Measures for Labeling AI-Generated Synthetic Content (国信办通字〔2025〕2号), issued by CAC, MIIT, MPS and NRTA, 2025, Arts. 4-5

A citation is an address, not a summary. The first part names the law; what follows narrows it to the exact section, article or paragraph.

What follows is LexLint's own research summary of this law, not legal advice.

In force since 1 September 2025.

An AI transparency rule binding public and private bodies.

As of 14 August 2026.

What it requires

  • Add a user-perceptible label to AI-generated text, image, audio, video, and virtual-scene content
  • Embed a machine-readable identifier in file metadata carrying the generation attributes and your provider name or code
  • Check incoming content for labels and add a risk prompt to unlabeled or suspected-generated content, if you distribute content others supply
  • Never delete, alter, forge, or conceal a required label

What it makes you log

Logging duty

Articles 4 and 5 require an explicit, user-perceptible label and an implicit file-metadata label for generated or synthesized content; neither article states a duty to log, record, or later produce evidence that a labeling event occurred. A separate provision of the same Measures, Article 9, requires retaining logs of recipient information for no less than six months when a service provider supplies unlabeled content at a user's request, but that duty sits outside this instrument's own citation (Articles 4 and 5) and is not carried here.

What this law does

Drafted with AI from the cited sources under the direction of UnGovr staff. UnGovr holds editorial responsibility for this page.

Internet information service providers must add an explicit, user-perceptible marker to AI-generated or AI-synthesized text, image, audio, video, and virtual-scene content, and must embed an implicit, machine-readable identifier in file metadata carrying generation attributes and the provider's name or code. Content-distribution platforms must check incoming content for labels and add a risk prompt to unlabeled or suspected-generated content.

No person or organization may maliciously delete, alter, forge, or conceal a required label. The accompanying mandatory national standard GB 45438-2025 sets the technical parameters for both label types and takes effect the same date; no official standards-body URL for GB 45438-2025 is available independent of a commercial reseller, so it is described here rather than authored as its own instrument.
