The 4 essential barcodes every business should know

If you run a business, you need to understand the different barcodes you'll work with every day so you can get the most out of them.

The 4 essential barcodes every business should know

At StockAgile we work with several types of barcodes: EAN-13, EAN-8, UPC-A and CODE-128.

With EAN and UPC codes you can only use numbers, no characters and no letters.

There are two types of EAN:

EAN (European Article Number) was first adopted by European countries, but today it’s used by almost every country except the United States and Canada, which use UPC.

  • EAN-13

As the name suggests, the code is made up of 13 digits: 1 digit on the left, 6 in the middle and 6 on the right. Two different products can never share the same code.

The barcode is divided into 4 parts.

The first digits identify the country that issued the product. The code is structured into the country-of-origin number, the manufacturer number and the product identifier number.

  • EAN-8

It works the same way as EAN-13, but saves space since it only contains 8 digits. It’s used for retail products such as sweets, cigarettes and other small items.

The eight digits are split into two blocks of 4. Two of them indicate the country, 5 identify the product and one is the check digit.

  • UPC-A

This is the most widely used code in the United States and Canada, typically for supermarkets and retail products.

The code has 12 digits. It starts with a number that classifies the product (for example, whether it’s a pharmacy item, a retail product, etc.). Then comes the manufacturer and product information. The final digit is the check digit.

  • CODE-128

It’s mainly used in logistics and warehousing. It’s a highly versatile code that supports symbols, numbers and letters, and can hold a large amount of data.

The barcode has 6 sections. The first and last sections are quiet zones that reference other elements of the code. Each character is made up of 3 bars and 3 spaces.
