Linear Barcode
A linear barcode, also known as a one-dimensional (1D) barcode, is a series of parallel lines of varying widths and spaces that encode data, typically alphanumeric characters.
In simple terms, it’s like a secret code made of black and white lines. It’s a one-dimensional barcode that stores information using a series of vertical bars and spaces of different widths. These barcodes can be scanned by a machine to quickly read data, like product numbers or prices.
You’ve probably seen linear barcodes on grocery items, books, and shipping labels. When scanned at a checkout counter, the barcode tells the system what the product is and how much it costs.
Some common types of linear barcodes include UPC (used in retail), Code 128 (used for shipping and inventory), and EAN (used worldwide for products).
Characteristics of Linear Barcodes
- Encode data horizontally in a single line
- Require a scanner to read the width and spacing of the bars
- Store limited amounts of data (usually up to a few dozen characters)
- Are widely used in retail, logistics, and healthcare
Linear barcodes are fast, reliable, and widely used in industries like retail, healthcare, and logistics to track products and manage inventory efficiently.

Next time you’re looking at a food label, a book, or shopping for a new pair of jeans, notice that linear barcodes are all around us! They are widely used today due to their simplicity, cost-effectiveness, and quick scanning capability.
