Barcode Formats for Inventory and Warehouse Operations

Selecting the right barcode symbology is critical for warehouse efficiency. Code 128 is the industry standard for inventory labels - it encodes the full ASCII character set in a compact format, making it ideal for part numbers, serial numbers, and location labels.

Code 39 remains common in government and defense applications where legacy compatibility is required. UPC-A and EAN-13 are mandatory for retail point-of-sale scanning. ITF-14 is the standard for outer carton and pallet labeling in distribution.

QR codes are increasingly adopted in warehouse environments for encoding multiple data points in a single scan - part number, lot, and expiration date in one label.
