers 0-9 and letters A-Z and usually includes delivery postcode followed by house number. For example "W1J0TR01" for 1 Picadilly Circus in London. Check digit data is generated by Zint.

5.5.3 USPS OneCode

Also known as the Intelligent Mail Barcode and used in the US by the United States Postal Service (USPS), the OneCode system is due to replace the PostNet and PLANET symbologies by 2009. OneCode is a fixed length (65-bar) symbol which combines routing and customer information in a single symbol. Input data consists of a 20 digit tracking code, followed by a dash (-), followed by a delivery point zip-code which can be 0, 5, 9 or 11 digits in length. For example all of the following inputs are valid data entries:

"01234567094987654321"
"01234567094987654321-01234"
"01234567094987654321-012345678"
"01234567094987654321-01234567891"
