A barcode for shoes is the UPC printed on the shoebox label. It’s a 12-digit Global Trade Item Number (GTIN-12) that identifies one exact product: one style, in one color, in one size. Retailers scan it to receive stock, count inventory and ring up sales, and brands license the numbers from GS1 US. Every size, width and color of a shoe needs its own barcode.
The barcode doesn’t contain the shoe’s description. It’s a lookup key, and the retailer’s system matches the number to the style, color and size stored in its product database. That’s why the same scan works at any store whose database carries that product.
What Information Is on a Shoe Box Barcode Label?
A typical shoebox end label combines human-readable details with the scannable code. The details help staff find the right box on a shelf. The barcode is what the point-of-sale and inventory systems read.
| Label element | What it tells you | Read by |
|---|---|---|
| UPC barcode (GTIN-12) | The unique product number for that style, color and size | Scanners at receiving, checkout and returns |
| Style or article number | The brand’s model code, shared by every size of that shoe | Staff and buyers |
| Color code and name | The specific colorway | Staff and shoppers |
| Size (often US, UK, EU and cm) | The size, sometimes with width | Staff and shoppers |
| Country of manufacture | Where the pair was made | Customs and compliance |
If two boxes have the same style number but different UPCs, they’re different sizes or colors of the same shoe. That’s the detail that keeps a size 9 from being sold as a size 10 in the inventory count.
How Do You Get Barcodes for Shoes?
UPC numbers come from GS1 US, the standards organization that administers them in the United States. GS1 US offers two routes: a single GTIN for a business with only a handful of products, or a GS1 Company Prefix that lets a growing brand create many barcodes from its own block of numbers.
The rule that matters for footwear is that each variation needs its own number. GS1 US uses a T-shirt in three sizes and three colors as its example, and that shirt needs nine barcodes. Shoes multiply quickly. One style in ten sizes, two widths and three colors needs 60 GTINs, so most footwear brands are better off with a Company Prefix than with single numbers.
- List every variation of each style: size, width and color.
- License numbers from GS1 US, either single GTINs or a Company Prefix sized to your count.
- Assign a GTIN to each variation and record it with the style, color and size in your product list.
- Generate and print the barcode images on your box labels, using the UPC-A symbol for retail.
- Share the data with each retailer or marketplace so their system recognizes your numbers.
Many retailers and online marketplaces check product identifiers against GS1 records. Numbers licensed to your own company are the safest way to avoid rejected listings.
What’s the Difference Between a UPC, a SKU and a QR Code on Shoes?
These three codes do different jobs, and many shoe businesses use all of them.
| Code | Who assigns it | What it identifies | Main use |
|---|---|---|---|
| UPC (GTIN-12) | The brand, from numbers licensed through GS1 | One product variation, worldwide | Retail checkout, wholesale, marketplaces |
| SKU | Each retailer or seller, internally | A product in that seller’s own system | Internal inventory and bin locations |
| QR code | Anyone | Usually a web link or data string | Care instructions, authenticity checks, marketing |
A UPC holds only its 12 digits. A QR code can hold far more data, such as a link to a fit guide or a product registration page, but standard retail checkouts are built around the UPC. QR codes add to the UPC. They don’t replace it.
How Do Shoe Retailers Use Barcodes?
The same 12 digits get scanned at almost every step a pair of shoes takes through a store or warehouse:
- Receiving: scanning each carton as it arrives updates stock levels and catches shipments that don’t match the purchase order.
- Inventory counts: handheld scanners count boxes by exact size and color, which a manual count of identical-looking boxes often gets wrong.
- Checkout: a scan pulls the right price and size from the database, so the cashier doesn’t have to key in style codes.
- Returns: scanning a returned box confirms it’s the same product, size and color that was sold.
- Online order picking: scanning the box before packing confirms the picker grabbed the size the customer ordered.
Small sellers don’t need an enterprise system to get these benefits. A USB or Bluetooth scanner and inventory software that accepts GTINs cover most of them. Start with your fastest-selling styles and place labels in the same spot on every box.
How Should You Handle Shoe Barcodes When Shipping?
A shoebox UPC and a shipping barcode are separate systems. The UPC identifies the product. The tracking barcode on a USPS, UPS or FedEx label identifies the package, and carrier scanners read that one. Keeping them apart avoids misroutes:
- Ship the shoebox inside an outer box. It protects the shoebox, which is often part of the product’s value for collectors and resellers, and hides the retail barcode from carrier scanners.
- Cover old barcodes when reusing a box. USPS asks shippers to black out or cover all old labels, logos and barcodes on reused boxes.
- Put the shipping label on the largest flat side with the barcode fully visible and not wrapped around an edge.
Once the package is moving, the tracking number is the code that matters. Our UPS tracking guide explains each scan event, and our FedEx shipping hub covers that carrier’s tracking and services.

Frequently Asked Questions
Does every shoe size need a different barcode?
Yes. GS1 US requires a unique barcode for each variation of a product, so every size, width and color of a shoe gets its own GTIN. GS1’s own example is a T-shirt in three sizes and three colors, which needs nine barcodes. One shoe style in ten sizes and three colors needs 30.
What do the numbers on a shoe barcode mean?
A shoe UPC is a 12-digit GTIN. The first digits are the brand’s GS1 Company Prefix, the next digits are the product number the brand assigned, and the last digit is a check digit that lets scanners catch misreads. The barcode doesn’t spell out the size or color: the retailer’s database supplies those when it’s scanned.
Can I make my own barcodes for shoes?
You can print barcode images yourself, but the numbers inside them should be licensed to your company through GS1 US if you plan to sell through retailers or marketplaces. Many of them check identifiers against GS1 records. For internal tracking only, a seller can use its own SKU barcodes instead.
Can you scan a shoe box barcode to check if shoes are real?
Not reliably. A UPC only identifies the product listing, and a counterfeit box can carry a copied UPC that scans normally. Some brands add QR codes or NFC tags that link to their own verification, which is more useful. A matching barcode on its own doesn’t prove the shoes are authentic.
