Frequently asked questions

The ASIN (Amazon Standard Identification Number) is the unique identifier Amazon assigns to every product. Paste an ASIN into Komparzon and you get that exact product's price across the 7 European marketplaces. It is the most reliable way to compare without mixing up two variants.

Where do I find a product's ASIN?

In the URL, right after /dp/ (for example /dp/B07KP2FFVM), or in the “Product details” section at the bottom of the page. It is always a 10-character alphanumeric string.

Does every Amazon product have an ASIN?

Yes. Each variant (size, colour, capacity) has its own ASIN. For books, the ASIN generally matches the ISBN-10.

Is the ASIN the same on Amazon.fr, Amazon.de and Amazon.co.uk?

Yes — for a given product the ASIN is shared across Amazon sites. That is exactly what lets Komparzon query 7 marketplaces at once from a single reference.

What if the ASIN isn't sold in every country?

Komparzon marks the marketplaces where the ASIN is unavailable. You see at a glance which countries carry the product, and at what price.

How do I paste an ASIN into Komparzon?

In the search bar, enter the ASIN on its own (10 characters) or paste the full Amazon URL: Komparzon extracts the ASIN automatically.
