Technical notes

A SKU (Stock Keeping Unit) is an internal stock code a business uses to tell its own products apart. It is not a global, registered number like GTIN/EAN/UPC; it is a company-specific identifier whose rules you set entirely yourself.

A good SKU scheme is consistent and readable: for example category abbreviation + variant + sequence number (like TSHIRT-RED-M-001). Meaningful but not overly long codes are easy for both humans and systems to manage; avoid spaces and non-ASCII characters.

SKUs must be unique; giving the same code to two different products causes inventory confusion. Check your generated list for clashes with the barcode duplicate finder.

If you want to turn a SKU into a barcode, Code 128 usually fits because it's alphanumeric; send the value to the barcode generator. But this barcode is for internal use; retail sale requires a registered GTIN.

Frequently asked questions

No. A SKU is your business's internal stock code; a GTIN is a globally unique item allocated by GS1. You define the SKU; you obtain a GTIN by applying.
