Free Code 128 barcode generator
Create Code 128 barcodes for SKUs, inventory bins, shipping labels, asset tags and tickets. Code 128 encodes letters, numbers and symbols compactly, which makes it the most flexible barcode for internal use.
Why Code 128?
Code 128 can encode the full set of keyboard characters, upper and lower case, and packs data more tightly than older formats like Code 39. That makes it ideal for SKUs such as "BOX-0042-A", serial numbers, order numbers and warehouse locations.
Common uses
Warehouses use Code 128 for bin and pallet labels, shops for internal SKUs, IT teams for asset tags, event organisers for tickets, and logistics companies for shipping labels. Any handheld or phone barcode scanner can read it.
