How to create a SKU naming convention
Choose a small set of product attributes that help your team identify an item without opening a product record. Start broad with a brand, department, or category code, then move toward the product and its variant details. Use the same segment order everywhere.
SKU versus UPC, EAN, or barcode
A SKU is an internal identifier created by your business. UPC and EAN numbers are standardized identifiers assigned through official systems. A barcode is the machine-readable representation of a value. Generating a SKU does not create an official UPC or EAN.
Can Shopify variants share a SKU?
Each Shopify product variant should normally have a unique SKU. Duplicate values make inventory reporting, fulfillment, integrations, and marketplace synchronization harder to trust.
How many characters should a SKU contain?
There is no universal perfect length. Use the shortest structure that remains understandable and leaves room for future products. Consistency matters more than squeezing every product detail into the code.
