Choose a stable order for brand, product family, variant attributes, and sequence. Keep that order across every channel so a warehouse label and a spreadsheet row describe the same thing.
Use short codes that a teammate can interpret without a private legend. Avoid spaces, punctuation that breaks imports, and attributes that change after the item is created.

The sequence is local to the batch. This free generator does not check your catalog or promise global uniqueness, so compare the output with existing records before importing.
SKU vs UPC, EAN, or barcode
A SKU is an internal identifier you design. A UPC, EAN, or GTIN is a standardized trade identifier issued under a formal system. A barcode is a machine-readable representation of data.
Do not invent a UPC or GTIN with this tool. Use the generated SKU inside your own inventory, order, and product-management workflows.
Rules for a scalable SKU system
Document the component order, allowed characters, abbreviations, and ownership of new codes. Never reuse an retired SKU for a different product.
Before bulk import, export a small test set and confirm leading zeros, case, delimiters, and spreadsheet formatting survive the target platform.
Questions, answered.
What does SKU stand for?
SKU means stock keeping unit: an internal identifier a business assigns to a sellable product or variant.
Are the generated SKUs guaranteed to be unique?
No. The generator is deterministic and does not inspect your catalog, so you must check the batch against existing identifiers.
Can I use these SKUs on Shopify or marketplaces?
Usually, yes, as internal variant identifiers. Confirm the destination platform’s length and character rules before a bulk import.
