The 2024 International Codes® (I-Codes®) have undergone substantial formatting changes as part of the digital transformation strategy of the International Code Council® (ICC®) to improve the user experience. The changes, promoting a cleaner, more modern look and enhancing readability and sustainability, include:

• Single column text format and modernized font styles improves readability
• QR Codes replace vertical margin sidebars and arrows to identify code changes more accurately
• Shading for table headers and notes improves locating tables and applicable notes
• Grouping of associated content brings tables and figures immediately after the parent section
• Users have capability to validate authenticity of their book and register it with the ICC to receive incentives.
