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.
To ensure that SFN can scan your barcodes, you need to do the following:
- Use a unique barcode number for each product variant.
- Attach a barcode to every product being shipped to SFN.
- Print barcodes in black ink on light, nonreflective backgrounds.
- Make sure each barcode is at least 1 inch (2.5 cm) tall and 1.5 inches (3.8 cm) wide.
Assigning unique barcodes to each product variant
A barcode is used by systems to identify and track a product. Ensure every product you are shipping to SFN has a unique barcode number assigned in the admin.
Changing your barcode after submitting an inbound transfer can lead to processing delays.
Choosing a barcode type
Every product that you ship to SFN needs to have a barcode attached. 1D barcodes, including UPC, EAN, Code 39 and Code 128, are all acceptable formats. 2D barcodes like 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
If you need help choosing a barcode type for your business needs, then refer to Using barcodes for your products.
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.
Printing scannable barcodes
Your barcodes should be at least 1.5 inches (3.8 cm) wide by 1 inch (2.5 cm) tall. When printing barcodes, use black ink or very dark ink. 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, 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.
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.
