Product link shapes: read the platform and item number
Direct search and manual requests use different address shapes. These examples explain the cleaner’s local rules, not whether a listing is available today.

ElectronicsThe highlighted item number identifies a listing within its platform. Tracking parameters can differ between copies; variant parameters may still matter to the option you intend to buy.
The four the search field reads
Pasteable, read on 2026-10-10
TaobaoSearch box
https://item.taobao.com/item.htm?spm=a1z10.3-c&id=648643962926
Query parameter. The spm tracking value in front of it differs between two copies of the same link, which is why string comparison finds no duplicates and item-number comparison finds plenty.
TmallSearch box
https://detail.tmall.com/item.htm?id=11223344&skuId=99887766
Same parameter as Taobao. A skuId may ride along; it names a variant, not a different product, so it is not part of the identity.
1688Search box
https://detail.1688.com/offer/771234567890.html
This example identifies the listing in the path. Reading only an id= query parameter would miss this form.
WeidianSearch box
https://weidian.com/item.html?itemID=5566778899&spider_token=ab12
Third spelling of the same idea. Copies of one Weidian link differ in capitalisation and in the trailing token.
The examples use different URL conventions. Check the host and the platform-specific item field rather than searching for any number in an address.
One detail that bites
Capitalisation is not consistent either. The same Weidian parameter appears as itemID, itemId and itemid depending on where the link was copied from, so matching has to ignore case.
Manual-request examples
Request only, named on the operator's own banner
JDRequest form
https://item.jd.com/100012345678.html
A real listing with a number in the path, and still a request: the operator names JD among the platforms its form covers rather than its search field.
YupooRequest form
https://x.yupoo.com/albums/123456
An album may contain multiple products or incomplete purchase details. Identify the exact item and confirm price, options and seller terms in a request.
XianyuRequest form
https://www.goofish.com/item?id=999888777
A second-hand marketplace. Check the selected item’s current availability, condition and return terms.
XiaohongshuRequest form
https://www.xiaohongshu.com/explore/abc123
A post may describe an item without providing enough details to buy it. Include the exact product and available seller information.
DewuRequest form
https://dewu.com/product/5566
Also written Poizon. Named on the operator's banner alongside the other four.
The older banner below names five platforms. Article 10112 read 2026-10-10 also names Zhuanzhuan, so the banner is not an exhaustive coverage list.
Worth noticing what this list is not: it is not a ranking of platforms and it says nothing about which has better goods. It is a statement about parsing.
Ways a saved address can become unusable
It was trimmed
Tidied up by deleting the query string, which took the item number with it. What opens now is a shop front page.
It was shortened
A shortened address may hide the platform and item number. Open it yourself and copy the resolved product URL; this local tool does not follow redirects.
The listing moved
A seller can remove a listing or publish a replacement with a different number. Recheck the original seller page.
It was never a listing
An album, a post, a search result page. These are worth keeping and have to go by form.
Only the first is preventable by habit: copy the whole address, every time. The rest are reasons to save the shop name and the title alongside the link, which costs a column and solves three problems.
Questions this page gets
Can I just delete everything after the question mark
Keep the full source link. Taobao, Tmall and Weidian use query parameters for item identity, while 1688 usually puts the listing number in the path. Other parameters can still matter for selected variants or link behaviour.
Two links look different but are the same product
Matching platform and listing numbers can reveal copies with different tracking parameters. This catches the supported numeric formats; it does not resolve short links or identify a product shared across different sellers.
What if an address has no number anywhere in it
The cleaner cannot compare that address by product number. Open it yourself and confirm the listing or request details. An album, post or short link may need more information before it can be purchased.
Does a variant id make it a different product
A variant ID identifies an option within a listing. Two matching listing numbers can still mean different intended colours or sizes, so review those details before omitting a flagged duplicate.
