Barcode Technology - EAN-8 Barcode               Hide the description

EAN-8 is an EAN/UPC symbology barcode and is derived from the longer International Article Number (EAN-13) code.

It was introduced for use on small packages where an EAN-13 barcode would be too large; for example on cigarettes, pencils, and chewing gum packets. It is encoded identically to the 12 digits of the UPC-A barcode, except that it has 4 (rather than 6) digits in each of the left and right halves.

Valid characters:  0123456789

EAN-8 is one of the many barcode formats currently in use.

A Barcode is a method of representing data in a visual, machine-readable form.

The barcode formats has two categories:

One-dimensional (1D) --- Barcodes represented data by varying the widths and spacings of parallel lines.

Two-dimensional (2D) --- Using rectangles, dots, hexagons and other geometric patterns to represented data.

EAN - European Article Number, but is now referred to as The International Article Number. It is a standard

describing abarcode symbology and numbering system used in global trade to identify a specific retail product type, in a specific packaging configuration, from a specific manufacturer. EAN barcodes are used worldwide for lookup at retail point of sale.

EAN barcodes only represent the digits 0?, it cannot represent other characters.

The most commonly used EAN standard is the thirteen-digit EAN-13, the less commonly used 8-digit EAN-8 barcode

was introduced for use on small packages, where EAN-13 would be too large. 2-digit EAN-2 and 5-digit EAN-5 are supplemental barcodes, placed on the right-hand side of EAN-13 or UPC. These are generally used for periodicals like magazines or books, to indicate the current year's issue number; and weighed products like food, to indicate the manufacturer's suggested retail price.

EAN-8 codes must be stored in each database as a separate product since there is no way to translate an EAN-8 code

to an EAN-13 equivalent.

EAN-8 has absolutely no compatibility with UPC-E.

An EAN-8 bar code is a 2- or 3-digit number system code followed by a 4- or 5-digit product code. The EAN-8 product

codes are assigned directly by the numbering authority. This has the advantage that any company can request an EAN-8 code regardless of its EAN-13 manufacturer or product code. It has the disadvantage that the EAN-8 codes must be stored in each database as a separate product since there is no way to translate an EAN-8 code to an EAN-13 equivalent.

Calculation of the EAN-8 checksum digit.

It is ease to calculating the EAN-8 checksum digit is simple:
The digit are used from right to left.

For Example: 7654321
Calculate the sum of the numbers of odd and even positions
Odd: 1 + 3 + 5 + 7 = 16
Even: 2 + 4 + 6 = 12

EAN 8 checksum formula:
( 10 - [ (3 * Odd + Even) modulo 10 ] ) modulo 10

So the result of 7654321 is 0:

(10 - [ (3 * 16 + 12) module 10 ] ) modulo 10
(10 - [ (48 + 12) module 10 ] ) modulo 10
(10 - [ (60) module 10 ] ) modulo 10
(10 - [ 0 ] ) modulo 10
(10 - 0) modulo 10
10 modulo 10
0.

Most commonly used barcode types

EAN-13 code: Product barcode, universal, supports 0-9 digits, 13 digits in length, has grooved.

UPC-A code: Product barcode, mainly used in the United States and Canada, supports 0-9 numbers, 12 digits in length, has grooves.

Code-128 code: Universal barcode, supports numbers, letters and symbols, variable length, no grooves.

QR-Code: Two-dimensional barcode, supports multiple character sets and encoding formats, variable length, and has positioning marks.

Why are there many types of barcodes?

There are many types of barcodes because they have different uses and characteristics.

For example, a UPC [Universal Product Code] is a barcode used to label retail products and can be found on nearly every item sold and in grocery stores in the United States.

CODE 39 is a barcode that can encode numbers, letters and some special characters. It is commonly used in manufacturing, military and medical fields.

ITF [Interleaved Two-Five Code] is a barcode that can only encode an even number of digits. It is commonly used in the logistics and transportation fields.

NW-7 [also known as CODABAR] is a barcode that can encode numbers and four start/end characters. It is commonly used in libraries, express delivery and banks.

Code-128 is a barcode that can encode all 128 ASCII characters. It is commonly used in areas such as package tracking, e-commerce and warehouse management.

What is the historical origin of barcodes?

In 1966, the National Association of Food Chains (NAFC) adopted bar codes as product identification standards.

In 1970, IBM developed the Universal Product Code (UPC), which is still widely used today.

In 1974, the first product with a UPC barcode: a pack of Wrigley's gum was scanned in an Ohio supermarket.

In 1981, the International Organization for Standardization (ISO) approved Code39 as the first alphanumeric barcode standard.

In 1994, Japan's Denso Wave Company invented QR-Code, a two-dimensional barcode that can store more information.

About QR-Code

QR-Code was invented in 1994 by a team led by Masahiro Harada of the Japanese company Denso Wave, based on the barcode originally used to mark automobile parts. It is a two-dimensional matrix barcode that can achieve multiple uses.

