Barcode Numbering Explained – Barcode Number Meanings and How They Work

barcodes

The barcode’s first appearance was in an Ohio supermarket in the mid-70s. Those little black and white stripes went on to change the world.

It’s almost inconceivable to think of a world without them. Every trip to a retailer involves scanning one.

Their applications extend beyond retail. They’re used to reduce the number of errors in the medical field and are even used in mobile gaming.

Curious about how they work and what all the numbers and lines mean? Let’s learn about the interesting world of barcode numbering.

Barcode Basics

The first barcode was actually just a few lines in the sand. Norman Joseph Woodland was thinking of Morse code when he absentmindedly trailed his fingers on the beach.

He wanted a way to encode information easily. From Morse code, they adapted the parallel bars to hold different kinds of information.

Two Types of Barcodes

Barcodes come in one of two types: one dimensional and two dimensional. They’re usually referred to as 1D and 2D respectively.

1D are what most people think of when they think of barcodes. They’re a series of black and white lines that contain basic information about the goods that they’re printed on.

2D holds more information. They can tell your computer about the price, quantity, and more about the products.

Adding a UPC

Adding a UPC, or Universal Product Code, to an item adds even more information to a standard barcode. Standard UPCs have five numbers that identify the manufacturer, the product itself, and then one number at the start with specific information.

At the beginning of a UPC code, that one number can tell you a lot about the item. For example:

  • numbers 0, 1, 6, 7 and 8 are for everyday, regular items
  • number 2 is used for items measured by weight
  • 3 is used for medical items
  • 4 is used for non-food items
  • coupons use numbers 5 and 9

Scanning the series of bars, spaces, and numbers translates it into text that your computer can read. Keep reading to learn more about how businesses have benefited from this simple black and white label and — how you can make your own.
