What is Code 128 for Inventory?
Code 128 is ideal for inventory management because it encodes alphanumeric SKU codes - unlike numeric-only barcodes. Warehouse staff scan these barcodes at receiving, put-away, picking and cycle-count to keep stock levels accurate. Because SKUs often contain letters and dashes (like WH-1001-A), Code 128's full ASCII support makes it the default choice for inventory systems.
Common Uses for Code 128 for Inventory
- Printing SKU labels for stock keeping units
- Labeling bins and shelf locations for put-away
- Cycle counting with barcode scanning guns
- Marking raw materials and work-in-progress parts
Frequently Asked Questions
Can Code 128 encode letters and numbers in SKUs?
Yes. Code 128 supports the full ASCII set, so SKUs like WH-1001-A or INV/B-22 scan correctly. Numeric-only codes like EAN-13 cannot encode letters.
What makes a good inventory barcode label?
A readable human SKU, a clean Code 128 barcode with quiet space around it, and a durable label that survives handling.
Do inventory barcodes need a check digit?
Code 128 has a built-in check character, so the barcode is self-validating. You do not need to calculate anything manually.
Can I print a full sheet of SKU barcodes?
Yes, paste all your SKUs (one per line) and print them on a single sheet with this tool.
