Find Amazon ASINs by barcode
Look up Amazon ASINs for products you don't yet sell, using UPC, EAN, GTIN, ISBN, or JAN codes.
If you want to co-list against products already in Amazon's catalog but only know them by barcode, this data source searches Amazon's public catalog and returns the matching ASIN for each identifier. It works for products your account does not sell yet — the existing Amazon Product Import datasources only return ASINs your account already lists.
The ASINs this data source finds are typically used as input for the Amazon Offer Creation export, which needs an existing ASIN to list an offer against.
Prerequisites
To use this data source, you need:
- An active Amazon account connection in Productsup.
- A list of the product identifiers you want to look up: UPC, EAN, GTIN, ISBN, or JAN codes.
- The identifiers must all be the same type. If you have a mix, for example some UPCs and some EANs, run this data source once per type.
Add the data source
Go to Data Sources from your site's main menu and select ADD DATA SOURCE.
Search for Amazon Catalog ASIN Search & Match, select Add, give it a name, and select Continue.
In Authentication, select an existing authentication or select Add New Authentication to connect your Amazon account via OAuth.
In Identifiers, enter your barcodes separated by #, for example 840132647045#840132676922.
In Identifier type, select the type all of your identifiers share: UPC, EAN, GTIN, ISBN, JAN, or MINSAN.
Caution
Amazon does not validate the identifier type you choose. If you select the wrong type, every identifier returns as unmatched instead of showing an error, so double-check this before your first run.
In Marketplace ID, select one or more marketplaces to search.
Optionally, set Max identifiers to cap how many barcodes this data source processes per run. The default is 10,000.
Select Save.
What you get back
Each run adds one row per identifier to your data, with the following columns:
| Column | Description |
|---|---|
| Input identifier | The barcode you searched for |
| ASIN | The matching Amazon ASIN, if found |
| Title, brand, product type | Basic product details from Amazon's catalog, to help you confirm the match |
| Match count | How many candidate ASINs Amazon returned for this identifier |
| Requires review | Set to true when a barcode returns no match or more than one candidate ASIN |
A barcode with zero matches still produces a row, with an empty ASIN and requires review set to true — it is never silently dropped.
Use the results
Rows with a single, clean match are ready to use as the ASIN for your Amazon Offer Creation export. Rows flagged requires review need a manual decision before you list an offer against them, since Amazon returned either no candidate or several possible matches.
Common issues
| Issue | Likely cause | What to do |
|---|---|---|
| All identifiers come back unmatched | Wrong identifier type selected | Confirm the barcode type and run the data source again |
| An identifier has multiple candidate ASINs | The barcode is shared across several catalog listings | Review the candidates manually and choose the correct ASIN |
| An identifier has zero matches | The product isn't in Amazon's catalog under this identifier, or the marketplace is wrong | Confirm the barcode and marketplace, or check with the brand for the correct identifier |
