A verified purchase is a label attached to a customer review to show that the platform hosting the review has matched it to a transaction on its own records: the reviewer's account bought the product, through that store, at a price available to ordinary shoppers. Amazon is the best-known user of the badge, which appears as "Verified Purchase" beside a review. The label exists because anyone with an account can usually write a review, and readers need some way to separate people who handed over money from those who did not - competitors, friends of the seller, paid writers or people who never touched the product.

How the badge is assigned

The check happens when a review is submitted. The platform looks up the reviewer's order history for the product being reviewed. If a matching order exists, the review is eligible for the label. On Amazon, two further conditions apply. According to Amazon's trust and safety site, the company confirms that the item was bought on Amazon and that the price paid was one available to most Amazon shoppers. A product received free, or at a steep markdown offered only to a small group, does not earn the badge even if an order exists.

Reviews without a matching order are not banned. Amazon allows customers to review items bought elsewhere or received as gifts, provided the account meets a minimum spending threshold, which varies by country, paid with a credit or debit card on file, according to the company. Those reviews simply carry no badge.

The badge feeds into two further systems. The first is the star rating. Since June 2015, Amazon has calculated a product's overall rating using a machine-learned model rather than a simple average. According to GeekWire's report on the change, the model gives more weight to newer reviews, to reviews other customers rated as helpful, and to verified purchases. The second is review ranking, the order in which reviews appear on a product page, which uses similar signals.

Where several product variations share a parent listing, the reviews are pooled across them. That pooling is now narrowing. Amazon announced on January 7, 2026 that it would stop sharing reviews across variations with significant functional differences, with a rollout by category from February 12 to May 31, 2026. Eligibility depends on the variation theme attribute, and Amazon added a per-variation eligibility check to Seller Assistant in April 2026.

Who operates it

On a marketplace, the operator alone assigns the badge, because only it holds the order data. Sellers have no direct control over it. Third-party review platforms work differently. Google Customer Reviews, which replaced Google Trusted Stores in April 2017 according to Search Engine Journal, asks shoppers after checkout whether they want to receive a survey; because the invitation is triggered by a real order on the merchant's site, the resulting reviews come from confirmed buyers and feed the seller ratings shown in Shopping and Search ads. When Shopify disabled checkout pop-ups in August 2025, the opt-in stopped appearing for many merchants, a problem fixed through an inline block in the Google and YouTube app.

Origin and evolution

Amazon has hosted customer reviews since 1995. The company has not published a launch date for the Verified Purchase label, but it was in use by 2012, when authors were noting that even free Kindle downloads carried it.

Its value grew with the scale of manipulation. In October 2015, Eric Anderson, professor of marketing at Northwestern University's Kellogg School of Management, reported that book reviews without the badge were nearly twice as likely to be one-star reviews - 9.4% against 4.8% for verified ones.

October 3, 2016 marked the main policy change. Amazon banned incentivised reviews, in which sellers supplied free or discounted products in exchange for disclosed reviews, with the exception of its own Vine programme. According to TechCrunch, a ReviewMeta study of more than 7 million reviews had found that products with incentivised reviews averaged 4.74 stars against 4.36 for those without. "We do not incentivize positive star ratings," said Chee Chew, Amazon's vice president of customer experience, describing Vine. In November 2016, Amazon capped non-verified reviews at five per week per customer, while leaving verified purchases unlimited. "The limit is five," Angie Newman, an Amazon spokeswoman, told GeekWire.

From there the badge became a target rather than a safeguard. In May 2021, the security research group Safety Detectives reported finding a database showing at least 200,000 reviews linked to refund schemes, according to Modern Retail. In July 2022, Amazon sued the administrators of more than 10,000 Facebook groups that brokered fake reviews; one group, named "Amazon Varified Buyer & Seller", allegedly offered fake reviews to sellers for $10 each, according to CNBC.

Why it matters for marketers

Reviews are one of the few signals that sit on both sides of the ad. They shape conversion rates on product detail pages, where sponsored ads land, and star ratings appear inside ad units themselves. A listing with a weak or volatile rating converts less of the traffic that advertisers pay for.

Amazon blocked more than 200 million suspected fake reviews in 2022, and says it stopped more than 250 million in 2023. Sellers' own feedback scores, which affect account health, have been under pressure too: buyer threats of one-star feedback have tested Amazon's anti-manipulation rules, which bar compensation in exchange for removing feedback even when the buyer starts the demand.

