What Is Code 128?

The Code 128 barcode is a high-density linear symbology that can encode all 128 ASCII characters as well as text, numbers, and various functions (from ASCII 0 to ASCII 128.) 

It is also known as ISBT-128, GS1-128, UCC-128, EAN 128, and USS Code 128 and is often used for many applications.

There are 106 distinct printed barcode designs in code 128. 

What is barcode code 128?

With three distinct Code 128 start characters available to program the beginning character set, each printed barcode may have one of three different meanings depending on which character set is being used. 

The barcode symbology also has functions for changing character sets and encoding Application Identifiers.

Because of the many character sets, the barcode Code 128 may be difficult to use. 

For this reason, IDAutomation offers the Code 128 auto function, "code 128( )," in a number of its Font Tools, Components, and Applications.

The whole bar code 128 is made up of a start character, data digits, a modulo 103 check digit, and a stop character.

Code 128 Composition

The barcode 128 format includes the data itself, a leading "quiet zone," one of three start codes, a check character, a stop character, and a following quiet zone.

What are the components of barcode 128?

• The quiet zone: The region between the bars and spaces that are clean and unmarked (the silent zone) enables scanners to establish baseline values for the color and reflectance of the material they are scanning. 

The dynamic determination of what constitutes a "space" and what constitutes a "bar" is made using these numbers.

• The start code: The beginning of a Code 128 barcode is indicated by one of three codes, the start code. 

The three "character sets" or "character modes" in the barcode types 128 specification are defined.

The Start-A, Start-B, and Start-C codes distinguish between the character sets that will be utilized. 

To more effectively encode the data, the character set may also be altered in the midst of the barcode.

• The Code 128 data: Strips of bars and spaces are used to encrypt the Code 128 data. 

The encoding is shown in the table below using a binary scheme, with a "1" standing for a single-width bar and a "0" for a space. 

Keep in mind that groups of 0s or 1s just show as wider bars or spaces.

Components of code 128

• The checksum: The checksum, which is part of the barcode, is a digit that confirms the accuracy of the data that was just read in. 

The weighted sum of the values of each digit in the message that is being encoded, including the start character, serves as the basis for the modulo 103 computation used to determine the checksum digit. 

The bar-and-space pattern known as the stop code denotes the conclusion of a barcode.

Code 128 Character Composition

Although the Code 128 character set comprises only 102 characters, this symbology supports all 128 lower-ASCII characters. 

This is possible as Code 128 uses three various sets of 102 characters (Code Set A, Code Set B, and Code Set C). 

The starting character determines the default code set for one of types of barcode such as Code 128. 

Yet, it is possible to switch between different character sets and use a combination of them in a single symbol. 

Code 128 gives the highest possible character density since you encode data. The three character sets may be summarized as follows.

• Code Set A: Include all numeric characters (0-9), uppercase letters (A-Z), punctuation marks, seven special characters, and "control characters" (ASCII values ​​00-95).

Code 128 character set

• Code Set B: Include all numbers (0-9), uppercase and lowercase letters (A-Z, a-z), punctuation, and 7 special characters (ASCII values ​​32-127).

• Code Set C: Contain all pairs of digits from 00 to 99 and 3 special characters. Although this code set is numeric only, each character represents two digits.

Code 128 Applications

Like its subset GS1-128, Code 128 is widely utilized all over the world. 

Due to its capacity to store a wide variety of data, it plays a crucial part in supply chains and inventories in several sectors. 

What are the applications of code128 barcode?

The product's production date, open date, weight, and other information are examples of this data. Some of the applications of the code may be seen mentioned below:

• Used often in the transportation sector to identify products and containers.

• Used to identify and label a range of wholesale goods in the packaging and wholesale sector. 

For instance, FedEx and other businesses automate delivery and tracking by using Code 128 barcodes on packaging slips.

• Widely used in the pharmaceutical, medical equipment, and healthcare sectors. It is employed, for instance, in the labeling of blood transfusion items to include the Donor Identification Number.

• Used in sectors such as the manufacturing of clothing, food, and medical equipment.

• Used for distribution and order in the logistics and transportation sectors.

• Used together with code 39 in any cutting-edge brick-and-mortar business.

How To Calculate Code 128 Check Digit?

Does code 128 have a check digit? Code 128 is self-checking and does not normally require a check digit. 

However, a module 103 checksum digit can be added for applications requiring very high accuracy. 

Follow our instructions on code 128 check digit calculation below:

• Number each character position 

• Each character's value is multiplied by its position number

• Sum the products of the check digit calculator for code 128 in step 3 and add to the start code value. 

• Next, divide the sum of the products by 103. 

• The remainder value in step 4 is the symbol check character value. Then you need to find the corresponding checksum digit according to the ASCII value.

What Is GS1 128 Barcode?

Besides the data given by the JAN code and the existing standard distribution code (ITF), GS1 128 barcodes can offer a variety of data, such as distribution and business transaction data.

The information below can be encoded with a GS1-128 barcode:

• Quantity in package

• Package number

• Lot number

• Capacity, weight, and cubic capacity

• Location number

• Account code of customer

• Order number of customer

For each application, a barcode label is created using the necessary data.
