What is a 1D Barcode?

A 1D (one-dimensional) barcode is a visual representation of data in a machine-readable format. It consists of a series of parallel black bars and white spaces of varying widths. When scanned, these patterns are converted back into their original data, which is typically a string of numbers or characters.

Common Barcode Formats

This tool supports a variety of standard barcode formats, each with its own specific use case:

• CODE128: A high-density, versatile barcode capable of encoding all 128 ASCII characters. Widely used in logistics and transportation.
• EAN-13 & UPC-A: The most recognizable barcodes used on retail products worldwide for checkout and inventory management.
• CODE39: An older but still common format that can encode numbers, uppercase letters, and some symbols.
• ITF-14: Used for marking cartons and shipping containers, encoding the product's GTIN.
