### **Fast Facts**

**Purpose**  
Identify bag styles, colors, sizes and pack quantities during storage, order picking and sale.

**FNSKU labels**  
Amazon uses FNSKU labels to identify inventory for a particular seller within its fulfillment network. Check your listing’s barcode requirements before printing. 

**UPC and EAN**  
These retail barcode formats carry product identification numbers that checkout systems and supply-chain scanners can read. 

**Internal SKU labels**  
A stock keeping unit, or SKU, is your own product reference. Print it as readable text, with a compatible barcode if your inventory system uses one.

**Placement**  
Labels can sit on individual packaging or hangtags. Choose a smooth area that keeps the code flat and visible.

**Product matching**  
Match each label to the correct bag variant and selling unit. A single bag and a multipack need the appropriate identification.

**Why choose it?**  
Identification labels help your team tell similar bags apart without opening every package. They support stock counts, order picking and repeat orders, especially when one design comes in several colors or sizes. A brand label tells buyers who made the product; an identification label tells staff which product they have.

**Things to consider**  
Choose the code your retailer, marketplace or warehouse requires; an internal SKU does not replace a required retail barcode. Wrinkles, poor printing and folds can interrupt scanning. Keep clear space around the code and test a printed sample on the final packaging. For Amazon shipments that require FNSKU labels, follow its rules for covering other barcodes, including exceptions for serial numbers and Transparency authentication codes. 

**Customization options**  
Options include label dimensions, paper or synthetic materials, adhesive type, placement and readable details such as color, size or pack quantity. Keep branding outside the barcode’s clear space. Supply the correct product codes and Amazon-generated label files where applicable. We’ll need to confirm label materials, printing and application options for your order.

**Best suited for**  
Identification labels suit individually packed drawstring bags, retail pouches and bag multipacks that need stock tracking or checkout scanning. For mesh or textured fabric, a smooth packaging surface or hangtag provides a more practical position than sticking a label directly onto the bag.
