Electronics often come in models, capacities and colors. Here’s how to barcode them without confusion.
Model and variant codes
A charger in two colors, or a device in two capacities, are distinct products — assign a unique barcode to each.
Marketplaces treat each variant separately.
Barcode vs serial number
A GTIN identifies the product model; a serial number identifies one specific unit for warranty and tracking. You may use both.
Don’t confuse the two — the barcode is the catalog identifier.
Retailer expectations
Most retail and online channels want a valid GTIN per variant. Provide genuine, unique numbers to list cleanly.
Keep a model-to-barcode map as your range grows.
