Deep discounts on current, in demand products from unknown sellers are the single strongest counterfeit signal a shopper can read without any expertise. The checks that follow it are quick: seller age and history, whether the discount exists anywhere authorised, stock depth on a supposedly scarce item, and dispatch origin versus the seller's stated location.
An authorised seller list is a verification tool, and like every verification tool it decays. It works when it is current, when product pages link to it, and when delisted sellers are removed promptly. A stale list that still names a seller the brand dropped is worse than no list, because it lends the brand's authority to the exact sellers buyers are trying to avoid.
A buyer who suspects a listing checks the list for one thing: is this seller on it. That check takes seconds when the list is searchable by seller name and linked from the product pages the buyer is already reading. Every extra step, a list buried in a corporate page, a PDF, a form to request access, cuts the number of buyers who finish the check.
The list also protects legitimate sellers. An authorised seller who is not listed loses sales to suspicion, and will say so, which makes resellers the list's most reliable accuracy check if the brand gives them a way to report errors. Treat those reports as free auditing, not as complaints.
Assign the list an owner and a review cycle, monthly for fast moving catalogues. Add sellers when authorisation is signed, remove them the day authorisation ends, and date the list so buyers can see it is alive. When a seller is removed for counterfeiting, the removal is the point: a list that never shrinks is a list nobody is policing.
Link the list from the places suspicion arises: product pages, the brand's marketplace storefront if it has one, and the answer the support team gives when a buyer asks if a seller is genuine. A list that support does not know about will not be used, however current it is.
A list verifies sellers, not items. An authorised seller can still be impersonated by a copied storefront using the same name and photographs, which is why the check should include the seller's actual storefront link, not just the name. Buyers should navigate from the list to the store, not from a search result to a similar name.
Pair the list with pattern reporting. When buyers report fakes, the reports show which brands and products counterfeiters are copying this month, and the list's warnings can name the current impersonation patterns. The list answers is this seller authorised; the reports answer what the fakes look like now. Both halves are needed.

Linked from the product pages shoppers actually land on, searchable by seller name, and dated so buyers can see it is current. A list buried in a corporate section gets checked by almost nobody.
On every authorisation change, with a monthly review as the floor. Remove sellers the day authorisation ends; a stale list that names dropped sellers lends them the brand's authority.
Yes, which is why the list should link to the real storefronts. Buyers should click through from the list rather than trusting a similar name in search results.
Treat the report as free auditing. Authorised sellers who cannot be found on the list lose sales, so their corrections are usually prompt and accurate. Verify, add them, and thank the reporter.
