Quick Examples
Understanding Barcode Requirements
🏷 One Barcode Per Variation
Each unique product variation (size, color, flavor, etc.) requires its own UPC or EAN barcode. A shirt in 3 sizes and 4 colors needs 12 separate barcodes.
📈 Calculate Variations
Multiply your variation options together. If you have 3 sizes x 4 colors x 2 materials = 24 unique products, each needing a barcode.
🏠 Retail Requirements
Major retailers like Amazon, Walmart, and Target require unique UPC/EAN codes for each product variation to track inventory accurately.
💰 Plan for Growth
Consider future product variations when purchasing barcodes. Buying in bulk saves money and ensures you have codes ready for new products.
