What is a barcode number?

A barcode number is a unique sequence of numbers and/or letters that is represented by a series of parallel lines of varying widths. It is used to identify a specific product or item and can be scanned by a barcode reader to retrieve information such as price, product details, and inventory levels.

A barcode number is a series of numeric and/or alphanumeric characters that uniquely identifies a particular item. Barcodes are typically used to track items as they move through a supply chain, from manufacturing to the end consumer. Barcodes can be read by barcode scanners, which convert the barcode number into a digital format that can be stored in a database or otherwise processed.
