The European Union (EU) Regulation 2024/900 about the transparency and targeting of political advertising will take effect on October 10, 2025. As a reminder, Microsoft Advertising introduced a political advertising declaration requirement for all customers in September 2025.
Microsoft Advertising doesn’t allow political advertising on its platform. Campaigns intended for political advertising won’t be allowed to proceed according to our policies. We expect our customers to take steps to ensure compliance with this policy.
We've updated our political advertising policies to include the EU regulatory requirements. To comply with the regulation, you are required to declare whether campaigns are intended for political advertising before campaign creation and import. If it is, any political advertising must be removed to proceed.
What’s new:
- We'll collect declarations regarding whether creatives are political through a new element labeled as IsPolitical made available in the Microsoft Advertising API. Customers will be able to send the declaration using IsPolitical.
- If IsPolitical is set to true, attempts to add or update the campaign will fail with the error: PoliticalCampaignsAreNotSupported because we don’t support political advertising.
- Additionally, if this field is empty or null in a GET call or bulk download, its value is treated as false. If you don’t explicitly declare that the campaign constitutes political advertising, by default, it will be assumed to be a declaration that the creative is non-political.
What’s not changing:
- Existing campaigns will continue to run without interruption.
- We'll continue to conduct regular reviews of all ads to confirm that they are not intended for political advertising. Campaigns identified as being intended for political advertising will be treated as an egregious violation and appropriate steps will be taken.
