An Amazon product URL copied from the address bar routinely runs past 200 characters. Almost none of it identifies the product. The rest is search context, page position, session data and — if you arrived via someone's review — an affiliate tag that keeps earning them commission every time your link is clicked.
Paste it below to get the short canonical form: amazon.com/dp/PRODUCTID.
The only part that identifies a product is the ASIN — a ten-character code that appears after
/dp/. Everything else is optional.
| Parameter | What it does | Removed? |
|---|---|---|
/dp/B08N5WRWNW |
The ASIN, Amazon's product identifier. This is the only part that is actually required. | Kept |
tag |
Affiliate tag. Credits commission on any purchase to the account that owns it — including when you re-share the link. | Yes |
ref, ref_ |
Records the exact page element you clicked to arrive: search result position, carousel slot, recommendation strip. | Yes |
pd_rd_i, pd_rd_r, pd_rd_w, pd_rd_wg |
Recommendation-engine session tokens tying the visit to a specific browsing session. | Yes |
pf_rd_p, pf_rd_r |
Placement and request identifiers for merchandising slots. | Yes |
qid, sr, keywords, crid, sprefix |
Your search query, timestamp and result ranking — literally what you typed into the search box. | Yes |
th, psc |
Product variant selection state. | Yes |
Before
https://www.amazon.com/Some-Product-Name-Here/dp/B08N5WRWNW/ref=sr_1_3?crid=2M9K1LX8QW&keywords=wireless+headphones&qid=1718900000&sprefix=wireless+head%2Caps%2C212&sr=8-3&tag=someaffiliate-20
After
https://amazon.com/dp/B08N5WRWNW
Both URLs open the same product page. The second is 32 characters instead of 214, and it does not tell the recipient what you searched for to find it.
The keywords and crid parameters preserve your search query. Sending someone a
raw Amazon link shares your search terms along with the product, which is not always what you intend.
The tag parameter is a different problem. If you copied the link from a review site or a
YouTube description, that affiliate tag travels with it. Every person you forward it to is generating
commission for a third party, and Amazon's operating agreement is explicit that affiliate links should not
be shared in contexts the associate has not disclosed.
If you would rather do it by hand: look for /dp/ in the URL and take the ten characters that
follow it. That is your ASIN. https://amazon.com/dp/ plus those ten characters is a complete,
working product link. You can also find the ASIN listed in the product information table further down
any Amazon listing page.
Note that this shortening applies to amazon.com product pages. On regional domains such as
amazon.co.uk or amazon.de, the tool still strips the tracking parameters, and the
same /dp/ASIN pattern works if you build the short URL yourself.
ASIN stands for Amazon Standard Identification Number. It is the ten-character code after /dp/ in a product URL and it uniquely identifies that product on Amazon.
Yes. amazon.com/dp/ASIN is the canonical form of an Amazon product URL and opens the same page as the long version.
It means no affiliate commission is credited on purchases made through your cleaned copy of the link. If you want to support a creator, use their original link rather than a cleaned re-share.
a.co links are server-side redirects, so the destination is not visible in the URL itself. Open the link first, then clean the full URL you land on.
