How can the sellers update the attributes?

Sellers can edit individual ASINs or do a BULK upload of revised values through Seller Central. You can find below the steps for each:

Single ASIN attribute update:

  • Navigate to Manage Inventory under the Inventory tab on Seller Central
  • Search the ASIN and click Edit
  • This will open up a new tab
  • In the Vital Info section, fill Size Name and Size Map
  • Save changes

BULK Upload Process for Attribute Update:

  • Navigate to Add products via upload under the Inventory tab on Seller Central.
  • Download the inventory template titled Inventory files (at the bottom) or generate the required category template.
  • Download the category specific flat-file and fill SKU, Size name, Size map, MRP, update delete (fill Partial update). Save the file in text tab delimited format.
  • Navigate to Add products via upload under Inventory and then upload your inventory file.
  • Select file type as inventory file (default) and upload.

Should we update for all ASINs?

It is required that all SKUs/ASINs follow the same nomenclature as mentioned in FAQ 1 above.

What will happen if I don’t update?

For SKUs/ASINs that do not follow the nomenclature suggested in FAQ 1, Amazon will be updating at the back end in a scalable and systematic way.
