SKU
Pronunciation: SKYOO
Also written as: SKU — Stock Keeping Unit
A unique alphanumeric code assigned to a distinct product or product variant to facilitate inventory tracking and management.
Full Definition
Stock Keeping Unit (SKU) is a retailer- or warehouse-defined identifier used to track inventory at a granular level, differentiating products by attributes such as size, color, or packaging. Unlike barcodes, SKUs are internal codes that vary between organizations. In editorial contexts, SKU is always rendered in full capitals with no periods. The plural 'SKUs' does not take an apostrophe. Editors working on inventory reports or product catalogs should ensure consistent SKU formatting throughout the document.
Usage
Usage note: Always all-caps; no periods between letters. Plural is 'SKUs' (no apostrophe). Do not conflate with UPC or barcode, which are standardized external identifiers.
