Structure of an EAN 13 Barcode
The structure of an EAN13 barcode is a specific pattern of 13 digits that encode product information such as the country code, manufacturer code, product code, and check digit. The EAN13 barcode is based on the European Article Numbering (EAN) system, which is a global standard for identifying products in the retail industry.
The structure of an EAN13 barcode can be broken down into four main components: the leading digit, the country code, the manufacturer code, and the product code. Each component has a specific number of digits and serves a unique purpose in identifying the product.
-
Leading Digit:
The EAN13 barcode always begins with a leading digit of either 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. This digit represents the type of barcode used and has no specific product information encoded in it.
-
Country Code:
The next two digits represent the country code, which identifies the country of origin of the product. Each country has a unique two-digit code assigned to it, which is issued by the International Article Numbering Association (GS1).
-
Manufacturer Code:
The following five digits represent the manufacturer code, which identifies the company that produces the product. Each manufacturer is assigned a unique code by GS1, which they can use to create their own product codes.
-
Product Code:
The remaining five digits represent the product code, which identifies the specific product being sold. This code is assigned by the manufacturer and can be used to track inventory and sales data.
In addition to the four main components, the EAN13 barcode also includes a check digit, which is used to verify that the barcode has been scanned correctly. The check digit is calculated based on a specific algorithm that uses the other 12 digits of the barcode. If the check digit does not match the calculated value, the scanner will flag the barcode as invalid.
| Example of EAN 13 Barcode Structure | |
| Leading Digit | 5 (This indicates that the barcode is a standard retail barcode.) |
| Country Code | 90 (This indicates that the product was manufactured in India.) |
| Manufacturer Code: | 12345 (This identifies the company that produced the product.) |
| Product Code | 123457 (This identifies the specific product being sold.) |
| Check Digit | 7 (This verifies that the barcode has been scanned correctly.) |
By understanding the structure of an EAN13 barcode, retailers and manufacturers can ensure that their products are accurately identified and tracked throughout the supply chain. This can help to improve inventory management, reduce errors, and enhance customer satisfaction.
Minimum and Maximum Length of an EAN13 Barcode
The minimum and maximum length of an EAN13 barcode is fixed and cannot be changed. The EAN13 barcode is a fixed-length barcode, meaning that it always contains a set number of digits. The EAN13 barcode has a total of 13 digits, which are divided into four parts: the leading digit, the country code, the manufacturer code, and the product code.
The leading digit is always a single digit between 0 and 9 and indicates the type of barcode used. The next two digits represent the country code, which identifies the country of origin of the product. The following five digits represent the manufacturer code, which identifies the company that produces the product. The remaining five digits represent the product code, which identifies the specific product being sold.
The fixed length of the EAN13 barcode ensures that each barcode contains a unique combination of digits that can be used to identify the product. The length of the barcode also ensures that it can be easily read and decoded by barcode scanners, which are designed to recognize the specific pattern of digits that make up the barcode.
It is important to note that the length of the EAN13 barcode is fixed and cannot be changed. If a product code requires more than five digits, a different type of barcode may need to be used, such as the EAN8 or UPC-A barcode. The EAN8 barcode is similar to the EAN13 barcode but contains only eight digits, while the UPC-A barcode contains 12 digits and is commonly used in North America.
In summary, the minimum and maximum length of an EAN13 barcode is fixed at 13 digits. This ensures that each barcode contains a unique combination of digits that can be used to identify the product and ensures that it can be easily read and decoded by barcode scanners. If a product code requires more than five digits, a different type of barcode may need to be used.
Character Encoding in an EAN 13 Barcode
An EAN-13 barcode is a type of linear barcode that can encode only numeric digits. Each EAN-13 barcode consists of 13 digits, and these digits represent the manufacturer and product information. The encoding scheme of the EAN-13 barcode is based on a combination of two-digit and three-digit numbers, and these numbers are represented by patterns of bars and spaces of different widths. The encoding scheme allows the barcode scanner to identify and decode the information contained in the barcode.
The EAN-13 barcode can encode only numeric digits, which means that it can represent the numbers from 0 to 9. Other types of characters, such as letters, symbols, and punctuation marks, cannot be encoded in an EAN-13 barcode. This restriction on the characters that can be encoded in an EAN-13 barcode is due to the design of the barcode and the encoding scheme used to represent the data.
The EAN-13 barcode is used primarily for retail applications, where it is used to encode the product and manufacturer information of a wide range of consumer goods. The barcode is used to automate the checkout process and to track inventory and sales data. The use of a standard encoding scheme and fixed-length format ensures that the barcode can be easily read and decoded by a wide range of barcode scanners and point-of-sale systems.
In addition to the EAN-13 barcode, there are other types of barcodes that can encode a wider range of characters. For example, the QR code is a two-dimensional barcode that can encode alphanumeric characters, symbols, and even binary data. The QR code is often used in advertising and marketing applications, where it can be scanned by a mobile device to access a website or other digital content.

In summary, the EAN-13 barcode can encode only numeric digits and cannot represent letters, symbols, or punctuation marks. This restriction on the characters that can be encoded is due to the design of the barcode and the encoding scheme used to represent the data. Other types of barcodes, such as the QR code, can encode a wider range of characters and are used in applications where more versatile encoding is required.

Limitations of using EAN13 barcode
Like any technology, EAN13 barcode has some limitations. Here are some of the limitations of using EAN13 barcode:
| Limited Data Capacity: | EAN13 barcode has limited data capacity and can only store up to 13 characters. This can be a limitation in applications where larger amounts of data need to be stored. |
| Limited Versatility: | EAN13 barcode is primarily used for retail products, and may not be suitable for other applications. It is not a versatile barcode format. |
| Sensitivity to Damage: | EAN13 barcode is sensitive to damage, and if the barcode becomes scratched or damaged, it may not be readable. This can be a limitation in applications where the barcode may be subjected to harsh conditions. |
| Limited Scan Range: | EAN13 barcode requires a close scanning range, and the scanner must be able to read the barcode at a specific angle. If the barcode is not positioned correctly, it may not be readable. |
| Requires Line-of-Sight: | EAN13 barcode requires a direct line-of-sight between the scanner and the barcode, and the scanner must be able to see the entire barcode. This can be a limitation in applications where the barcode is not easily visible or accessible. |
| Limited Security: | EAN13 barcode does not offer any security features, and the information contained in the barcode can be easily copied or altered. |
| Cost: | EAN13 barcode scanning equipment can be expensive to purchase, especially for small businesses or organizations. Additionally, implementing a barcode system may require changes to existing processes and systems, which can also be costly. |
| Dependence on Technology: | EAN13 barcode is dependent on technology, and if the scanner or other equipment fails, the barcode may not be readable. This can be a limitation in applications where the barcode is critical for tracking or identification purposes. |
In summary, while EAN13 barcode is a widely used and well-established technology, it does have some limitations that may be important to consider when implementing a barcode system.
