1. Dynamic Column Mapping

Map the barcode field directly to the corresponding column header name or index in your feed file to import unique barcodes for each variant.

2. Fixed Barcode Value

If your feed file does not have a dedicated barcode column, enter a static fixed value that applies uniformly across all mapped items.

Key Rules & Technical Details

• Supported Formats: Accepts standard numeric and alphanumeric barcode formats including UPC, EAN, ISBN, and GTIN.
• Fixed Value Override: When set to a fixed value, every variant processed by the feed receive the exact specified barcode value.

Troubleshooting Steps

• Issue: Barcodes are not updating on Shopify → Solution: Confirm that the correct column name or index is selected in Step 2: Field Mapping, or verify that your fixed value is saved.
• Issue: Barcode update fails due to invalid characters → Solution: Remove special characters, spaces, or symbols from your feed file or fixed value field.
