Bulk Barcode Generator for Ean-8

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.
