How to Use the Code 128 Barcode Generator
Code 128 is incredibly versatile because it supports all letters (uppercase and lowercase), numbers, and standard ASCII symbols. This makes it perfect for generating barcodes from complex SKU numbers or product IDs.
- Enter Your SKU or ID: Paste your alphanumeric data into the text box. The generator automatically uses the most efficient internal encoding (A, B, or C) to keep the barcode as compact as possible.
- Adjust Size: Because Code 128 can hold a lot of data, long text strings can result in very wide barcodes. Use the Width setting to scale it down if it needs to fit on a small asset tag.
- Download & Print: Click download to get a crisp PNG image that will scan perfectly with any standard laser or 2D imager scanner.
