## Primary Purpose

The Barcodes tab assigns a barcode to the listing. Scanners and external systems use the barcode to identify and look up this listing.

<AccordionGroup>
  <Accordion title="One barcode per listing">
    The tab holds a single barcode value for the whole listing. The code can be any format — UPC, EAN, or a custom code used internally or by suppliers. Barcodes are not assigned per variant.
  </Accordion>

  <Accordion title="Fast lookup">
    Scanning the barcode resolves straight to the listing for quick lookup and order creation.
  </Accordion>

## Related Concepts

  <Accordion title="Stock Codes">
