IS 19000:2022 Explained: India's Standard for Online Consumer Reviews

Short answer: IS 19000:2022 is India’s national standard for online consumer reviews. Published by the Bureau of Indian Standards with the Department of Consumer Affairs and effective from 25 November 2022, it sets out how review platforms and businesses should collect, moderate and publish reviews. It is voluntary, not mandatory — there is no penalty for ignoring it — and it is adapted from the international standard ISO 20488:2018. Its practical value is that it gives Indian consumers and businesses a named, published benchmark to hold a platform against.

The basics

The three duties it defines

The standard organises everything around three obligations that fall on the review administrator.

• Collection. Reviews should be gathered in a way that does not bias the outcome. That means not soliciting only customers you expect to be happy, taking reasonable steps to confirm the reviewer actually had the experience, and disclosing any incentive that was offered. Requesting reviews is fine; requesting them selectively from likely promoters is not.
• Moderation. Criteria for rejecting or removing a review must be published in advance and applied identically to positive and negative reviews. This is the clause with the most teeth in practice, because selectively deleting criticism while keeping praise is precisely what destroys a rating’s meaning.
• Publication. Reviews should be displayed without distortion — no quiet reordering to bury complaints, no suppressing low scores from the average, and the basis of any aggregate score should be explained. Consumers should be able to see how many reviews a score came from and over what period.

What it asks for, in plain terms

• Publish your review policy, including exactly when a review will be rejected or taken down.
• Take reasonable steps to verify that a reviewer had the experience they are describing.
• Disclose incentives. A review obtained in exchange for a discount, a free product or loyalty points must be labelled as such.
• Do not edit the substance of a review. Correcting obscenity or removing personal data is different from changing what someone said.
• Apply moderation symmetrically to positive and negative reviews.
• Give businesses a right of reply, and give reviewers a route to challenge a removal.
• Keep records of moderation decisions so they can be audited.
• Show the number of reviews behind an aggregate score, and the period it covers.

Voluntary — so does it matter?

It matters in three concrete ways, none of which depend on it being enforceable.

• It gives you language for a complaint. Telling a platform “your moderation is unfair” achieves little. Telling it “removing negative reviews while retaining positive ones on the same criteria is contrary to the symmetric-moderation principle in IS 19000:2022” is a specific, citable objection.
• It interacts with law that is not voluntary. The Consumer Protection Act, 2019 and the Consumer Protection (E-Commerce) Rules, 2020 already prohibit unfair trade practices and misleading representations, and the Central Consumer Protection Authority can act on them. A platform that departs from the standard is more exposed under those instruments, because the standard describes what reasonable practice looks like.
• It is a checklist for choosing a platform. If a review site will not publish its moderation criteria or explain how a score is computed, that tells you what its numbers are worth.

How to check whether a platform follows it

• Is there a published review policy stating when reviews are rejected or removed? If not, nothing else can be assessed.
• Are incentivised reviews labelled? Look for a disclosure marker, not a line buried in the terms.
• Is the review count shown next to the average, and can you see the distribution rather than only the mean?
• Can businesses reply publicly? A platform with no right of reply is publishing one-sided claims.
• Is there a stated verification method? “Verified” should mean something specific — a confirmed purchase, not merely a confirmed email address.
• Is there a route to challenge a removal? Symmetric moderation is meaningless without an appeal path.

Frequently asked questions

What is IS 19000:2022?

It is the Indian national standard for online consumer reviews, titled “Online Consumer Reviews — Principles and Requirements for their Collection, Moderation and Publication”. The Bureau of Indian Standards published it with the Department of Consumer Affairs and it took effect on 25 November 2022. It defines how organisations that publish reviews they did not write should gather, moderate and display them, and it is adapted from the international standard ISO 20488:2018.

Is IS 19000:2022 mandatory in India?

No. It is a voluntary standard, so there is no direct penalty for a platform that does not follow it. Its force is indirect: it establishes a published benchmark for reasonable practice, which makes it useful when complaining to a platform or a regulator, and it sits alongside the Consumer Protection Act, 2019 and the Consumer Protection (E-Commerce) Rules, 2020, which do carry legal consequences for unfair trade practices and misleading representations.

What does the standard say about fake reviews?

It approaches the problem through process rather than detection. Platforms are expected to take reasonable steps to verify that a reviewer actually had the experience described, to publish the criteria under which reviews are rejected, and to keep auditable records of moderation decisions. It also requires that incentives be disclosed, since an undisclosed paid review is a form of fabrication even when the writer was a real customer.

Does IS 19000 stop companies deleting bad reviews?

It requires moderation criteria to be published in advance and applied equally to positive and negative reviews, which is the principle that removing criticism selectively breaches. Because the standard is voluntary the requirement is not directly enforceable, but a platform that deletes negative reviews while keeping comparable positive ones is departing from a documented national benchmark, and that is relevant if the conduct is challenged as an unfair trade practice.

Who does IS 19000:2022 apply to?

Any organisation that publishes consumer reviews it did not author — online marketplaces, dedicated review platforms, travel and hospitality sites, and brands that host customer reviews on their own websites. It does not cover an organisation’s own descriptions of its products, paid expert or editorial reviews, or private feedback that is collected but never published.

How is IS 19000 different from ISO 20488?

IS 19000:2022 is India’s national adoption of the same subject matter that ISO 20488:2018 addresses internationally, so the core principles — unbiased collection, transparent and symmetric moderation, undistorted publication — are shared. The practical difference is jurisdictional: IS 19000 is issued by the Bureau of Indian Standards and is the reference point Indian consumers, businesses and regulators would cite, and it sits alongside India’s own consumer protection legislation.
