Amazon ASIN Extractor & Finder
Paste any Amazon product URL — long, short, mobile, or shortened — and this free ASIN tool pulls out (or looks up) the ASIN and builds a clean, canonical product link for every Amazon marketplace.
What is an Amazon ASIN?
An ASIN (Amazon Standard Identification Number) is a 10-character alphanumeric code Amazon assigns to every product in its catalogue. Almost all non-book ASINs start with B0. For books, the ASIN is the same as the 10-digit ISBN. The ASIN is what makes a product link canonical — strip everything else from a long Amazon URL and the /dp/<ASIN> path alone still works.

Why marketplace-specific URLs matter
The same ASIN often exists across multiple Amazon stores, but each marketplace has its own price, stock, reviews, and shipping options. A canonical URL like amazon.co.uk/dp/B08N5WRWNW sends UK shoppers to the listing that will actually deliver to them. If you're an affiliate, this is also where your commission lives — a US tag ending in -20 earns nothing on amazon.co.uk. Once you have the ASIN, open the country-specific generator to add the correct tag for that store.
Amazon ASIN FAQ
What is an Amazon ASIN?
ASIN stands for Amazon Standard Identification Number. It is a 10-character alphanumeric code that uniquely identifies a product across Amazon. Most ASINs start with "B0" for non-book products. For books, the ASIN is identical to the 10-digit ISBN.
Where do I find the ASIN in an Amazon URL?
The ASIN typically appears after /dp/ or /gp/product/ in the URL. For example, in amazon.com/dp/B08N5WRWNW the ASIN is B08N5WRWNW. This extractor handles every common URL format including mobile, shortened, and search-result links.
Is the same ASIN valid on amazon.co.uk, amazon.de, and other Amazon stores?
Usually yes for products listed in multiple marketplaces, but not always. Amazon maintains separate catalogues per region, so a US ASIN may not exist on amazon.co.jp. Always click through the generated link to confirm the listing is live before sharing it with international audiences.
Will swapping the domain still earn me a commission?
Only if you append the matching regional Associates tag for that marketplace. A US tag ending in -20 will not pay on amazon.co.uk. You need a -21 tag for the UK and EU stores, and -22 for Japan. The country-specific generators linked below add the correct tag for each marketplace.
