Say we are prepping an Amazon shipment that contains 30 boxes shipping via small carrier (UPS). Note we are using UPC to identify the products, not FNSKU.

• 20 boxes are single-unit master packs. Each box contains 1 single unit. The box itself has a UPC barcode sticker. These boxes will reship to the end customer as-is, and will not be opened by Amazon.
• 10 boxes are multi-unit master packs containing several identical units, each barcoded separately. The master pack box contains an SCC14 barcode representing the case pack. The inner boxes contain the UPC barcodes. Amazon will open the master pack; the sellable units are contained within.

Questions:

1. Should we cover the UPC barcode on the 20 single-unit master packs with the Amazon shipment labels, or leave the UPC barcodes visible so their systems can identify the product?
2. Should we cover the SCC14 barcode on the 10 multi-unit master packs with the Amazon shipment labels? This SCC14 barcode is not an identifier in Amazon's system, the UPCs within are.
3. What happens if we leave either UPC/SCC14 barcode uncovered?

I need Amazon support on here for this issue.

I have uploaded my listings from Amazon UK to my US account and Amazon US has blocked one of the listings as they say they do not recognise the GTIN.

This listing uses my first GTIN 13 from my GS1 number bank and is also the same as the Global Location Number on my GS1 certificate.

Seller Support has continuously stated that the GTIN number is not valid and cannot be the same as a GLN.

This GTIN number has been used for the last 5 years in Amazon UK.

I have also contacted GS1 UK, who provided information to state that the GLN on my GS1 certificate will always be the first GTIN in my number bank, and it is a valid GTIN13 that scans at the point of sale. GS1 UK advised to send a screenshot of their email and to state that GS1 UK are confirming this.

Seller support is still refusing this and continues to state that a GTIN number cannot be the same as a GLN, regardless of proof of 5 years of operating on Amazon UK and direct information from GS1 UK.

I need Amazon to intervene as this makes zero sense. You require that we utilise GS1 barcodes, which I have done for 5 years with no issues in Amazon UK and then proceed to ignore direct information from the same GS1 organisation that you requested us to use for the barcodes.

The Case IDs are 16961258741 and 16989475461

I've seen similar discussions, but most asking if UPC is required and not the other way around. I've also seen some conflicting information outside of the forums, so I just want to put this out there, thanks in advance for any input.

We have completed Brand Registry for our company, and have a UPC from GS1 printed directly on our product. It's private label product, created by us, so there will not be any others selling with this same UPC.

Is the FKSKU, ASIN, (or any other labeling) required to be added? The product is setup as FBA, and when creating the shipping instructions the Information/Action is 'Prep not required / Manufacturer barcode'.

I think we're good with just the UPC, but I keep seeing other posts indicating that FNSKU is required.

Much thanks.
