1. What is the Barcode on product packaging?

All goods and products need to have barcode  printed on their packagings. Barcodes are their “identity cards”, to help buyers distinguish quickly and accurately different types of goods.

A barcode is one of the identification technologies that automatically collects data from products, services, organizations, or locations – based on assigning a code (or number) to each object. Those codes will be in the form of alternating parallel gaps, arranged in a certain coding rule so that the scanner device can read them.

5. What to notice when scanning barcode on packaging?

There are many reasons why the barcode on packaging cannot be scanned, they may be corrupted or simply printed on materials that are not up to standard quality.

– Code readers are not compatible with barcodes

There are many types of barcodes on the packaging, each will have a corresponding barcode, because the encoding is different, so the size and shape cannot be the same.

– Barcode printing error

Most bar codes on products are printed by the manufacturer. Each manufacturer prints the code on a different packaging material even the color of the barcode is different. Others print where there is no flat surface, which makes reading them more difficult.

– Barcode color errors

The color of the barcode also greatly affects whether the code can be read or not, the scanner can only read the bar code when dark bars are used on a light background, in contrast to the printed barcode.

– Barcode position is not correct

Check if your bar code is at the corner or the edge of the product packaging, whether it is hidden or not.

– Barcode printed product surface

If the product has a transparent or translucent color, this will cause problems with color contrast.

– Barcodes are blurred or broken

Check if all barcode lines are clear and clear. redundant ink points, broken, if a barcode scanner will be difficult to read in this case.

– Barcode length does not match

A fairly common mistake during print design. If you notice you may recognize barcodes that can vary in length. The barcode length here is the width of the barcode, it may be too long or too short.

In addition, the process of transporting the product may cause the barcode label to peel, scratch, or fade. Ensure the barcode is always stable when shipping. In particular, some barcode labels are very sensitive to the environment, so pay attention to the use of paper label materials or product packaging when printing bar codes.

6. What is the real meaning of barcode on product packaging?

The barcode we usually see on the package consists of two parts:

  • Codes of goods for people to identify
  • Barcodes for computers and scanners are included in the system management

– Barcodes on packaging have 2 common standards: UPC-A and EAN

  • The UPC-A standard is a 100% American product: this standard is specific to the Canadian and US markets
  • EAN: used for markets in Europe, Asia and many other countries

You can refer to bar code printing and usage regulations at the GS1 Vietnam website.

In Vietnam, most goods on the market apply EAN standard with 13 numbers, divided into 4 groups:

Group 1: From left to right, the first three digits are the country code (territory)

Group 2: Next with four digits is the enterprise code

Group 3: Next with 5 digits is the goods code

Group 4: The last digit (right) is the check digits
