How do you match your products to Amazon listings?
Look up each product's EAN or UPC on Amazon to find its ASIN, Amazon's product ID. Where there's no barcode, search Amazon by brand and model and confirm the match by title, attributes and image. Once you have the ASIN, you can track the product's price and every seller's offer over time.

ScrapeWise Amazon tools
Amazon plugins cost €0.15 per 1,000 calls and return EAN, brand, price and sellers.
After you have the ASIN
- Pick the offer to compare
- The Buy Box price, the lowest new price, or a specific seller; decide which matters for you.
- Track over time
- Amazon prices change often; daily checks catch promotions.
- Watch for variations
- Parent ASINs group sizes and colours; match the exact child ASIN.
When matches go wrong
- Multipacks
- A 3-pack listed under the same brand and name has a different ASIN and price.
- Marketplace differences
- The same product has different ASINs or offers on amazon.de and amazon.co.uk.
- Re-listed products
- Old ASINs can be merged or replaced; recheck matches regularly.
Frequently asked questions
What is an ASIN?
An ASIN (Amazon Standard Identification Number) is Amazon's 10-character ID for a product listing. Books use their ISBN instead.
How do I find an ASIN from an EAN?
Search Amazon for the EAN or UPC; most branded listings include it. Tools like ScrapeWise's search_amazon can do this in bulk.
Can one EAN have several ASINs?
Yes. Duplicate listings, bundles and marketplace differences can give one barcode several ASINs, so check title and pack size too.
Is there an official Amazon API for product matching?
Amazon's Creators API (replacing PA-API 5) gives affiliates catalogue data, and the Selling Partner API covers your own listings. Neither is designed for tracking all competitors' offers.
How do I compare every seller's price on Amazon?
Fetch the product's offers, not just the main price. ScrapeWise's get_amazon_product can return every seller's price for an ASIN.
