The 2024 International Codes (I-Codes) feature significant formatting enhancements as part of the International Code Council’s (ICC) digital transformation initiative, designed to improve usability and the overall reader experience. Key updates include:

• A clean, modern design with a single-column layout and updated font styles for improved readability.
• QR codes replacing traditional margin sidebars and arrows, allowing users to identify code changes more accurately and access additional resources quickly.
• Shaded table headers and notes, making tables and related information easier to locate and reference.
• Better organization of content, with tables and figures placed directly after the sections they support for more efficient navigation.
• A built-in authentication and registration feature, enabling users to verify the authenticity of their book and register it with the ICC to receive exclusive benefits and incentives.

These improvements enhance clarity, accessibility, and sustainability while providing a more user-friendly code reference experience.
