Shopify Packing Slips & UPCs: Why Your Barcode Isn't Printing (and What To Do)
Hey there, fellow store owners! Let's talk about something that might seem small but can cause big headaches in your fulfillment process: getting those crucial UPC codes or barcodes onto your Shopify packing slips. I've seen this come up quite a bit in the community, and a recent discussion really highlighted the frustration and the need for clear answers. It's a classic case of knowing the data exists in Shopify, but just not being able to access it exactly where you need it.
The Mystery of the Missing Barcode on Packing Slips
Picture this: you're shipping out orders, trying to be as efficient and error-free as possible. You rely on SKUs, but for ultimate accuracy, especially with similar products or tiny items, a UPC (Universal Product Code) or GTIN (Global Trade Item Number) is gold. It's right there in your product variant details in Shopify, so it should be simple to print on the packing slip, right? You'd think so!
Our friend TravelingBags, who kicked off this community thread, perfectly articulated the problem. They need their packing slips to show something like this:
Product Name: Magical Item to solve every problem v2.0
Product Description: Greatest thing you will ever buy !
SKU: I8ONE2 UPC: 123409876123
The logical step, as many of us would assume, is to simply add {{ line_item.barcode }} to the packing slip template. But here's the catch – as both Joeemmie_Donz and Jovan0209 confirmed in the thread, this variable isn't actually supported in Shopify's native packing slip templates. Even though the barcode data lives at the variant level, the system doesn't expose it to the packing slip Liquid object model.
Jovan0209 summed it up perfectly:
{{ line_item.barcode }}
...will simply not output any value. It's a bummer, because having both SKU and barcode would significantly reduce fulfillment errors and make life easier for anyone picking and packing orders, especially if you deal with:
- Products with very similar names or appearances.
- Small items where details can be easily missed.
- Inventory from multiple suppliers with varying internal SKUs but consistent UPCs.
So, What Can We Do About It? Two Main Paths Forward
While there isn't a magical one-click fix to get line_item.barcode directly on the default Shopify packing slip, the community discussion offered some valuable directions. Think of it as two paths: pushing for a native solution, or finding effective workarounds.
Path 1: Push for a Native Shopify Update (Feature Request!)
This is probably the most direct way to get what we all want in the long run. As Joeemmie_Donz and Jovan0209 both suggested, this is a prime candidate for a feature request. Why? Because the data already exists in Shopify at the variant level. Exposing it on the packing slip template seems like a relatively straightforward enhancement that would provide huge value to merchants.
How to Submit a Feature Request:
- Contact Shopify Support: The best way to get your voice heard is directly through Shopify Support. You can usually find their contact options (chat, email, phone) within your Shopify admin.
- Clearly Explain Your Use Case: Just like TravelingBags did, explain *why* you need this. Emphasize how it helps reduce fulfillment errors, improves efficiency, and adds a crucial layer of verification.
- Reference the Specific Variable: Mention
line_item.barcodeand that it's currently not exposed in the packing slip Liquid template. - Suggest It as an Enhancement: Frame it as a valuable improvement for all merchants. The more merchants who request this, the higher it climbs on the product team's priority list!
TravelingBags even posted a call to action: 
Please vote this up if you desire this access too. So, make your voice heard!
Path 2: Workarounds for Now (Get Creative!)
While we wait for Shopify to potentially add native support, there are definitely ways to tackle this issue. Jovan0209 laid out some excellent options:
Option A: Leverage Third-Party Order Management/Fulfillment Apps
Many robust third-party order management, picking, or packing apps offer much more control over your document templates. These apps often have their own Liquid-like templating systems or drag-and-drop editors that *do* expose barcode data for printing on packing slips, pick lists, or shipping labels. This can be a more involved solution, but if you're looking to streamline your entire fulfillment operation, it might be worth exploring an app that offers this level of customization.
Option B: Use Shopify's Free Order Printer App for Custom Templates
This is a fantastic native alternative that gives you a lot more flexibility than the default packing slip. The Shopify Order Printer app (free!) allows you to create custom templates for invoices, packing slips, and more. While it still operates within Shopify's Liquid environment, it often provides access to a broader set of order and line item properties. You might be able to craft a custom packing slip template here that pulls in the barcode information, potentially by using a different variable or a workaround like storing the barcode in a meta field that is accessible via Order Printer templates.
Option C: Creative Data Storage (Use with Caution!)
Jovan0209 also suggested, "Store barcode information in a location that is already accessible to packing slip templates (where operationally feasible)." This is less ideal, but if you're in a pinch and have very specific needs, you might temporarily store the UPC in another accessible field on the product variant, like the SKU field itself (if your SKUs are simple and don't clash) or a custom meta field that you've found a way to expose on the packing slip (though this often requires an app or more complex customization). This approach can get messy quickly, so it's usually considered a last resort.
Ultimately, getting both your SKU and UPC/barcode onto your packing slips is a solid strategy for error-proofing your fulfillment. It's a common need, and it's great to see the community discussing it openly. Don't be shy about submitting that feature request to Shopify, and in the meantime, explore those third-party apps or the versatile Order Printer app to get the job done!
