Short answer: 1 barcode for the 100 pieces

Alright, so the deal with barcodes and Amazon selling is that you typically only need one barcode for a batch of identical products. So in your case, since you have 100 pieces of the same product with the same color and sizes, you only need one UPC barcode to cover the entire lot.

Why you only need one barcode

The reason for this is that the barcode serves as a unique identifier for the product itself, not for each individual item. So as long as all 100 pieces are exactly the same, they can all be assigned the same barcode. This makes things a lot easier for both you and Amazon, as you don’t have to manage individual barcodes for each item.

What to do if the products have variations

Now, if your 100 pieces have variations in color or size, that’s when things get a bit more complicated. In that case, you would need multiple barcodes to distinguish between the different variations. Each different color or size would require its own unique barcode to accurately track inventory and sales.

How to create and assign barcodes

To create and assign a barcode for your batch of 100 pieces, you can either generate your own UPC barcode or purchase one from a reputable barcode provider. Once you have the barcode, you can assign it to your products in your Amazon seller account. Amazon will then use this barcode to track and manage your inventory.

Final thoughts

In conclusion, you only need one UPC barcode for your 100 pieces of the same product. Make sure to accurately assign the barcode to your products in your Amazon seller account to keep your inventory organized and easily trackable. And if you have variations in your products, be sure to assign unique barcodes to each variation to avoid any confusion. Happy selling!
