# 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](/autopilot-mcp/tools/search-asins.md) or [Listing Issues](/autopilot-mcp/tools/list-listing-issues.md), 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](/autopilot-mcp/tools.md#identifiers) 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).

{% hint style="info" %}
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.
