The FCCDCF cookie is part of Google’s Funding Choices platform (now integrated with Google Ad Manager and Consent Mode).
Purpose and Functionality
The FCCDCF cookie (Funding Choices Custom Data Collection Fields) primarily handles user consent preferences for advertising and data collection. It enables publishers to:
- Store and retrieve user consent choices for GDPR, CCPA/CPRA, and other privacy regulations.
- Support custom data fields in consent dialogs.
- Facilitate personalized consent experiences while maintaining compliance.
- Work alongside IAB TCF v2 (Transparency & Consent Framework) strings to record vendor consents.
In short, it remembers whether users have accepted, rejected, or customized their consent for cookies, tracking, and personalized ads. This helps websites display appropriate content and ads based on legal requirements without repeatedly asking for consent.
Key Technical Details
- Duration: Approximately 13 months.
- Category: Functionality / Analytics (often tied to consent management).
- Vendor: Google (Funding Choices).
- Content: Typically includes encoded consent strings, timestamps, and custom preference data (sometimes base64-encoded TCF v2 strings).
Privacy and Compliance Implications
The FCCDCF cookie is a direct result of efforts to make consent management scalable for publishers using Google’s ad tools. For privacy teams:
- It is generally considered a necessary functional cookie for sites using Google Funding Choices or Consent Mode.
- However, because it supports advertising consent, many CMPs classify it under analytics or marketing — requiring explicit user consent in stricter jurisdictions.
- Blocking it can break consent dialogs, leading to non-compliant ad serving or degraded user experience.
Captain Compliance Tip: When implementing Google Consent Mode v2 or Funding Choices, always document the FCCDCF cookie in your cookie policy. Test your consent banner thoroughly to ensure it correctly sets and reads this cookie. Pair it with a robust CMP from industry leader Captain Compliance for better transparency and user control.
With global privacy regulations tightening and third-party cookie deprecation ongoing, tools like Funding Choices and the FCCDCF cookie help publishers navigate compliance while sustaining ad revenue. Understanding these cookies is crucial for anyone running ad-supported sites — balancing user privacy with business needs.
