Which advertising standards agency handles a false claim in the United States, and the one place no body reviews at all
There is no American equivalent of the ASA. Three different organisations share the work, only one of them can fine you, and none of the three reviews what an AI assistant says about your product.

If you are looking for the Advertising Standards Agency, you are looking for a British organisation and its name is the Advertising Standards Authority. The United States has no single counterpart. The work is split three ways: the Federal Trade Commission enforces the law, the National Advertising Division runs voluntary industry self regulation, and each platform runs its own private rulebook. Which one you deal with depends on who complains, and only the first of the three can impose a penalty.
The three bodies, read on 21 October 2026
| Federal Trade Commission | National Advertising Division | The platform | |
|---|---|---|---|
| What it is | A federal agency | A unit of BBB National Programs, which its own page calls independent and non profit, founded 1971 | A private company: Google, Meta, Amazon, a broadcaster |
| Is it government | Yes | Its page states plainly that it is not a government entity and is not affiliated with a government agency | No |
| Who can start a case | Consumers, competitors, its own staff | Businesses, trade associations, consumers, and its own monitoring, which its page puts at roughly 20 to 25 percent of cases each year | Anyone who clicks report |
| What it can do | Investigate, sue, order money back | Recommend changes publicly; participation is voluntary | Remove the advertisement and suspend the account |
| If you refuse | Court | It refers the matter to the Federal Trade Commission and issues a press release about the referral | Nothing to refuse. The account is already off |
That last row is the part most people miss. The National Advertising Division is voluntary right up to the point where it is not, because a refusal becomes an FTC referral with a press release attached. In practice a competitor challenge at the NAD is the fastest route to getting a rival's claim changed, and it is the route most often used.
What the British body actually is, since most of this search is looking for it
The Advertising Standards Authority, read on its own about page on 21 October 2026, was established in 1962 to keep United Kingdom advertising legal, decent, honest and truthful, and it works alongside the Committee of Advertising Practice codes. That page names the system and the complaint handling and does not set out its powers, so if you need the enforcement detail read the ASA's own rulings rather than its introduction. It covers advertising in the United Kingdom. It is not the body to approach about an American campaign, and an American business running advertising into Britain is inside its remit.
For what the CAP Code permits a British advertiser to claim, we have a separate page on advertising standards in the UK.
Which one to use, by the problem you have
- A competitor is making a claim you can disprove. Challenge it at the National Advertising Division. It is built for exactly this and the decisions are published.
- You have been accused of a false claim. Get the substantiation file together first: the test, the date, the sample, the person who ran it. Every one of these bodies asks the same question, which is what the claim rests on.
- Your advertisement was rejected by a platform. That is a policy decision, not a standards decision. Read the policy, fix the asset, appeal inside the platform. No regulator will help.
- A consumer was misled and lost money. That is FTC territory and it can order redress.
The place with no standards body at all
Every one of the three above reviews an advertisement: something you wrote, paid for and published. None of them reviews an answer. When a buyer asks ChatGPT, Gemini, Perplexity, Claude or Google AI Overviews who to buy from in your category, the answer names businesses, describes them, and sometimes states a price or a limit. That text is not your advertising, so no advertising standards body has a route into it, and it is not a search result, so the search quality processes do not apply either.
What that means in practice is that an assistant can describe your product incorrectly, or name your competitor and not you, and there is nobody to complain to. The only available remedy is to know it is happening. Our own citation audit of 597 readings across ChatGPT and Gemini found review directories accounted for 0.8 percent of all cited sources, so the reflex of fixing your directory listings does not reach this. The engines mostly read documentation, vendor sites and small specialist publishers.
Measuring that is what we sell: a dated, repeatable reading of what the five assistants say about your category and your business, with your name absent from the prompt so the answer is not primed. It is a measurement rather than a regulator, and it is the only thing in this area a buyer can actually act on. We are not a standards body, we do not clear advertising copy, and nothing here is legal advice.
The substantiation file, which solves most of this before it starts
Every body above asks one question: what does the claim rest on. A claim file that answers it has the claim written exactly as published, the evidence, the date the evidence was produced, the sample or method, and the name of the person who stands behind it. Build it when you write the claim, not when you are challenged, and keep it for as long as the claim runs.
Questions about advertising standards in the United States
Is there an American Advertising Standards Agency?
No single one. The closest functional equivalent to the ASA is the National Advertising Division, and it is self regulatory rather than statutory. The legal power sits with the Federal Trade Commission and with state attorneys general.
Does the National Advertising Division cost money to use?
A competitor challenge carries a filing fee that varies with the challenger's size, and the process runs to a published decision. Consumer complaints and self monitored cases do not.
Can I be fined by the NAD?
No. It recommends. The consequence of refusing is the referral to the Federal Trade Commission and the publicity that comes with it.
Who regulates influencer disclosure?
The Federal Trade Commission, through its endorsement guidance, and the brand carries responsibility alongside the creator. Platform policy sits on top of that and is usually stricter.
Who do I complain to about what an AI assistant said about my company?
There is no standards body with jurisdiction over an assistant's answer. The practical route is to measure what is being said, find which sources the answer was built from, and publish better material at those sources. That is the work, and it starts with the measurement.
