EU Political Ads Regulation enforcement tightening on April 1
Google announced that its Ads API and Google Ads scripts will introduce stricter account-level enforcement for the European Union Political Ads Regulation, with changes taking effect on April 1, 2026. If a Google Ads account contains campaigns that have not declared their EU political advertising status, all mutate calls related to campaign management will fail with an MutateError.EU_POLITICAL_ADVERTISING_DECLARATION_REQUIRED error.
This update uses a PMC cover because no suitable source image was available when checked on 8 Sept 2026. Available source and video links are retained.
What changed
Enforcement applies across API versions v20, v21, v22, and v23. The contains_eu_political_advertising field has been backported to v20.2, v21.1, and v22.1.
Why it matters for advertisers
For you, this means verifying that all campaigns in your account have EU political advertising declarations on file before April 1 to avoid API disruptions.