Limitations and disputes

The badge confirms a transaction. It does not confirm honesty. The commonest manipulation scheme exploits exactly that gap: a recruited buyer purchases the product at full price on Amazon, leaves a five-star review, and is refunded off-platform, typically through PayPal. The review carries the badge because the purchase was real. Researchers Sherry He, Brett Hollenbeck and Davide Proserpio tracked about 1,500 products soliciting fake reviews over nine months; their study, published in Marketing Science in 2022, found that roughly half the reviews on those products were eventually deleted, but only after an average lag of more than 100 days, according to INFORMS.

The criteria are opaque. Neither the discount threshold nor the weight given to verified reviews is published; seller guides cite cut-offs between 20% and 50% off, none confirmed by Amazon, so sellers cannot predict when a promotion will cost them the badge. Shoppers who buy in a physical shop or from another retailer are, by design, never verified on Amazon, and their reviews count for less. Independent tools that tried to grade review authenticity have also faded: Mozilla shut down Fakespot on July 1, 2025.

Regulators have not mandated verification. The US Federal Trade Commission's final rule on consumer reviews, announced on August 14, 2024 and in force since October 21, 2024, bans fake reviews, bought reviews and review suppression, with civil penalties of up to $51,744 per violation, according to Morgan Lewis. It does not require platforms to check purchases. The European Union went further on disclosure: since May 28, 2022, traders that publish reviews must state whether and how they ensure those reviews come from consumers who actually used or bought the product, under the Omnibus Directive (EU) 2019/2161. Claiming that reviews are verified without reasonable steps to check them is blacklisted as unfair.

Not the same as

Vine Review. Amazon's invitation-only programme sends free products to selected reviewers. Their reviews carry a separate "Vine Review" badge and cannot be verified purchases, since no purchase took place.

Seller feedback. Ratings of the merchant rather than the product, governed by separate rules. Amazon has accepted star-only seller ratings since August 4, 2025.

Verified purchase data. In measurement, the phrase describes transaction records used to judge advertising. PayPal pitches its transaction graph as connecting verified purchases across merchants, and Grocery TV links in-store screens to verified purchases at the product level. Neither has anything to do with reviews.

Receipt validation. The technical check that a purchase record, such as an in-app purchase, is genuine before revenue is counted. Receipt validation verifies the transaction for attribution, not the opinion attached to it.

Recent developments

Pressure has shifted from platforms' voluntary badges towards enforceable rules. The UK's Digital Markets, Competition and Consumers Act banned fake and concealed incentivised reviews from April 6, 2025, with fines of up to 10% of global turnover. On June 6, 2025, the Competition and Markets Authority accepted undertakings from Amazon to detect fake reviews and catalogue abuse, following similar commitments from Google in January 2025.

On July 24, 2026, it banned undisclosed incentivised reviews in review snippet markup, with manual actions for violations. Maps now asks visitors whether a business paid for reviews, and an April 2026 policy update banned staff-name and quota-based solicitation. Google's Business Profile documentation on review links and QR codes still collects reviews without any purchase check. The absence shows in Germany, where Maps now displays counts of reviews removed after defamation complaints; a business stating it has no record of a transaction with the reviewer is often enough to trigger removal.

The next test involves software buyers. As AI agents begin to shop on people's behalf, Experian's Agent Trust framework, announced on April 30, 2026, aims to tie each agent to a verified human. Whether a review written after an agent-made purchase deserves the same badge is a question no platform has yet answered publicly. Older terms for the same problem - the shill and the sockpuppet - suggest it will not be the last.

Summary

Who: Marketplaces such as Amazon assign the label from their own order data; Google Customer Reviews and other review services confirm buyers through post-purchase invitations; regulators including the FTC, the CMA and the European Commission set the rules around fake and incentivised reviews.

What: A badge on a customer review confirming that the reviewer bought the product through the hosting platform at a price available to most shoppers, used to weight star ratings and rank reviews.

When: The Amazon label was in use by 2012, gained ranking weight in June 2015, and became central after the October 2016 ban on incentivised reviews; disclosure and fake review rules followed in the EU in 2022, the US in 2024 and the UK in 2025.

Where: On product detail pages, in star ratings shown in search results and ad units, and in seller rating programmes on Google Shopping and Search ads.

Why: Open review systems let anyone post, so platforms need a way to separate buyers from strangers. The badge proves a transaction but not an honest opinion, and refund schemes, opaque thresholds and slow deletions limit what it guarantees.
