SKUs

Look up the merchant SKUs behind an enrolled ASIN.

list_asin_skus

Lists the merchant SKUs behind an enrolled ASIN — the seller's own inventory identifiers, as opposed to Amazon's ASIN. An ASIN can have several SKUs (for example a second, merchant-fulfilled SKU on the same product, or the same SKU text under different seller accounts), and this tool shows them all with their status and fulfillment channel.

When it's used

Reach for this when you need to map an ASIN to the SKUs in your Seller Central inventory: preparing a listing fix file, checking whether a SKU is still active, or spotting twin SKUs on the same product. The assistant typically finds the ASIN first via Search ASINs or Listing Issues, then uses this tool to get the SKU side.

What you can ask

"What are the SKUs behind ASIN B07XYZ1234 on Amazon US?"

"Is there a second SKU on this ASIN?"

"Which of these ASINs have inactive SKUs?"

Parameters

Parameter	Required	Description
organization_id	Yes	Detected automatically from your login.
marketplace_id	Yes	The marketplace the ASIN belongs to (see the Tools page for IDs).
asin	Yes	The 10-character Amazon ASIN.

What you get back

One row per SKU: sku, seller_account_id (the Amazon seller account it belongs to), status (active, inactive, incomplete, or removed), fulfillment_channel (amazon or merchant, empty when unknown), and title (the SKU's own listing title).

A SKU references exactly one ASIN, but an ASIN can carry several SKUs — including the same SKU text under different seller accounts. A SKU is therefore identified by the combination of sku, seller_account_id, and marketplace.
