Mail barcodes are a unique type of barcode used in postal services to identify mail items and enable tracking of their movement. These codes play an important role in the efficient operation of postal services and provide businesses with valuable data about their outgoing mail. In this blog post, we will explore the various types of mail bar codes used in postal services, explain how to read them and look at the advantages they offer businesses. We will also provide best practices on selecting the right mail barcode for your needs and helpful recommendations on proper use and reading. By unlocking the secrets of mail bar codes, you can ensure that you are getting the most out of your postal service experience.


Mail bar codes are a unique type of barcode used in postal services to identify mail items and enable tracking of their movement. They are an essential part of any postal service, as they provide businesses with valuable data about their outgoing mail. In this section, we will explore the purpose and different types of mail bar codes, as well as the anatomy of a mail bar code and how it can be used for tracking purposes. We will also discuss the advantages that mail bar codes offer businesses, along with an explanation of how to read them.

At its most basic level, a mail barcode is a machine-readable code that contains information about what is inside the package or envelope being sent. This information includes who it was sent from, where it’s going, what type of delivery service is required, and more. It is encoded into a sequence of bars or lines which can be scanned by automated sorting machines at post offices or other locations where mail is processed. Each type of mail bar code will contain different information depending on its intended use; for example, some may include an expiration date or signature requirement while others may simply contain sender and recipient addresses along with a tracking number.

The anatomy of a mail bar code consists of several parts: firstly, there are two start characters which indicate when the code begins; then there follows the address area; after that comes the optional auxiliary area (which can contain additional information such as expiration dates); then comes the end character; finally there is the check digit which helps to verify that all information has been correctly entered into the code. The combination of these parts form what’s known as a “linear” barcode – meaning that all information appears in sequence from left to right without interruption – although some codes may also include two-dimensional elements such as QR codes for added security or convenience.

Using mail bar codes offers businesses several advantages over traditional methods of sending letters and packages. For starters, they allow users to quickly track their items via specialized software programs or websites which provide real-time updates on where exactly your package is in transit between the sender and recipient. Additionally, they make sorting large amounts of incoming items far easier due to automated scanning machines which can quickly identify each package based on its unique code – saving time and money for both senders and receivers alike! Finally, using this technology allows for greater accuracy when sending out bulk orders since each item can be easily identified by its individual code if needed later down the line for verification purposes.

Reading a mail bar code isn’t difficult but it does require some practice in order to become proficient at decoding them accurately every time. The key thing to remember when reading one is that all characters within each code appear from left to right without interruption; so start at one end and work your way through until you reach the other side! Additionally, it’s important not to confuse similar-looking characters with one another; once you get familiar with what each character looks like you should be able to spot them easily enough! Lastly, never forget about checking for errors before using any given code; incorrect numbers could lead to costly delays so always double-check before sending out your parcel!

Types of barcodes used in postal services

Different types of barcodes are available to postal services for the purpose of identification and tracking of mail items. Generally, these codes can be broken down into two main categories: linear and 2D. Linear barcodes are the most commonly used for postal services, with Code 39 and Code 128 being the two most popular ones. These use vertical lines to signify numbers or letters that represent data like origin, destination, type of delivery, weight, etc., but are limited in their capacity for storage.

2D barcodes have more complex patterns made up of dots or squares arranged in a matrix format; this allows them to store more information such as tracking numbers, dates etc., which is beneficial when sending out bulk orders or packages with multiple items. An example of this technology is Mobile Barcode which uses a mobile device’s camera to scan a code on a package without any additional hardware.

Businesses should consider both advantages and disadvantages associated with each type when selecting a barcode for their needs; linear codes generally offer faster scanning speeds but may not provide enough detail if dealing with larger shipments or multiple items per package; 2D symbols take up lesser space than traditional linear symbols but have a greater capacity for information storage. While lightweight letters should utilize simpler linear codes, heavier parcels require more detailed tracking information provided by 2D codes. Moreover, it is important that businesses review their coding system regularly against recent developments so as to remain abreast with current standards and maximize efficiency in their operations involving mail bar codes.


Understanding the anatomy of mail bar codes is crucial to utilize them effectively. These codes are made up of a unique combination of lines and spaces, measured in millimeters, which are read from left to right by scanners. Different types of barcodes provide varying levels and types of information – linear codes may be scanned more quickly but lack the capacity for large shipments, while 2D symbols have greater storage potential.

Mail bar codes can also be used to track items through their journey with postal services, which helps streamline processes such as sorting mail to the correct destination quickly and accurately. Additional data may also be included such as delivery confirmation or estimated delivery timeframes. With this in mind, businesses should ensure they use the best type of barcode for their needs and adhere to best practices when selecting one for postal services so they can maximize efficiency every time.

Mail bar codes can be a game-changer for businesses of all sizes, by streamlining the processes involved in sending and receiving mail. Whether it’s tracking items or sorting through large volumes of mail quickly and accurately, understanding the anatomy of a mail bar code is an essential first step to unlocking its full potential.

It is also important to stay up-to-date with current standards and regularly review your coding system, as well as look into case studies that demonstrate how others have successfully implemented them. By doing so, businesses will be able to improve their mailing operations while providing an improved customer experience due to better efficiency and delivery accuracy.

In conclusion, mail barcodes are a powerful tool for businesses that want to take their postal services to the next level. With the right knowledge and implementation strategies in place, they can provide numerous benefits such as increased accuracy when sending out bulk orders and enhanced tracking capabilities throughout the journey with postal services.
