Google Ads adds California, South Korea and Vietnam to AI label overlays.

Google Ads now shows visible AI labels on ads targeting California, South Korea and Vietnam when advertisers mark assets as AI-created or edited. The three join the European Union, India and New York on Google's list.
Search Engine Roundtable spotted the change on 5 November in Google's help page on AI content labels, and Google also updated its Merchant Center product data specification. The help page says that in some places the label appears on the ad itself as an overlay, and it now lists six: the EU, India, New York, California, South Korea and Vietnam. Google's documentation ties the list to local rules that require ads with certain AI-generated or edited assets to be disclosed or labelled.
Outside those places, labelling still has an effect. Any asset an advertiser marks as AI-generated or edited is disclosed in the "How this ad was made" section of the My Ad Center panel, which users can open from the three-dot menu on ads across Search, YouTube and Discover. Advertisers can set the label in Google Ads and its other ad tools, see each asset's status in the asset library, and may get a "Review assets" prompt when an ad looks as if it needs one. They can also add their own AI labels in their design tools without breaking Google's rules on text overlays. Images and videos made with Google's own ad tools carry SynthID watermarks and C2PA metadata.
Google's page does not give a date from which the overlays apply in the new regions, and it does not say whether more markets will follow.
No Gulf market is on the list, so campaigns aimed only at Saudi Arabia or the UAE do not get the on-ad overlay. Regional brands whose campaigns also target the EU, India or the newly added markets do, and agencies should mark AI-made assets accurately in every account, because the disclosure in My Ad Center applies everywhere.
Why it matters
Ads using AI-made assets now carry visible labels in more markets, and accurate labelling is becoming routine campaign hygiene for agencies running multi-market accounts.
