What is GS1 Barcode

Barcodes, including EAN and UPC, are symbols that can be scanned electronically using laser or camera-based systems.

Body

They are used to encode information such as product numbers, serial numbers and batch numbers. Barcodes play a key role in supply chains, enabling users including retailers, manufacturers, transport providers and hospitals to automatically identify and track products as they move through the supply chain. GS1 manages several types of barcodes, many of which comply with ISO standards. Each is designed for use in a different situation.

GS1 HK barcode 489

GS1 HK is the only authorised body in Hong Kong to assign barcode with “489” prefix (GTIN).  We have never authorised any organization to issue barcode on our behalf.

A barcode (technically called “GTIN” or “Global Trade Item Number”) is a number represented in vertical lines of varying widths printed on labels to uniquely identify items enabling the rapid and un-ambiguous identification of products, assets, documents to people using a scanner.

1. GS1 EAN/UPC barcodes

Instantly-recognisable 1D barcodes used in retail all over the world and are printed on virtually every consumer product. They can be scanned at POS and are the longest-established and most widely-used of all GS1 barcodes.

The GS1-128 barcode can carry any of the GS1 identification keys, plus information like serial numbers, expiration dates and more.

3. GS1 DataBar barcodes

DataBar barcodes are often used to label fresh foods. These barcodes can hold information such as an item's batch number or expiry date, in addition to other attributes used at the point-of-sale such as the item weight.

DataBar barcodes are often used in retail, and can be read by some point-of-sale laser scanners. See how it works >>

The GS1 DataBar family consists of seven symbols in total: four for use at point-of-sale and three not for use at point-of-sale.

The symbols for use at point-of-sale are shown below:

4. Two-dimensional (2D) barcodes

Two-dimensional (2D) barcodes look like squares or rectangles that contain many small, individual dots. A single 2D barcode can hold a significant amount of information and may remain legible even when printed in a small size or etched on to a product. 2D barcodes are used in a wide range of industries, from manufacturing and warehousing to marketing logistics and healthcare.
