# Manage ASINs

## Overview

An **ASIN** ( **Amazon Standard Identification Number**) is a unique identifier assigned to products listed on Amazon. It is a 10-character alphanumeric code you can find in the product detail page URL on Seller Central or in the product detail section. The **ASIN** is used to identify and track products in the Amazon catalog.

Once your product has an **ASIN**, Sellercloud can use it to match your SKUs with your Amazon listings to send accurate information, such as inventory and pricing. You will also be able to use the [Get Info from Amazon](https://descartessystems.aha.io/pages/7630832964864591781) functionality to avoid manual data entry.

## Assign ASINs to Products

You can add ASINs to products individually or in bulk. To bulk-assign ASINs to products, follow the steps to [Bulk Update Products](https://descartessystems.aha.io/pages/7630834039903362072) and fill out the ASIN column in the template you upload.

To manually assign an ASIN to a single product:

1. Go to a [Product Details](https://descartessystems.aha.io/pages/7630846719601169819) page.
2. Click **Toolbox** and select **Amazon Properties**.
3. Click **Edit**.
4. Update the **ASIN** field in the **General** section.
5. Click **Save**.

## Get ASIN

There are a couple of ways to get ASINs from Amazon.

### Find ASIN

To get the ASIN for a single product:

1. Go to a [Product Details](https://descartessystems.aha.io/pages/7630846719601169819) page.
2. Click **Toolbox** and select **Amazon Properties**.
3. Click **Actions** and select **Find Asin...**

### Get ASINs From UPCs

A single UPC can be assigned to multiple products. You may receive multiple ASINs for a single UPC following the steps below. In this case, you must manually check the ASINs to see which ASIN corresponds to the right product.

For this feature to work, the products you select must already have [UPCs assigned](https://descartessystems.aha.io/pages/7630846673564379841).

To get ASINs from UPCs in bulk:

1. Go to **Catalog** 
2. Find and select products.
3. Click the **Actions** menu.
4. Click **Get ASIN From UPC**.
5. Click the notification to access the **Queued Job**.

To get ASINs from UPCs via file upload:

1. Go to **Catalog > Tools > Find ASIN from UPC**.
2. Click the **Download Template** icon.
3. Fill the template with a list of UPCs under the **UPC** column.
4. Upload the file and click **Find ASIN**.

## Create a New ASIN

While the Amazon catalog is expansive, there may be some products you want to post that are new to the channel and require a new [ASIN](https://help.sellercloud.com/definitions/#asin) to be created. This happens often for private label items that are not sold by other merchants. In order to create a new ASIN through Sellercloud, you must configure your product’s categories and attributes. Once they are configured and you post the item on Amazon, a new ASIN will be generated. The ASIN will automatically be updated in Sellercloud as well.

To create a new ASIN:

1. Enable the following [Client Settings](https://descartessystems.aha.io/pages/7630835167106228692):
   - **Enable Amazon SP Listings API**
   - **Enable Amazon SP API Product Attributes**
   - **Enable Country Of Origin On Product Home Page**
2. Go to the [Product Details Page](https://descartessystems.aha.io/pages/7630846719601169819).
3. Click **Toolbox** and select **Amazon Properties**.
4. Click **Edit** to prepare the product for posting on Amazon. Amazon requires products to be listed with either a **UPC** or **ASIN**. In this case, you will have to enter the **UPC**.
5. In the **Listing Details** panel, click the icon to the right of **Configure Attributes**.
6. Select the product's **Category**.
7. Optionally, you can check **Show Required Attributes Only** to display only the attributes without which you are unable to post the product.
8. Populate the **List Values** fields for each attribute.
9. After completing the required attributes, click **Save & Validate** to validate your entries and check if any new fields are required.
10. Click **Actions** and select **Post Product On Amazon**.

## Block an ASIN

Amazon may limit listing certain products to approved merchants. To ensure compliance, you can prevent the accidental posting of restricted products with the **Blocked ASINs** feature in Sellercloud.

To block an ASIN:

1. Click **Settings** > **Marketplaces** > **Amazon** > **Block ASINs**.
2. On this page, you can see all your blocked ASINs. Using the icons in the top right corner, you'll be able to add, import, export, and download templates for ASINs you want to be blocked.
3. To block a new ASIN, use the **Add New ASIN** plus icon.
4. Enter the **ASIN** (not the ProductID) and click **Save**.

## ASIN Merge Audit

Sometimes, Amazon merges two ASINs when there are identical products on separate ASINs. The merge results in a deleted ASIN, which can cause multiple problems. Amazon notifies sellers when their listings have been merged. The Amazon ASIN Merge Audit allows you to apply a new ASIN to the product in Sellercloud.

To perform an Amazon ASIN merge audit:

1. Go to **Catalog** > **Amazon ASIN Merge Audit**.
2. Select a company. The grid will show all products with an ASIN that has since changed on Amazon.
3. Select the products to change and press the **Update Product ASIN to Match Amazon** icon.

4. The new ASIN will populate in the **ASIN** field in the product's **Amazon Properties** > **General** panel and on the [Product Details Page](https://descartessystems.aha.io/pages/7630846719601169819).
