Many sellers need a place to store and send product barcodes (UPC/GTIN) when crosslisting and syncing listings across channels.

Adding a UPC/GTIN field would help ensure your listings meet marketplace and ad-feed requirements—and reduce errors when updating existing posts.

What this would enable

• Enter and save a product’s UPC or GTIN directly in your listing/product details.

• Support both formats:

  • UPC (12 digits)

  • GTIN (14 digits)

• Send UPC/GTIN to key channels where it’s required or strongly recommended, including:

  • Shopify

  • eBay

  • Google Shopping

  • Bing Shopping

• More reliable updates: keep UPC/GTIN consistent when updating an existing post (not just when relisting), since some users report issues where updates behave inconsistently across listings.

Why it matters

• Helps listings qualify for more placements and better matching in shopping feeds.

• Reduces manual fixes and rework when a channel requires a valid barcode.

• Keeps product data consistent across platforms as you edit and update listings over time.
