What is Code 128 used for?
Code 128 is the workhorse of internal logistics. Unlike retail symbologies it is variable-length and encodes the full ASCII set, so it can carry SKUs, serial numbers, batch codes, location IDs, and mixed alphanumeric strings such as SKU-48812-A. Its high density means it also stays compact even with longer payloads.
Pick Code 128 when the barcode is for your own warehouse, asset tags, shipping labels, or a WMS integration — anywhere you control both the printer and the scanner and do not need a GS1 retail number.
- Warehouse & inventory labels
- Shipping and carrier labels
- Asset tagging and serial numbers
