The EAN-8 barcode is a omnidirectional, numeric 1D barcode with 8 digits, and is the condensed version of the EAN (European Article Number) barcode. EAN / UPC barcodes employ a 1-digit checksum as an error detection mechanism.
Example Barcode
The following example barcode encodes the information 0123456 as an EAN-8 barcode:
Details
The EAN-8 barcode encodes 8 digits (7 digits plus one check digit) of information, and has a symbol length of 81 modules. 1
Barcode Breakdown
The barcode is split into the following sections:
-
GS1 Prefix - Two to three digits indicating the manufacturing company's GS1 prefix, which is usually associated with a specific country. This does not mean that the product was manufactured in that specific country. 2
-
Product Code - Variable length product code assigned by the governing authority of the GS1 prefix's corresponding country.
-
Checksum Digit - Final digit, which is used to ensure data integrity.
Managing Organization
The EAN standard was managed by the EAN Association until 2005, when the UCC and EAN (European Article Number) merged to form GS1 (Global Standards One), at which point the EAN became GS1. 3
Platform-Specific Notes
Barcode Xpress will generate an error if you have characters in your barcode value that are not allowed. You can have 7 or 8 digits in the EAN-8 barcode value. You don’t have to include the 8th digit (checksum) since Barcode Xpress automatically adds it.
EAN-8 requires a quiet zone, which should be at least the width of 10 narrow bars. This means that if you set the MinimumBarWidth property to 3 pixels (narrow bar size), you should set the HorizontalWhiteSpace property to 30 pixels.
The EAN-8 barcode is also commonly written with 2 different bar heights. Typically, the height of the left and right guard bars are greater than the height of the bars encoding the actual barcode value, essentially creating a notch in the barcode where the text value can be written. Barcode Xpress provides the user with control over the size of this notch with the TextNotchPercent property.
The TextNotchPercent property can be set to a value of 0 to 50. This number represents the percentage of the tall bar height the short bars will be shortened by. For example, if TextNotchPercent is 10, and the bar height is set to 100 pixels, the tall bars (left and right guard bars) will be 100 pixels tall, and the short bars (bars encoding the value) will be 90 pixels tall.
