LEADTOOLS provides fast, highly accurate, and reliable USPS and 4-State Barcode detection, reading, and writing support
for .NET (C# & VB, Core, Xamarin, UWP), C/C++, iOS, macOS, Linux, Java, and web developers.
The award-winning LEADTOOLS libraries help programmers add full-featured USPS and 4-State Barcode technology to their applications in record time.
LEADTOOLS supports several 2-state and 4-state barcode symbologies employed throughout the world by various post mail office systems.
These barcodes are comprised of bars of different heights, as opposed to different widths that most linear 1D barcodes employ.
2-state barcodes are able to encode the digits 0-9 and are effectively used for zip codes, routing numbers, and tracking numbers,
while 4-state barcodes can encode alphanumeric characters to encode the entire address.
POSTNET was developed by the United States Postal Service (USPS) to represent the 5 or 9 digit ZIP code or an 11 digit "Delivery Point Code" of US destination addresses.
A POSTNET symbol can be printed upon an envelope and be used to facilitate faster mail sorting.
These symbols are printed upon flat pieces of mail such as magazines and envelopes.
Post Alpha Numeric Encoding Technique (PLANET)
PLANET is similar to POSTNET in that it uses half and full height bars to encode data, always begins and ends with a full bar, and digits are represented using a two of five code.
The major difference between POSTNET and PLANET is that in POSTNET full bars represent "on" bits while in PLANET full bars represent "off" bits.
PLANET is used by the United States Postal Service to identify and track mail during delivery.
USPS 4-State Customer Barcode (USPS4CB)/Intelligent Mail Barcode
Intelligent Mail Barcode, more commonly known as 4-State Customer Barcode or USPS4CB, is a 65-bar code used by the United States Postal Service for domestic delivery.
It is designed to provide improved functionality and information than its predecessors POSTNET and PLANET.
It effectively combines the routing ZIP code and tracking information into a single barcode.
Royal Mail (RM4SCC)/CBC (Customer Bar Code)
The RM4SCC symbol is used by the Royal Mail Cleanmail service.
The Royal Mail Service has specific requirements placed upon this symbol to ensure maximum readability and efficiency during the mail routing process.
Australia Post 4-State
Australia Post 4-State is used by Australia Post for postal code and automatic mail sorting.
Australia Post has chosen the 4-State barcode, a derivation that is already used successfully by other postal administrations.
It comprises four types of bars (the four states), each of which has a distinct name, value, and barcode symbol.

For many of us, a day hardly goes by without seeing a barcode. For software developers, this creates immense opportunities to create software that handles both the encoding and decoding of barcodes. How does a developer or project manager get started on their path to success? When you boil it down, there are two primary questions you should ask: Which barcodes should I use? How will I use them? This white paper will help clear the muddied waters surrounding both of these questions by detailing several of the most popular barcodes and how programmers can use the award winning imaging SDK technology in LEADTOOLS to quickly and easily develop their application.
