IAB TCF v2.2 & v2.3
At Lawwwing, we are committed to implementing the highest standards of data privacy on the internet. As part of this commitment, we follow the guidelines of the IAB Transparency and Consent Framework (IAB TCF) version v2.3, which is currently in force.
Lawwwing is certified by the IAB as a registered TCF provider (ID: 405):
Below, we provide information about what the IAB TCF is, why it is important for online publishers, and how you can enable this functionality in Lawwwing.
What is the IAB TCF?
The IAB TCF, or IAB Transparency and Consent Framework, is a set of standards and guidelines developed by the Interactive Advertising Bureau (IAB).
Its goal is to help the digital advertising industry comply with data privacy regulations such as the European Union’s General Data Protection Regulation (GDPR).
The TCF enables publishers and advertisers to collect user consent transparently and provide clear options regarding how user data is used.
For online publishers, complying with the IAB TCF is important for several reasons:
- Transparency: It provides a clear and standardized way to collect user consent and explain how data is used, which helps increase user trust.
- Compatibility: By complying with the TCF, publishers can work more seamlessly with advertisers and other participants in the digital advertising supply chain that also follow the framework.
Why is IAB TCF v2 important?
IAB TCF v2 represents the evolution of the IAB consent framework and introduces important improvements over previous versions, strengthening transparency, user control, and interoperability across the advertising ecosystem.
Key advantages include:
-
Compatibility with Google Consent Mode v2 IAB TCF v2 works with Google Consent Mode v2, allowing publishers to communicate the user's consent status to Google using the IAB consent framework.
-
Advanced consent management Users can grant or withdraw consent for specific data processing purposes, giving them greater control over how their data is used.
🔄 Framework evolution: from v2.2 to v2.3
The TCF framework continues to evolve to adapt to new regulatory requirements and recommendations from European data protection authorities.
IAB TCF v2.2
Version v2.2, released in May 2023, introduced several important changes to the framework:
- Stricter requirements for the use of legitimate interest as a legal basis.
- Increased transparency regarding vendor disclosures.
- Clearer consent interfaces for users.
- Stricter operational rules for CMPs (Consent Management Platforms).
This version was the primary standard across the industry during 2023–2025.
IAB TCF v2.3 (current version)
Version v2.3 is the latest evolution of the framework and is now officially in force within the IAB ecosystem.
Some of its main improvements include:
Greater transparency for users
Consent interfaces must provide clearer information about:
- Consent duration
- Versions of the consent string
- A clearer distinction between purposes such as advertising, personalization, and measurement
The framework also encourages the use of clearer and more user-friendly language.
More standardized interface elements
Version v2.3 introduces clearer guidance for consent UI design, including:
- Improved visual accessibility
- Clearer accept, reject, and manage preferences options
- More consistent consent experiences across different websites
Reduced use of legitimate interest
In v2.3, certain purposes related to advertising, personalization, or content require explicit user consent.
This strengthens user control over how their personal data is used.
Stronger publisher control over vendors
Publishers can:
- Define restrictions on the legal bases declared by vendors
- Require consent even when a vendor declares legitimate interest
- More precisely manage which vendors can operate on their website
Stronger compliance signals and consent records
CMPs must ensure that:
- If no valid consent exists, personal data must not be processed
- Secure consent logs are maintained for auditing or regulatory inspections
Compatibility with the Global Privacy Platform (GPP)
TCF v2.3 improves interoperability with the Global Privacy Platform (GPP), enabling better management of privacy signals across multiple jurisdictions and regulatory frameworks.
Implementation status in Lawwwing
✅ Lawwwing fully supports and operates with IAB TCF v2.3, incorporating all necessary technical adaptations, including:
- Updated consent interfaces
- Advanced vendor management
- Secure consent logging
- Compatibility with the latest advertising ecosystem standards
During the transition period, we continue to maintain compatibility with configurations based on TCF v2.2, but we recommend using v2.3 to ensure compliance with the most recent IAB standards.
