Barcoding products for Shopify Fulfillment Network (SFN)

Shopify Fulfillment Network (SFN) relies on product barcodes to uniquely identify your products. Any products that arrive at SFN with unscannable barcodes will cost you preparation service fees. SFN accepts the following barcode types:

  • Universal Product Code (UPC) -12, -13, and -14
  • European Article Number (EAN)
  • International Standard Book Number (ISBN)
  • Fulfillment Network Stock Keeping Unit (FNSKU)
  • Amazon Standard Identification Number (ASIN)
  • Assigned by Shopify

To ensure that SFN can scan your barcodes, you need to do the following:

  • Add and manage barcodes using the SFN app.
  • Make sure that barcodes created from your Shopify admin are added using the SFN app.
  • Attach a barcode to every product being shipped to SFN.
  • Use an approved barcode number for each product variant.
  • Make sure each barcode is at least 1 inch (2.5 cm) tall and 1.5 inches (3.8 cm) wide.
  • Make sure that you don't add more than 5 barcodes to a variant. If you need to add more than 5 barcodes to a variant, then you'll need to reach out to support.
  • Make sure that you're not using custom barcodes as they aren't supported.
  • Print barcodes in black ink on light, nonreflective backgrounds.

Barcode requirements

Using barcode printers

You can print barcodes with a traditional printer or a dedicated label printer. Depending on the model, the printer can connect to your device by USB, Bluetooth, or Wi-Fi.

When you’re ready to print out barcodes, install and set up barcode printing software. The Dymo Label software lets you customize and print barcode labels from a desktop. You can also use Microsoft Word to generate and print barcodes.

If you need help with barcode printers and software, then refer to Shopify supported barcode printers.

Your barcodes should be at least .3 inches (.762 cm). When printing barcodes, use black ink or very dark ink. If you are adjusting the size of the barcode by zooming in or out to fit a physical label size, the barcode itself can be reduced by up to 80% and can be increased by up to 200%.

The background should be a white non-reflective background.

It is best practice to print a barcode number, or GTIN, below the barcode symbol. This allows SFN to confirm the correct barcode in case there is a discrepancy.

Barcoding single products

When barcoding single products, place the barcode label in a highly visible area. The barcode label should lie on a flat surface. You should also avoid attaching barcodes to corners, edges, or seams.

Barcoding SIOC products

SIOC (ships in own container) products are shipped by SFN in the packaging they are received in. If you have SIOC products, place the barcode in a clearly visible area on the outside of the container.

Barcoding sets

A set is a collection of individual products that are packaged and sold together. Sets need to be clearly marked with one of the following stickers:

  • sold a set
  • ready to ship
  • do not separate

This helps ensure that SFN does not break these products apart or open up their packaging.

When barcoding sets, make sure only one barcode is visible. If you are using transparent packaging for your sets, remove or cover any barcodes from products inside of the packaging.

Barcoding case packs

Case packed products are when sellable units are packaged together to save on space and costs. When sending case packs to SFN, remove any barcodes from the outside of the packaging.

This signals SFN receiving teams that the case pack isn't a set and it's safe to open the container and receive the individual sellable units. Each sellable unit on the inside of a case pack needs to have a barcode attached.

Assigning approved barcodes to each product variant

A barcode is used by systems to identify and track a product. Ensure every product you're shipping to SFN has an approved barcode number assigned in the admin.

Choosing a barcode type

Every product that you ship to SFN needs to have a barcode attached. Other than the barcodes you have selected for the product within SFN, all other visible barcodes must be removed or completed covered. This is extremely important to prevent mis-scans and mis-picks during fulfillment. 2D barcodes such as QR codes are not currently supported by SFN.

There are three options for attaching barcodes to products:

  • sticky barcode labels
  • hang tags with barcodes
  • printing the barcode directly on your product or product packaging
