  1. 1

    Enter Your Amazon ASIN

  2. 2

    Select Your Marketplace

    Choose the Amazon marketplace where the product is listed (Amazon.com, Amazon.co.uk, Amazon.de, etc.). This ensures you get the correct UPC for that region.

  3. 3

    Click Convert

    Click the Convert button. The tool will instantly search Amazon's catalog and find the matching UPC, EAN, and GTIN codes for that ASIN.

  4. 4

    View and Use Results

    The tool displays the matching UPC, EAN, and GTIN. Copy the UPC to use in your supplier matching, inventory management, or product research workflows.

ASIN vs UPC vs EAN

An ASIN is Amazon's own catalog ID. A UPC or EAN is the manufacturer's barcode that every retailer and supplier uses. The ASIN to UPC converter links the two.

Attribute ASIN UPC EAN
Format 10 letters and digits 12 digits 13 digits
Assigned by Amazon GS1 US GS1 member organizations
Where it works Amazon only US and Canada retail Europe and worldwide retail
Example B00U26V4VQ 841710196726 0841710196726
Sellers use it for Research, pricing, listing Supplier file matching International supplier matching

A UPC becomes an EAN when you add a leading zero, so 841710196726 and 0841710196726 are the same product. Need the other direction? Use the UPC to ASIN converter or the EAN to ASIN converter.

Why Convert ASIN to UPC?

Amazon works with ASINs, suppliers work with barcodes. Converting ASIN to UPC connects an Amazon listing to the product you can actually buy.

Match Amazon listings to suppliers

Suppliers list products by UPC, not ASIN. Get the UPC of an Amazon listing and search for it in supplier and distributor catalogs.

Confirm the exact product

One product can have several ASINs for multipacks, bundles, or variations. The UPC confirms which item the supplier actually ships.

Avoid listing mismatches

When the ASIN and the UPC agree, you do not attach your offer to the wrong listing — a common cause of returns and suppressed listings.

Spot duplicate listings

Several ASINs can share one UPC. Converting both ways shows duplicates and merged listings, so you sell against the best one.

Check authenticity

Tie an ASIN back to the manufacturer's barcode before you buy inventory, so the product you order matches the listing.

Prepare bulk sourcing

Convert a list of ASINs to UPCs, then upload it to Price List Analyzer to calculate profit, ROI, fees, and restrictions in one pass.

Frequently Asked Questions

What is an ASIN?
ASIN (Amazon Standard Identification Number) is a unique 10-character alphanumeric code Amazon assigns to products in its catalog. Every product on Amazon has an ASIN, making it the primary identifier for listing, searching, and tracking products on the platform.
What is a UPC?
UPC (Universal Product Code) is a 12-digit barcode standard used globally to identify retail products. Manufacturers assign UPCs to products. The UPC is the 'true' product identifier across all retailers and suppliers.
Why would an ASIN have multiple UPCs?
A single Amazon ASIN can sometimes map to multiple UPCs if: The ASIN represents a multipack or bundle (which may have its own UPC), the product is sold in different conditions (new vs. used), Amazon lists marketplace variations separately, or the product has regional UPC variations.
What other identifiers can I get besides UPC?
Besides UPC, the converter returns: EAN (European Article Number) - 13 digits, used primarily in Europe; GTIN (Global Trade Item Number) - the parent standard for UPC and EAN; and ISBN - for books (when applicable).
How does the bulk ASIN to UPC converter work?
The bulk ASIN to UPC converter lets you convert multiple ASINs to UPC or EAN codes at once. Simply upload an XLSX or XLS file, or paste your ASIN list, and get export-ready results in seconds.
Can I convert ASINs to both UPC and EAN?
Yes. The tool supports ASIN to UPC, EAN, and ISBN conversions — ideal for suppliers and Amazon sellers managing large product catalogs.
Who should use the bulk ASIN converter?

Is the bulk ASIN converter free?

What should I do if the ASIN doesn't have a matching UPC?