QR-Code has the following advantages compared with one-dimensional barcodes:

QR-Code can store more information because it uses a two-dimensional square matrix instead of one-dimensional lines. One-dimensional barcodes can usually only store dozens of characters, while QR-Code can Stores thousands of characters.

QR-Code can represent more data types, such as numbers, letters, binary, Chinese characters, etc. One-dimensional barcodes can usually only represent numbers or letters.

QR-Code can be scanned and recognized faster because it has four positioning marks and can be scanned from any angle. One-dimensional barcodes usually need to be scanned from a specific direction.

QR-Code is more resistant to damage and interference because it has error correction capabilities that can recover partially lost or obscured data. One-dimensional barcodes generally do not have such capabilities.

The difference between two-dimensional barcodes and one-dimensional barcodes mainly lies in the encoding method and information capacity. Two-dimensional barcodes use a two-dimensional square matrix, which can store more information and represent more data types. One-dimensional barcodes use one-dimensional lines, can only store a small amount of information, and can only represent numbers or letters. There are other differences between two-dimensional barcodes and one-dimensional barcodes, such as scanning speed, error correction capabilities, compatibility, etc.

QR-Code is not the only two-dimensional barcode. According to the principle, two-dimensional barcodes can be divided into two categories: matrix and stacked. Common two-dimensional barcode types are: Data Matrix, MaxiCode, Aztec, QR -Code, PDF417, Vericode, Ultracode, Code 49, Code 16K, etc., they have different applications in different fields.

The two-dimensional barcode developed on the basis of the one-dimensional barcode has advantages that the one-dimensional barcode cannot compare with. As a portable data file, although it is still in its infancy, it is in the ever-improving market. Driven by the economy and rapidly developing information technology, coupled with the unique characteristics of 2D barcodes, the demand for the new technology of 2D barcodes in various countries is increasing day by day.

About Code-128 barcode

Code-128 barcode was developed by COMPUTER IDENTICS in 1981. It is a variable-length, continuous alphanumeric barcode.

Code-128 barcode consists of a blank area, a start mark, a data area, a check character and a terminator. It has three subsets, namely A, B and C, which can represent different character sets. It can also be used to achieve multi-level encoding through the selection of starting characters, code set characters, and conversion characters.

It can encode all 128 ASCII characters, including numbers, letters, symbols and control characters, so it can represent all characters on the computer keyboard.

It can achieve high-density and efficient data representation through multi-level encoding, and can be used for automatic identification in any management system.

It is compatible with the EAN/UCC system and is used to represent the information of the storage and transportation unit or logistics unit of the commodity. In this case, it is called GS1-128.

Code-128 barcode standard was developed by Computer Identics Corporation [USA] in 1981. It can represent all 128 ASCII code characters and is suitable for convenient application on computers. The purpose of formulating this standard is to Improve barcode encoding efficiency and reliability.

Code128 is a high-density barcode. It uses three versions of character sets [A, B, C] and the selection of starting characters, code set characters, and conversion characters, according to different data Type and length, choose the most appropriate encoding method. This can reduce the length of the barcode and improve encoding efficiency. In addition, Code128 also uses check characters and terminators, which can increase the reliability of the barcode and prevent misreading or missed reading.

Code-128 barcode is widely used in internal management of enterprises, production processes, and logistics control systems. It has many application scenarios, mainly in industries such as transportation, logistics, clothing, food, pharmaceuticals, and medical equipment.

What is the difference between EAN-13 barcode and UPC-A barcode?

The EAN-13 barcode has one more country/region code than the UPC-A barcode. In fact, the UPC-A barcode can be regarded as a special case of the EAN-13 barcode, which is the EAN-13 barcode with the first digit set to 0.

The EAN-13 barcode is developed by the International Article Numbering Center and is universally accepted. The code length is 13 digits, and the first two digits represent the country or region code.

UPC-A barcode is produced by the United States Uniform Code Committee and is mainly used in the United States and Canada. The code length is 12 digits, and the first digit indicates the numeric system code.

EAN-13 barcode and UPC-A barcode have the same structure and verification method, and similar appearance.

EAN-13 barcode is a superset of UPC-A barcode and can be compatible with UPC-A barcode.

If I have a UPC code, do I still need to apply for an EAN?

No need. Both UPC and EAN can identify goods. Although the former originated in the United States, it is part of the global GS1 system, so if you register UPC under the GS1 organization, it can be used globally. If you need to print a 13-digit EAN barcode, you can add the number 0 in front of the UPC code.

UPC-A barcodes can be converted to EAN-13 barcodes by prepending 0. For example, the UPC-A barcode [012345678905] corresponds to the EAN-13 barcode [0012345678905]. Doing this ensures Compatibility with UPC-A barcodes.
