Pennsylvania law forces AI-generated ads to carry clear labels

Pennsylvania has passed a law requiring any advertisement generated or significantly altered by artificial intelligence to carry a clear label. Governor Josh Shapiro signed the Artificial Intelligence Deceptive Advertising Act on Thursday, according to The Verge AI and Google News AI.

Why it matters

This is not a federal rule, but Pennsylvania is a large state. The law covers any ad format: video, audio, images, and text. If a business runs an ad in Pennsylvania that has been generated or heavily modified by AI, the ad must include a disclosure. The law says the label must be in the same format as the ad itself, so a video ad gets an on-screen label, an audio ad needs a spoken disclosure, and so on.

The law aims to prevent misleading or deceptive ads, especially as AI-generated content becomes harder for consumers to distinguish from real footage or real voices. The Verge AI reports that the law applies to any ad distributed in Pennsylvania, not just those made by Pennsylvania companies.

What the law requires for AI-generated ads

The Artificial Intelligence Deceptive Advertising Act spells out that any ad "significantly modified or generated by artificial intelligence" must carry a disclosure. The disclosure has to be "clear and conspicuous" and use the same media type as the ad. For example, a digital billboard needs to display the label visually; a radio ad needs an audio statement.

Pennsylvania's approach is broad. It does not limit the rule to political ads or certain industries. Any business running ads in the state, whether through local TV, radio, print, outdoor, or digital platforms, must comply if they use AI in the creative process. The law does not define a threshold for what counts as "significant modification" in detail, so businesses will need to review any ad with AI involvement.

There are penalties for noncompliance. The state can pursue action against companies that do not properly label their AI-generated advertisements. The full details on enforcement and fines were not in the coverage from The Verge AI or Google News AI, but Governor Shapiro's signature makes the rule effective law.

What this means if you run a business

If you advertise to Pennsylvania residents, you now have a new compliance step. Every ad campaign using AI tools, whether for headline writing, image generation, or voice synthesis, must be checked for this rule. That includes work done by outside agencies, not just in-house teams. If your ad is distributed in Pennsylvania, even on national platforms, it needs the AI label if AI was involved.

The practical effect is more review time and possibly new workflows. Creative and legal teams will need processes to flag AI involvement and add the required disclosures. If you run multi-state or national campaigns, you may have to create separate versions for Pennsylvania or include the label everywhere to avoid mistakes. This is similar to how privacy laws like CCPA have forced broader compliance changes beyond one state.

For now, Pennsylvania is the only state with this kind of rule, but there is no guarantee it will stay that way. Businesses should expect more states to watch how this is enforced. If you rely on AI-generated content for marketing, you may want to track developments in other states and review your overall disclosure strategy.
