Understanding when to use the right type of label is essential for smooth fulfillment and accurate tracking—especially when working with Amazon through AccelerList.
This guide explains the difference between FNSKU labels and MF (Merchant Fulfilled) ticketing labels, and when to use each.
🏷️ What is an FNSKU Label?
An FNSKU (Fulfillment Network SKU) is a unique barcode assigned by Amazon to your product for FBA (Fulfillment by Amazon).
Use FNSKU labels when:
You are sending inventory to Amazon (FBA shipments)
You want Amazon to track your items in their warehouse
You need to ensure your products are correctly identified as yours
👉 These labels are required before shipping items to Amazon fulfillment centers.
📦 What is an MF Ticketing Label?
An MF (Merchant Fulfilled) ticketing label is used for items you store and ship yourself (FBM).
These labels typically include:
SKU or MSKU
Product title or identifier
Price (optional)
Barcode for internal tracking
Use MF ticketing labels when:
You are fulfilling orders yourself (FBM)
You need to organize and track inventory locally
You want faster picking and packing workflows
👉 These labels are for your internal use and are not scanned by Amazon warehouses.
